700 MHz Athlon 136
News.com is reporting that AMD will release a 700 MHz Athlon this week, pushing them even further ahead in the MHz race against Intel. I hope it works well, because the article also points out that AMD is still not doing well financially...
Some things... (Score:3)
1. A better relationship with Microsoft- Microsoft you say? How can he really think anyone needs to be friends with Microsoft? Well you need to take into account something Intel realized a long time ago. Microsoft will not go away, kinda like gum stuck to the bottom of a pair of Airwalks. Linux is great yada yada, but the linux geeks of the world don't have the mass buying power that PHB's have. 3D Now extensions in M$ products like office and maybe some special support in NT and 98 for it also.
2. An intelligent marketing director- AMD is missing something that Intel has and it's not money. According to Intel's commercials if you buy their processors you can actually move into the internet and cute bears will walk around your screen all because of the P3. All AMD has to do is get people to believe they can do some extraordinary stuff with the Athlon and when it comes down to buying a P3 system or an Athlon system Jonny and Suzy Nontechsavvy will buy the Athlon.
3. Some kind of relationship with any computer manufacturer that has TV commercials- People watch alot of TV so when they see a Dell or Gateway commercial with the AMD logo they'll think the processors are damn cool, like they do now with the P3. Intel makes a majority of their megabucks selling though computer manufacturers, learn the lesson AMD.
4. Really snazzy SMP- This fits in with all of the other suggestions. Make the SMP run really snappy with up to alot of processors, companies like Dell and Compaq will put them in their servers and then sell NT on them and put them in commercials. If AMD can keep prices low we might even see consumer SMP boxes for under 2000$ with any distro of linux or Windows NT or 2K from a said computer company. SMP is sorta like RAID in that it would work wonders in a consumer environment but never panned out and has for the most part been relagated to enterprise class machines. SMP just leaves so much room for expansion on a system, if you really need more power you can buy a second processor and you're set, no worrying if you can find a slightly faster chip to work in your system or if you just need awhile new system. Thats why I got a dual motherboard, when I need more speed I want to pay 200$ for a second processor, not have to upgrade to a while new motherboard AND faster processor. When I need a faster system still I can replace both processors and up the bus speed by 133mhz giving me a much longer life span out of my investment. This is good for Joe COnsumer. Slap the motherboard companies to get their SMP boards out AMD, you need it.
Ok that's all.

AMD owes Motorola BIG TIME this is going to happen. Motorola is also looking for any excuse to close all it's old high labor cost U.S. fabs soon, and outsource production entirely. This is probably one reason it formed a partnership with AMD awhile back and shared its highly valuable copper technology with AMD.
AMD could not put out a 2GHz processor by Christmas of this year. At best, they could perhaps clear a little over 1GHz.
No KIDDING. exaggeration is a literary technique used to show absurdity, and to emphasize points, it's clear that I did not in any way predict that AMD would release a 2GHz CPU this year.
In no way would AMD be screwed if the KX133 never appeared. There's no palpable benefit with it. With their current chipset, future Athlons would still be faster (in some cases significantly) than competing P6 (the processor family which includes the Pentium III) offerings.
Faster yes, but there is virtually no marketing, and most OEMs are not selling or advertising Athlon systems. Gateway is not going to make any more AMD systems for instance. Here's a revolutionary idea: people buy things they know about. A lot of people don't know about the Athlon because it's not highly visible in consumer markets now. When the KX 133 comes out it will sell well be because of all the features that will be offered with this chipset. However, the CPU will become less and less important to 3D gamers as the majority of CPU intensive rendering will be done by geometric co-processors on the new generation of graphics cards coming out this month. For the non-gaming educated "build it yourself" market, the best & cheapest solution is a dual-celeron SMP set up for Linux. I personally plan on buying a Athlon because I have no need for SMP and win 9x doesn't even support SMP.
Transmeta? You're joking! The Transmeta cpu will only have its details announced in November!
If you had read the patents on this (as I have) you too would be impressed. I MUCH prefer RISC processors (such as my G3) to CISC x86 processors. If I weren't into gaming I would buy a G4 and load Red Hat Linux 6.0 on it, but since there aren't that many games for Linux & Apples I have to buy an x86. However, Transmeta looks like it might be a 64-bit CPU capable of dynamic reprogramming of the microcode, which would enable the CPU to switch back and forth between x86 and 64-bit RISC in REAL TIME.
And that sure as hell is worth waiting around for, ESPECIALLY since I already have to wait till November for the KX 133.
VIA is going nowhere fast with Cyrix and Centaur. VIA "let go" almost half of Cyrix's team, and a lot of the rest left on their own.
Duh. Everyone knows cyrix chips can't compete (*although the MSN free computer deal sold a hell of a lot of them). However, what VIA did acquire was Cyrix's modern fabrication infrastructure. This they can use to produce a high quality, cheaply made, competitive chip, that they could dump on the U.S. markets for half the price of what current CPUs are selling for. If they don't follow this strategy, I'd be quite amazed.

