Cyrix tried the exact same thing a few years back (marking a chip with a model number that represented the 'approximate intel performance' rather than the chip speed itself.

This isn't trickery, it's consumer educating. Back in the days of Cyrix, MHZ ment a lot more, and Cyrix was a lot less realistic than AMD is being. AMD could safely call their 1.53Ghz chip the 2000+ instead of the 1800+. With a combination of a conservative "ratin" and a very well performing chip, I think AMD will be successful with their new offering.

It's also worth noting that this is only a temporary solution. I believe AMD is working on a completely new rating system to be adopted in 2002. It should completely abandon MHz measurements and evaluate performance more effectively. Whether or not the industry will cooperate is yet to be seen.

Silly silly question time:

You have 2 competetors, really. The underdawg is going to try to make a new rating system that they hope to get everyone to use to bring back "fairness" to the processor rating game, but when your only real competetor is the one who is going to loose bigtime by using this new system (and therefore they will not), then how do you expect this new rating system to work?

I think what would be better is for now to drop this silly "we're as good as that P4, swear it!" scheme and just call it something else. Call it the AthlonXP G+ or 6P+ or something. That way there is no realative comparison, and when you go to the store to ask "hey, which is better here?" the guy can just tell you "Go with the AMD such and such, because it's as good as this P4 over here", not only does it stay up to date with comparisons, but you also don't get accused of trickery.

No, calling it the 2000+ would be a horrible idea right now, and they did the right thing to be conservative, because as the article stated, once the P4s come out with their new core then the comparisons will be much more accurate. If they overjumped now and then the 2000 was only as good as a 1800 MHz P4, then you'd have even MORE trouble on AMD's hands then they would have had before they started this.

This is AMD marketing trickery countering Intel engineering trickery. Intel doubled the pipeline length in the P4 versus the P3 and Athlon (20 stage versus 10 and 11, respectively) in order to crank the clock speed at the expense of performence (see The Megahertz Myth [apple.com] for an excellent overview on the subject). Thus why a 1.13GHz P3 will outrun a 1.4GHz P4 most of the time, and why the upgraded core of the 1.53GHz Athlon XP outruns the 2GHz P4 most of the time (for half the price).

In other words, in marketing, two wrongs make a right!

It's not marketing. It's a design decision which also happens to have nice marketing side-effects. Higher clock rates versus a shorter pipeline is just a tradeoff much like CISC versus RISC. Intel's designers felt they could get more total performance out of the processor by lengthening the pipeline so they could clock the processors higher. If it also sounds faster to the consumer, so much the better.
• #### Re:will the trickery work? (Score:2)

Yes, that is a VERY good point that I wish that more people would realize.

The fact was that for a while there Intel did have the fastest chip out on the market, and AMD is constantly playing the catchup game. In another month Intel will release their newest chip, and they will have the lead as the "fastest chip" on the market.

So whilst all of the AMD affectionatos are trying to proove that "MHz aren't everything! (It's not the size that counts!...)" that door swings both ways there... AMD is still playing catchup for fastest chip, and Intel is still in the lead. (Yes yes the newest AMDs are faster than the P4 2.0, but not for long).

HOWEVER, AMD does have one huge advantage : price. That one is a little hard to dispute, and is why my last PC purchase was a nice TBird 1.4 rather than an Intel at significantly more price. However if I was going for a once you factor in the cost of the motherboards. If you go for good motherboards, the Intel ones are cheaper and thus offset the price difference between chips. But as soon as you leave the Celerys behind then AMD is a clear winner, if not having the fastest chip (which doesn't really mean much since who really buys the fastest chip out anyways?) then all of their chip/mobo solutions are 2/3rds of the price for about the same performace.