i find it strange that intel or AMD are not shipping multiple processor SECC packages. maybe its because of space constraints for the cache but then each processor can have only 256k and it'll fit.
coppermine is very interesting. It does not have any external L2 backside cache like the PIII and athlon. I see this as a very good opportunity for intel to put two coppermine dies on a single Slot 1 package. I do not believe it is very hard to cool as the coppermine dies are the same height unline the cache and PIII dies. Also, an athlon like heatsink can help cool it. i think AMD should do the same with an integrated cache athlon die.
Better yet, both companies can make a double sided Slot 1/A package with their chips on the PCB on both sides, requiring a sandwich cooler. They might be able to fit 8 chips on the package. it'll make a nice SMP system. this is the advantage for slot. then maybe with a new chipset, single slot athlon/PIII boards can ahve 8 processors and dual slot can have 16 processors bwhahahaha.

So what does it mean to AMD if VIA can't deliver on the Apollo KX133 chipset? It means that you give Intel a chance to get back in the market with 700 MHz Coppermines in November. It also means that you reaffirm the general sense that AMD can't deliver it's products in a timely manner. Although waiting for the KX133 rewards consumers with lower CPU prices as the OEM market has demonstrated drastic drops in Athlon CPU prices this month, it prevents AMD from signing lucrative OEM contracts at a critical time.
In the consumer markets, people a waiting for AGP 4x, and will settle for an Apollo Pro chipset and a Pentium 3 rather than wait 2 months for VIA to release the same product for the Athlon. Personally, I don't plan on buying any more Intel products due to their shameless attempts to strong arm Taiwanese manufacturers into not making Athlon motherboard, the bogus Rambus fiasco and Intel's bribery of Gateway to stop making machines with AMD CPUs.
Essentially, AMD is making mistakes that they _Could_Have_Learned_from Intel. For instance, Intel makes its own chipsets, and charges people royalties to use them. AMD has virtually out-sourced its chipset design and fabrication to VIA who recently acquired Cyrix. Now, you've got to ask yourself, how dumb can the execs at AMD be? And you have to be pretty suspicious about how long it's taking VIA (pre-earthquake estimate for the KX133 release was November) to get out a decent motherboard for the Athlon CPUs, as the changes they'll have to make are hardly drastic. Current Athlon boards already have the Alpha 200 MHz bus, already support PC133 SDRAM, all that VIA needs to do is slap on the AGP 4x components and onboard UDMA/66 which is technology they_already_have. You have to wonder if the aquisition of Cyrix has made them a little less eager to see AMD survive, after all should AMD go bankrupt, that would leave the entire low end PC market at their disposal.
AMD's moving of their main Fab to Dresden was a smart play, as is the production of Motorola G4 chips (and indeed the partnership with Motorola whereby AMD has access to Motorola's copper CPU technology), However, why not shift the whole operation to Germany? Why put yourself at the mercy of VIA, and the Taiwanese?
To be blunt, AMD could put out a 2 GHz CPU by Christmas and still be screwed if VIA is significantly late with the KX133. I for one will not wait forever for this board, especially with all the information out now on the Transmeta CPU.

No, this isn't a flame...
What holds my interest in the Athalons isn't the tit-for-tat clockrate match with Intel (I mean, who really cares who owns the fastest CPU this month?). What I'm far more interested in AMD producing is the SMP versions.
To me, the biggest pain-in-the-ass right now is the P3 / Xeon product split. The slot1 architecture limits me to 2 CPUs - if I want more, I have to get Xeons, which are a huge cost uplift. Here's a good example:
A Compaq 1850R and a 6400R are very similar machines in everything but the CPU architecture (yes, there are a couple of other important advantages in the 6400, but not that big). I pay about $4000 for a 1 CPU 1850R, and $1300 for an additional CPU. For a 1 CPU 6400R, it's $8000, plus $1800/CPU.
Now, if AMD can come out with a chipset/motherboard that has 4-8 slots, AND I can stick the "commodity" (ie non-Ultra) Athalons in it, well, then, GoodBye Intel! AMD needs to realize that there is a huge opportunity here at the P3 / Xeon split, a place that they can heavily exploit. All the better, since Intel will NOT be able to remedy the situation, other than lower the cost of Xeons, something they are loath to do.
Having an single architecture that will linearly scale up through at least 8 (and preferably to 12 or so) would be a real advantage to AMD. I would much prefer to see them press ahead with putting into production large SMP-capable chipsets and such than worry about getting the absolute highest megahertz CPU out.
Just in case I'm not totally clear here, what I want is to be able to use the SAME CPU from the low-end machines to the high end ones. Now, I know I'll get better performance by buying the Athalon Ultras (much more L2 cache), but I'd at least like the option of using the base Athalons, rather than be forced to use the more expensive chips, just because the manufacture want me to (that's the reason for the Slot1 vs Slot2 division - it's a pure Intel marketing decision).

I remember the transformation from 16-bit to 32-bit happened literally overnight. The 386 came out, was completely backwared compatible and all you had to do was run Windows in standard or 386 enhanced modes. Now, we are losing backwards compatibilty and it's not like these Merced chips are out tomorrow...wasn't this supposed to come out sometime closer to 2001? To me, this leap to 64-bit processing is more about changing the instruction set than changing the amount of data you can crunch. That's what worries me since it means that everything is going to be emulated and will probably run as crappy as my Win16 applications run in NTVDM.
Unless Transmeta fixes that but that is another discussion thread entirely...
Regarding cost...of course. But costs come down eventually as the technology becomes adopted. It may take longer to trickle down from servers to consumers but eventually it gets there. Alpha is not an accurate example because that wasn't just about "better". NextStep was "better". Better gets you nothing...if "better" also means "different" and "not backward compatible".
Time and time again, companies prove that abandoning backwards compatibility is the WORST thing you can do. Commodore killed themselves overnight by sinking all their money into the Amiga 4000, which could not use any of the software or hardware from any previous Amiga line. And NeXT, too, learned that lesson. Microsoft, I dare say, is the success they are simply because they are still dragging along that old backward compatibility mentality, and will even be doing so in their Millenium product.
All I'm saying is that I see 128-bit everywhere in marketting hype (look at Apple's new G4 descriptions) and 64-bit seems to be 1998's big buzzword. If Intel finally comes out with 64-bit some time towards the end of 2000, it won't be backward compatible so all the existing Pentium customers aren't going to be interested, and it won't be "cool enough" that power users will want to invest in it...so...disaster in the making?
If there was a 64-bit x86 processor, I would buy it but...my understand is that there is not nor ever will be if the company that invented x86 is finally washing their hands of it...
As far as speeds go, I dare say they can be the same rate...like I said in my original post, we now have busses running at 133MHz, the same speeds that processors were running at just a few years ago. You may scoff at the idea of higher bus speeds but ten years from now when my kids are reading SlashDot archives on 500MHz holographic displays imbedded in their eyeballs, they'll have to give a knowing smirk...
And regarding single point of failure...I'm not talking hot swapping nor am I talking live switchovers...this isn't about 99.9% uptime for a server. I'm talking about spending $560 on a processor instead of $125 each on four of them. If that processor dies...I'm down until I can either returned it to the store (if it happened within 30 days), return it to the manufacturer (if it happened within a year) or return it to the ground from whence it came. If one of the cheap-o processors dies, I can reboot and come back with a working system, albeit with only 1 or 2 processors.
It's like RAM and hard drives...is there anyone out there that has only one single 256MB DIMM or 20GB drive in their possession? Or more likely...you have every spare DIMM slot and IDE/SCSI connector filled even if you had to pull out a crusty 16MB DIMM or 2.1GB to do it?
Processors, IMHO, should be no different. I don't need the same processor speeds in a BeowOOOOOlf cluster, do I? I don't need the same processors speeds for SETI@Home, do I? If the architeture had been designed for SMP years ago, I don't see why processors could be as board independant as RAM or hard drives.
Okay...enough from me...the issue just hits a nerve for me because I really, honestly, have not felt love for my PC system since the 486 that lasted me for six years. Everything else seemed literally like junk the second I booted it. I think that since the Pentium era begun, I haven't been able to keep a system for more than two years...sad...really sad...