Oh well. Too bad Intel got gipped with the Rambus scandal. Mind you, it's not the RDRAM technology that's inherently bad, but more of the company. Interesting parallels between the RDRAM technology and Intel vs AMD and SDRAM if you ask me =)

The "proper" way to compare processors would be to use the SPEC benchmarks (http://spec.org) (since they are supposed to "define" processor performance). However, AMD won't use these benchmarks use them. If we look at the highest published scores from AMD we see

Integer: 495 base, 554 peak
FP: 426 base, 458 peak

For P4

Integer: 640 base, 656 peak
FP: 704 base, 714 peak

The athlon was Advanced Micro Devic Gigabyte GA-7DX Motherboard, 1.4GHz 1 cpu
The P4 was Intel Corporation Intel D850GB motherboard (2.0 GHz, Pentium 4 processor) 1 cpu

Obviously, this isn't a totally fair match (this is the most recent numbers I could find from both on this page http://www.spec.org/osg/cpu2000/results/cpu2000.ht ml) (there is no CPU2001 benchmarks... we'll probably stick with CPU2000 until 2005 or so... we stuck with the SPEC95 benchmarks for 5 years). The newer althonxps will have improved numbers, but the 1.4ghz part was beaten pretty badly (and those numbers came from AMD themselves, so their setup was optimal in their eyes).

This is actually a pretty awful way to measure the performance of a CPU since it's _highly_ dependent on aspects of the motherboard. The German magazine c't did a test of the Athlon XP CPU recently and tested on two different motherboards (Gigabyte and Asus, I think) - the spec scores different wildly! Neither board tested used the VIA KT266A chipset, which is known to be the fastest (in some cases, by far) of the Athlon-supporting chipsets.

So, that test proves to NOT be a test of CPU, but of the CPU/chipset/RAM/motherboard combination, which is hardly the same thing.
• #### Re:Model Numbers (Score:2, Insightful)

It may be highly dependent on the motherboard, but I hardly see that as a reason to invalidate SPEC as a benchmark suite. One of Intel's advantages to this point has been the performance of the motherboards they create. Who really cares if the AMD processor is faster 'on paper' but in any real machine it will be slower?

If AMD doesn't like the numbers, they're going to have to bite the bullet and publish some numbers using a nonAMD motherboard. The fact of the matter is that SPEC is still the most widely industry recognized and accepted benchmark suite.

The reason I thing SPEC is a good measure (even allowing for the issue you raised) is because the vendor has complete control over the numbers he publishes--he gets to use his choice of hardware, his compiler etc. We don't have any of these complaints that Oh quake 3 wasn't fairly optimized etc.

Just my opinion I suppose, and I do acknowledge the large number of data streaming floating point benchmarks is going to give a processor using RDRAM and advantage, but that's just life.

Well, just because the SPEC tests are awful for CPU performance measurement, doesn't mean there's any single test that's good. :)

I think the only _real_ test of performance is a comprehensive set of real-world (read here: real applications!) tests. That, too, is not a test of _just_ the CPU's performance. I don't know how you'd be able to accomplish that, aside from spouting off some simulated results.

Unfortunately for the consumer, it's not possible to translate real-world performance results into a magic number that they can quickly or easily read to see how fast a system is. That's just life. People need to do research on things. Most people wouldn't be able to tell the speed difference between a 1gHz Athlon and a 2gHz Pentium IV system, anyway, so the point is moot for most people. Those of us who care about such things know where to go and what to look for when researching a computer purchase.

For full systems, a SPEC score might make a small amount of sense - then Dell could advertise their SPEC scores for each system, Gateway could for theirs, etc. But for those of us who buy on a component level, it makes no sense at all. The KT266A motherboard speed improvements over the AMD 760 chipset will probably offset those SPEC scores and let them Athlon XP 1800+ come out on top of the Pentium IV 2gHz CPU. (at least until Northwood comes out).

I guess my main gripe is that SPEC is being bandied about (even by the CPU manufacturers) as a measurement of pure CPU performance, when clearly, it is not. It's unfortunate AMD chose to publish their scores on a platform that's not the fastest. *shrug*

I'm really waiting for a DDR333 Athlon platform to come out next year. Hopefully there'll be a VIA KT333 chipset and also hopefully the Athlon 'Barton' (0.13micron Athlon platform) will have a 333mHz DDR FSB to mate to it. I've got other purchases in mind until then, assuming I ever get enough money to make them in the firstp lace.