Following your line of logic, AMD ought to get in the ram business as well. We all know that Intel is creating a new type of ram, and they probably won't liscense it out. So amd had better start working on it's own ram type as well that it will produce in house, otherwise it will have to depend on outside companies to produce ram that will work with it's cpu's.
AMD has decided NOT to get in the chipset market because it DEPENDS upon support from 3rd party manufacturers. I have serious doubts that AMD would be able to make a chipset of the same quality of a VIA chipset. On top of that, they would have to FURTHER divide their production facilities between chipsets, k6's, and k7's. They don't want to make chipsets! They won't make as much money off of them as the extra k7's they could stamp out!
You question the length of time to get a K7 chipset by VIA? "minor" changes? The bus design is COMPLETELY different. The EV6 bus is a completely different animal, far more advanced than the design intel uses for it's stuff. And alot more complicated.
If VIA really wanted the low end market to itself, all it would have to do is stop producing Socket 7 chipsets that'll work with the k6. I'm sure they wouldn't have too many problems doing that... It'd be silly for them to drive their major source of revenue out of business; the low end market has very little profit in it, if any. That's why amd has been loosing so much money lately.

AMD can and does make chipsets. The 750 chipset currently used for Athlon boards already includes the 200MHz Alpha EV6-based FSB. VIA is not going to change this. What VIA is going to do is integrate:
1) UDMA 66 support on the motherboard so you won't need a PCI controler (the same thing that Abit already offers with the Be6 BX boards) Why is this important? For one, Linux has trouble distinguishing between a Promise UDMA/66 controller and an adaptec SCSI controller, which is highly annoying if you'd like to run both; and
2) AGP 4x, which contrary to your assertion, will be used in the near future. The new nVidia GeForce 256 AGP 4x card is comming out early this month for instance. By the way, APG 4x fast writes circumvent system memory and speed up all data transfers from the CPU to the graphics card, which is a huge performance gain.
I never wrote that VIA made bad chipsets, I wrote that Taiwan's production has been flaky recently, and I'm not sure that they can deliver products the_are_required_for_the_continued_survival_of_AMD in a timely fashion.

This would be useful in providing a way to make journalled filesystems (of which two have recently made beta releases for Linux, namely ext2 and Reiserfs) both faster and more reliable, as they could have the metadata journals written out initially to this "relatively reliable cache" rather than having it vulnerable in ordinary RAM.
1MB of battery-backed RAM would be enough for Stephen Tweedy's ext3 implementation; doubtless other uses could be imagined for larger quantities...

Extra coprocessors on the video card can't be too horrible an idea, and is consistent with things like Monster 3D boards that provide coprocessors to the "main" video card...
On the other hand, there's one notable fallacy here, which is that there is merit to moving to a system working with 128 bit memory space sizes. This is silly from at least three perspectives:
This is why the only systems that presently support more than 4GB of RAM on Linux are UltraSPARCs,
There is apparently a way to support a 64 bit data bus through a longer connector slot, but that does not make for a 128 bit extension.
Based on the rates of growth in the past, it seems reasonable to expect that 64 bit addressing will be adequate for all but highly unusual applications for the next ten to fifteen years.
And even then, it is reasonably likely that by that time, technology may have progressed back to using some of the memory segmentation technologies of the '60s ala MULTICS to obviate the need for linear growth of adddress space.
2^63 is approximately 4 billion billion, which is a very large value. A move to 128 bits squares that again, which provides an even more atrociously large space.
By moving to 128 bit addressing, the complexity of the memory addressing circuitry increases, as do the minimum amounts of memory that are likely to get addressed for instructions. This means that programs get bigger even if they do no more than they would on a 32 bit architecture.

The faster bus speed requires a cleaner eletrical enviroment the the lower bus speed. That is provided by the "Slot B" systems (shorter strighter traces I guess). Acording to AMD one could make a Slot A system that clean, but it isn't part of the Slot A specs AND costs more, so it is unlikely to be done on the Slot A systems.
My guess is you will see 2-way K7 systems, and 4-way K7 ultra systems, and later some 4-way K7's, but no 8-way or 16-way non Ultra systems. Of corse if there is a market for 8 and 16 way non-Ultra systems it doesn't look like AMD will stand in the way. It's not like the non-ultras were designed not to work in the SMP world, and it's not like the SMP chipset, or motherboards are made by AMD!!
Lastly when Intel first designed the Slot 1 vs. Slot 2 systems I thought that the PII Slot 1 module was too small to both hold the larger cache, and have enough extra cooling, which makes a real reason to have had Slot 2 in the first place. I assume that has gone away as SRAM tech has advanced.
SMP is not a panacea (Score:2)
First, a quick summary. SMP, or Symmetric Multi-Processor systems are so called because each processor is effectively equal to the other processors. There are a number of different architectures, either using clustering of procs sharing the same bus, or clusters sharing the same memory, or even clusters expanded out.
As a breakdown:
AMD SMP-to-be: processors in a 'cluster' share the same memory, I/O arbitrated by a complex chipset.
Intel SMP: up to four processors in a 'cluster' share the same bus, arbitrated by a complex bus protocol.
Beowulf - Each cluster has its own bus, I/O, but communication is much slower.
Now, one would think that performance would increase linearly for each CPU? So if you have two CPUs, your performance is 2X? Four, for 4X? Don't bet on it.
In every case, you have to factor in:
(1) SMP programming requires different algorithms to take advantage of multiple CPUs. Some tasks require too much communication, or are too linear to benefit much from having another processor. Remember that adage that you can't have a baby in one month by getting nine women pregnant!
(2) SMP split by 'thread' has limitations as well. Operating system complexity rises dramatically.. As far as I have read, the fined grained SMP necessary to make this work is still under development in all free operating systems. And this code is so complex and the tools to debug this sort of code are so expensive that it is likely to be quite some time. Linux is blessed that some large companies are contributing to the codebase for SMP support -- Intel among them if I recall. Other than operating system issues, this requires many of your programs be re-written to benefit (depending on what you want to do).
(3) In every case, there is a shared resource or cost. If every processor wants to access the memory, who "wins"? Likewise for the bus on the P6 SMP.
I've read numbers at one pointed that showed the most drop-off at four. I suspect that Intel, going for 'profitability', made four the maximum for many reasons based on simulations and probably electrical limitations.
As a final point, look at the Errata listings for Intel processors, now that they are public. Given that Intel has the resources to extensively test their processors, look at how many of these relate to having more than one processor communicating?
Now, consider that with your AMD SMP system, you have a chipset that has to handle complexities of multiple processors sharing resources, with less resources to figure out what could go wrong.
In this light, AMDs decision to focus on a single processor environment makes a huge amount of sense. If you get a huge boost out of parallelism, buy the cheapest Mhz/$ and Beowulf it!