Even SPEC is too easy to manipulate, and too far from what most users do. The only real way to benchmark a processor is by testing it with what you do the most.

For tech-savvy users that might actually notice the speed difference, this means we have to browse the benchmarks at Anandtech, etc., and it's usually pretty easy to find a benchmark for an app identical or similar to what you spend most of your time doing (i.e. Tribes 2).

Of course, it's likely that none of us would notice the speed difference between a P4 2.0GHz or AMD 1800+ in whatever app we're using; and it's certain that a non-power user wouldn't. Which is fine, because the non-geek isn't going to read all the benchmarks.

Chip still runs on a clock, so what?

No, clock cycles do not mean anything about performance to "some talented computer users." Here's why, using CPUs other than AthlonXP and Pentium4 so as not to inflame anyone:

The old Intel 8-bit CPU used in PC/XT machines ran at 4.77 MHz (4,770,000 clock cycles per second) but this does *not* mean that it could do 4,770,000 *things* per second, because each time it needed to execute an instruction, it took several (i.e. more than one) clock cycles to do so. Furthermore, the largest numbers it could operate on natively were generally 8-bits long -- a 32-bit calculation, for example, required user code to complete, which of course meant many, many more cycles.

The Hitachi 6309 CPU of the same time period, by comparison, ran at 2.0 MHz (2,000,000 cycles per second), but was **MUCH** faster for the same types of tasks than the Intel 8-bit CPU because it could *often* finish a complete instruction in only one clock cycle and because it had 16-bit registers and a 32-bit register and could thus do MANY types of math *natively*, in just one or several cycles, that the Intel CPU needed user code (and thus, hundreds or thousands of cycles) to complete.

Because of these types of _architectural_ differences, clock cycles have little or nothing to do with the real speeds of different chips performing real-world tasks (which, for gamers, includes things like Quake 3). In fact, clock cycles and MHz are *the same thing*, as MHz on a CPU simply means "number, in millions, of cycles per second."

You will find no statistical correlation between the *actual* clock speed on an AthlonXP and each of the benchmarks vs., say, a Pentium4 at 1800 MHz. Yes, one is running at ~1,500,000,000 cycles/second and one is running at ~1,800,000,000 cycles per second, but that doesn't tell you how many cycles each one is spending doing different types of tasks or (as is often the case) sitting around waiting for data from the rest of the system or from the bus.

Its very sad but AMD is essentially admitting through their marketing ploy that the average consumer is incapable of realizing that the speed of a processor and indeed a system is more than a clock frequency.

Although virtually every reviewer pans the confusing processor labelling, I believe that it was a good business decision. With the success of the Athlon processor, AMD went a long way towards minimizing the marketing impact of "Intel Inside". Now they find themselves "burdened" with a processor which out performs its competitors significantly at a given clock speed. If they label the chip with its clock frequency they invite price comparisons to similarly clocked (but underperforming) Intel products.

I think the new labelling scheme is actually a win for AMD. Smart consumers will buy the chips because of their superior performance, regardless of the name. "Joe 6 pack" will buy it because he can buy the AMD 1700+ system for less than the Intel 1600.

Has anyone heard whether or not AMD's heat problem has been solved? Reading Tom's article on what happens if your heat sink falls off really put a kink in my AMD-buying choice. I mean, it wasn't even like you had time to hit your power button - you went from 'snap' to 'smoke coming from case' in less than a second.

No matter how much faster and cheaper they are then Intel, that's a HUGE risk to take on your system.

Umm...if you're heat sink falls off, you have one of the following problems:

You're and idiot and installed it wrong in the first place.

You're system vendor is an idiot and installed it worng in the first place.

You're motherboard is made of cheap materals

You forced something didn't you (see 1)

There is no good reason for your heat sink to just fall off.

The whole "Tom's article on the heat sink falling off" bullshit is silly. If the water pump in your car fails and you keep running it then your motor will burn up. Luckily we have temperatore gauges [livewiredev.com] on most autos to let us know when our car is overheating.