Now this chip is expensive & probably needs a new MB to take advantage of it. This is an expensive upgrade - so who will go for it?
Intel is trying to make everyone to upgrade to a i820 motherboard and trying to make everyone switch to RAMBUS ram. Plus the new coppermine cpus aren't cheap either, so what's the difference between an Intel and an AMD upgrade?
Graphics / Video people? Nope these people are most likely to be looking at a G4 Mac or SGI these days. Or at least an x86 with history of good FPU performance (intel)
True, a G4 can outperform a K7 at the same clock rate, but G4s are not going to reach 700 Mhz anytime soon, so a K7-700 will be faster than a G4-450 even though the G4 has a better fpu. Also, I admit AMD has a history of poor FPU performance. But the K7 changes all that. In case you haven't looked at the benchmarks, A K7 is generally 5%-15% faster at every FPU benchmark out there {expect maybe the intel benchmarks =) }
Gamers? Nope, this is probably too expensive - and after the history of bad fpu and wierd incompatibilities / crash bugs that AMD has, I cant see gamers going for it.
Weird incompatibilities: All Windows require is a few extra drivers / patches to get things going. Installing them is pretty much the same as installing windows, you just keep on clicking NEXT and YES. In Linux, I have yet to see any problems with my K6-2. and crashes and bugs - It's the Intel CPUs that can't add correctly and has that weird F00F bug. AMD cpus ARE NOT cheap, crappy pieces of technology that will fail you and fry your computer. For gamers, those who are on a budget would probably go fora celeron, but those who want the best they can get - a K7-700 is it. Nothing intel makes (right now) can pump out as many FPS as a K7, just look at the benchmarks, K7s pretty much make every quake lamer drool and
Servers? I really can't see it. Intel are firmly established in the server space, and cant see that ending.
Well, AMD cpus do not have SMP capabilities yet, but as soon as that's developed, AMD cpus will (hopefully) be better. Afterall, they have a faster (200 Mhz, 400 Mhz), more advanced bus (EV6 vs GTL+), along with better cpus (700 Mhz + 128k L1 + up to 8 Meg L2 vs 600 Mhz + 32k L1 + up to 2 Meg L2).
Office workstations? Nope, they will continue to be mid ranged intel cheaps supplied in bulk by Compaq / IBM. There is no need for this power.
Right, and they don't need the latest PIII to "make their internet go faster" either. That's where the K6-2 and K6-3 comes in. K6-2s go up from 350 to 500 mhz and they are dirt cheap. K6-3s are way faster than celerons at interger (aka office) applications and they offer a decent performance / price ratio.
Consumer boxes? Nope too expensive.
Same for intel, their cpus are just as expensive.
Sure it's a nice bit of kit, but who exactly would buy one? The big manufacturers won't use them considering AMD's history of supply problems.
Well, when the K7 first came out, people couldn't by one because Compaq was buying up all the supplies... Who knows, maybe if AMD starts pumping out K7s... we'll see...

Yes! Bus speed is an issue, but the solution is non-trivial. Those lines on your motherboard have electrical characteristics, based on length and frequency. Simply put, they become radio-transmitters! Even the layout rules for the 100Mhz/133Mhz buses are tight.
Inside the chip, it's a lot easier to push frequency because your lengths are *very* short. Thus, it's likely that there will be consumer-level 1Ghz CPUs next year or so. But the bus speed is still down near 100Mhz (even if you try tricks like double pumping it).
One solution to this problem is to put more on the same chip. These systems on a chip have been created less than happily before, as you lose most upgradeability, *but* you get to use whatever bus speeds you want internally. You also save a few bucks, and a few inches.
If I had to guess (and my crystal ball is down for the RH 6.1 Upgrade ;) ), I'd think that as cpus become a commodity item, that systems on a chip will be more and more prevalent. I'd expect alliances between nVidia and 3DFX with the AMDs, VIAs, and even Intel (despite their snapping up Cirrus Logic).
Remember, though, that if your code fits in cache and takes advance of new hints for caching present in the K7/P3, you might not even notice the faster bus speed.
My wish for improving computer performance would not be a faster bus, faster clock speeds - it would be software:
An excellent optimizing compiler!

AMD's Athlon only services the high end of the market, and VIA's processors only service the low end. Right now, VIA makes the bulk of their moolah on chipsets, and Slot-A offers an immense opportunity for profit, an opportunity that their processors couldn't offer until at least a year from now, and even then I'm skeptical.

Switching to dual processors, however requires a new chipset and new motherboards. Currently AMD isn't making either. I believe, that a chipset manufacturer, could make a SMP chipset based on the specs that AMD has released thus far, if not, AMD could simply release more specs to permit it.
Since the chipset manufacturers aren't likely to make SMP chipsets until the Athlon is already sucessful, AMD will have to produce on themselves or wait a while. Designing the chipset would be expensive, and still won't sell until there are SMP boards.
Given that AMD is cash strapped as it is, and the vast majority of the market is for single processor systems, designing their own chipset would probably be a grave mistake. I personally think AMD is on the right track now, they just need motherboards for their current Athlons to proceed.

Then you fail to see why fast memory busses are expensive. It's much cheaper to take advantage of spatial and temporal locality of reference by using caches than to build a faster memory bus.
You'd pay about $10,000 and there would be no speedup. A single Pentium III/Athlon running at 600 Mhz would probably be faster. Why? Most (95+%) of all memory accesses are found in L1 or L2 cache.