AMD CPU's, for the most part, kick mule all over Intel's offerings at the same rated speed. If you follow normal precautions with your CPU (i.e. fasten the heatsink properly) the likelihood of the heatsink "falling off" is next to nil.

Well, a car engine will take at least a couple of minutes to go from cooling failure to overheat to physical damage.

Your car's engine won't burn up in a couple of seconds like an AMD processor will.

With a car, you have time to pull over and shut down the engine. With an AMD, even the fastest temperature sensing system won't be able to detect it and remove power in time. Even if you knew instantly when your heat sink failed, the combination your reaction time and the delay between pressing the power button and dropping of the power supply voltage to zero would be enough time for your CPU to burn.

As for a motherboard temperature monitor, most can only poll every 1.5 seconds or so (HW limitation). That doesn't leave enough time between when the cooling fails and when the power gets cut off. Remember also, that monitoring software and the power off BIOS calls take time, and there is also a delay between the power off bit on the MB being toggled and the power from the power supply dropping to zero.

What do you think will happen if your Intel heat sink will fall off?

My motherboard will shut off if the fan dies(far more likely then your heatsink falls off) and I run soft ware that alerts me if the CPU reaches a certian temperature. It can also close down my system if I want it to.
these two precautions need to be taken with any modern system regardless of manufacturer>

FYI. My athlon 1.4 runs at 40c with the heat sinkan fan, and is rated above 90c.

Wow, if my heatsink fell off, it would fall directly on, and likely short out, my video card - which costs as much or more than my processor.

Cyrix used to sell their processors with a PR-rating. PR150 which tried to compete with a Pentium 150, was actually a lower MHz.

The difference in the policy is that the Cyrix PR150 was only in _some_ applications the equal of a Pentium 150, at others (gaming) it was truly pathetic.
The AMD Athlon XP 1800+ is in almost every regard better than Pentium IV.

The conclusion is that, even though I wish AMD would market their processors on MHz, they are actually not overhyping their processors when stating in this marketing, like Cyrix did.

Two cars are in a race. The Blue Car has a 6-cylinder engine while the Green Car has a 9-cylinder engine. While the Blue Car s engine works hard in terms of high RPMs, it doesn't actually go all that fast down the road. In contrast, the Green Car s more powerful engine doesn't have to run at high RPMs. Yet on the road, the Green Car blows the doors off the Blue Car. The more powerful Green Car engine is designed to run efficiently and to deliver a faster, more powerful driving experience.

Im waiting for the MP version of the AMDXP chipset. After they come out with thier 2000+ procs, im upgrading from my dual P3-800. SMP is the only boxes I want to use now, going from 1ghz to a dual 800, my system doesnt hang when an application use all the cpu resources.

I just wish I could pick up a cheap powerpc atx motherboard, and through a couple power4's in it. But for some reason IBM/Motorola doesnt want to compete against Intel in the desktop market, im denied the joy of a smp box. I have been toying with the idea of picking up an SMP Mac now that OSX is patched and running smoothly.

Speaking of PowerPC chips, Recently /. had a nice article on the Power4 [slashdot.org] cpu with 2 processor cores.

The previously released Athlon MP is the multiprocessor certified version of the Athlon XP. Faster versions of the Athlon MP are expected to be announced next week, with new dual processor motherboards (in addition to the Tyan Thunder and Tiger MP boards already on the market) expected next month.

The Athlon4 notebook CPUs are also equivalent to the Athlon XP desktop CPUs (with the addition of PowerNOW! power management, natch). As notebook and MP-certified CPUs are higher margin parts than uniprocessor desktop CPUs and AMD had no previous MP or notebook Athlon offerings, AMD directed their new Palamino-core fabrication lines to those markets first.

We know that marketing your product based on MHZ alone will kill it. This was seen right from the early days of the 386's. People looked at the generation of chip and the equivalent clock speed. Teck people would ignore this ask they knew real benchmarket would tell the truth.

Look at recient times, you have a bigger gap in this problem. The G3's and G4's are clocked between 400mhz and 800mhz, but people are put off buying one cause they can get a PC with 1.2Ghz for cheaper. The G4 can be a faster chip with lower clockspeeds but people won't buy it cause all they see is 800mhz vs 1.2ghz. The bigger number in compters means it's better, everyone knows that!

If AMD doesn't start PR rating their chips people won't buy them. They are slower and cheaper (in the mind of Joe Sixpack) so they must not be as good as an Intel.

This is my new proposal to incorporate all the factors of a microprocessor into its product name, thus giving a more accurate and precise measure of its speed.
Multiply all the frequencies together you can think of, i.e. 133mhz ram * 2x(ddr) * 6x clock multiplier * 266mhz FSB = Athlon 371868. If more marketing is desired, use pretend scientific notation. 37186800000000 * 10^(-8).
• #### AthlonXP 1800+ != 1.8 GHz P4 (Score:2)

Instead, AthlonXP1800+ == theoretical 1.8 GHz Athlon Thunderbird

(As measured by some suite of benchmarks AMD has put together, although it's not exactly clear what because they keep fouling it up and talking about the P4 in their so-called whitepaper [amd.com]).

Thus, while this may be a misguided marketing ploy destined to backfire, it is nonetheless a fundamentally fair one, strictly meant to compare Athlons to Athlons, not Athlon's to P4s!

"Model numbers are designed to communicate the relative application performance among the various AMD Athlon XP processors, as well as communicate the architectural superiority over existing AMD Athlon processors." (From the FAQ [amd.com].)

Thus an AthlonXP 1800+ is (supposed to be) just as much better than a 1.8 GHz P4 as a 1.4 GHz Athlon Thunderbird was better than a 1.4 GHz P4.

(In reality this is not always so much the case, the main reason being that at higher processor speeds the chipset comes into play more, and the dual-channel RDRAM i850 for the P4 delivers more bandwidth than a single-channel PC266 chipset for the AthlonXP (eg. VIA KT266A). This advantage will be all-but-gone once PC333 chipsets hit in a few months...)

• #### One more thing (Score:2)

Everyone and their mom is comparing this to the old PR performance ratings employed by Cyrix et. al. and what a big ripoff they were, and how everyone caught on and Cyrix went out of business and so on. There are two problems with this:

1. PR was a terrible benchmark. It was proprietary, synthetic, had little to do with real-world applications. Moreover, it was integer-only, and thus rather neatly covered up the fact that while the Cyrix CPUs were indeed faster clock-for-clock than a Pentium on integer programs, their floating point seriously sucked. In contrast, the suite of benchmarking suites AMD is using is well chosen, all based on "real-world" application benchmarks, and covers most problem domains pretty well.

The only missing component which might be interesting to have included is SPEC, but the only new data that would really provide is how well cutting-edge, mainly-experimental compilers support each processor. On the one hand, this exclusion does tend to disadvantage the P4, since modern compilation techniques are important to top P4 performance, and eventually these techniques will make their way to mainstream precompiled applications. On the other hand, for the next couple years or so 99% of the programs consumers run will still be compiled with not-so-modern compilers (i.e. MSVC++), and as Intel now owns every single important compiler research team in the world, they may have a slightly unfair advantage here.

In any case, this doesn't really matter because the AthlonXP rating system is comparing AthlonXPs to Athlon Thunderbirds, not P4s.

2. PR meant "Pentium Rating", even while Intel was selling "Pentium-II"s. This is the big thing people tend to forget about the whole PR thing: it was more or less accurate (integer only, of course), but the problem was that Cyrix was trying to position a "PR250" chip against, say, a PII-266. Great, except that the PII was significantly faster clock-for-clock than the Pentium was, especially running 32-bit apps (eg. the then-newly-standard Win95). The PR thing *was* a scam, not because performance ratings are innately a scam, but because the "P" in PR confused the fact that the comparison was to an obsolete processor and not to the current competition.

In any case, this doesn't really matter because the AthlonXP rating system is comparing AthlonXPs to Athlon Thunderbirds, not P4s.