Nope, the beowulf and first post things aren't going away -- let's lighten up a bit. If you don't like stupid comments, you can filter out most of the stale ones, and that takes care of most of the "problem".
Frankly, the long winded "informative/interesting/insightful" posts make me weary eyed most of the time. In my book, flames and trolls are much more interesting, especially the grains of truth that they sometimes work from.
Besides, it's Rob's fault for not including a "bad-attitude" option in the recent moderation roundup anyway -- lots of the flames and trolls wouldn't be anonymous if there was room made for them to be disagreeable and contrary without shame.

Hardware Performance Question.. (Score:4)
128meg ram, 16meg TNT, IDE.. yada yada..
At work I am running a PIII 500 with about the same setup.
this is my questions, why am I not seeing a near double in my performance? I would guess that it was ram.. BUT.. I took ram out of one of the other machines, and I am not seeing a GREAT performance increase..
Sure, my computer at work can crunch SETI@ blocks a bit quicker, but
QUICK NOTE: I am not a big gamer or 3D freak..
THIS IS THE POINT.. has anyone actually used a computer that goes that fast? (700 Mhz).. is it even worth it for the average LinuxNerd(TM)
It seems like these superfast CPU's are GREAT if you have VERY spacific needs.. (3D Rendering (ie. Games))
For someone out there that has a lot of experience with a lot of different CPU's, which CPU configuration is the price to performance ratio?
Will I see more performance increase by purchasing a UW/SCSI-Controller / HD????
More Ram?
More CPU?
:) For some reason I feel like if I dump my current motherboard and go purchase a AMD-700 w/new ram.. etc. I will be disapointed....

With CPU's, I think as emittance goes up (with freqency), power consumption may go quite a bit up. Also circuits and components on the CPU must be redesigned.
Now if your MOTHERBOARD were running at 1 GHz, it's be a different matter.

PC-133 support is important, but the AGP 4x currently is not.[snip]
Although there may not me much of a techical advantage in having 4x AGP, the fact that some graphics cards (Ultra TNT2, I belive) already support may encourage a lot of gamers to get them. Remember that some PC gamers stay at the top of the technology curve, at great expense.
It might nto have much of an impact on the market, but 4x AGP is a very marketable point, after all, it sounds a twice as fast as 2x AGP, and besides, it's the latest, greatest thing. (said in an entusiastic marketing droid voice)

At the resellers. It's the perfect upgrade to tout to those repeat customers who come in at every major CPU upgrade to buy yet another motherboard. Some people will buy whatever has the big numbers on it.
Unfortunatley that's not a sustainable market, nor will that sort of person be fooled more than a few times. So AMD is likely in deep trouble now with this.
The local shops here are already selling Athlons and motherboards, though I can't say I've heard how well they are selling. I bought my Pentium III a month ago so am not interested. And I regret ever buying a K6-2.

If Athlon wins, great. It is smart for AMD to have a plan B though.

Silly I know, but my point is that consumers can be trained to think anything is better if the advertising says it is. If they create some cute little "Puffy, the SMP doggy" all the JoeShmoes are gonna run out and ask for dual-processor systems at Circuit City and Best Buy.
Tell them they need two processors so one can access the Internet and the other can play games, or better yet...tell them they need a processor for every application they want to run. That outta put consumer demand for SMP on the laps of those boys in marketting...

Humans invented the term microwave... there is nothing different about it other than the period of the generated wave. Will it fry you is what you really want to know. The fact is any electomagnetic energy can fry you. It's a function of how much energy is output, how far you are from it, and how long you are exposed. Faster period means more energy, yes, but the fact that it is 1GHZ as ooposed to 700 Mhz doesn't mean as much as where the source is, what's between you and it, how far you are from it, and how long you stay there.

Now this chip is expensive & probably needs a new MB to take advantage of it. This is an expensive upgrade - so who will go for it?
Graphics / Video people? Nope these people are most likely to be looking at a G4 Mac or SGI these days. Or at least an x86 with history of good FPU performance (intel)
Gamers? Nope, this is probably too expensive - and after the history of bad fpu and wierd incompatibilities / crash bugs that AMD has, I cant see gamers going for it.
Servers? I really can't see it. Intel are firmly established in the server space, and cant see that ending.
Office workstations? Nope, they will continue to be mid ranged intel cheaps supplied in bulk by Compaq / IBM. There is no need for this power.
Consumer boxes? Nope too expensive.
Sure it's a nice bit of kit, but who exactly would buy one? The big manufacturers won't use them considering AMD's history of supply problems.
