Athlon 64 3400+ Reviewed 245

Posted by CmdrTaco from the upping-the-ante dept.
SpinnerBait writes "Unlike the Athlon 64 FX-51, this new 3400+ rated Processor, has a 64 bit memory interface, with its integrated memory controller, drops in at several hundred dollars less than an FX-51 and is also clocked at 2.2GHz. It gives a P4 3.2GHz Canterwood based machine a run for its money too, as this review with benchmarks at HotHardware reports. And where is Prescott? Fortunately for AMD, it's a bit tardy to market and this will give this new Athlon 64 speed bin time to take a firm hold."

      What's a speed bin?

      In case you're not trolling, chip manufacturers crank out one design of chip, test it, then put them into bins based on how fast they can run reliably. They probably don't actually use plastic bins, but you get the idea.

      Thus, a "speed bin" - a lot of chips designated to run at a certain speed, despite the fact that it's the same design and metal as a chip designated to run at a slower speed.

      Due to minor process variations (random faults in materials, equipment, background radiation etc.) every manufactured chip is different. Some chips work fine at higher speeds, some chips only work properly at lower speeds, some chips fail to work at all. Since these microprocessors are at the cutting edge of silicon process technology, the variation matters. Now, to sort out which chip works at which clock speed, the manufacturer has to test every chip and classify them accordingly. Some are sold as 2 GHz chips, some are sold as 1.8 GHz chips, and so on. These different grades are called "speed bins".

        It is not uncommon to use a Peltier Effect cooler. This is basically a huge stack of thermocouples run in reverse. You put in a lot of current at low voltage, and it produces a temperature differential. If you heatsink the "hot" side to ambient air, the "cold" side may be well below zero. But, it is not very efficient (like all cooling systems), so you need to put in several times as many watts as it extracts from its "cold" side, and not surprisingly the total of both appears at the "hot" side, so you may need a very big heatsink with powerful fans.

        I don't have the numbers in front of me right now, but at a guess you would need 300 watts to cool a 100 watt CPU, so would need to dissiapte 400 watts to air.

        It is inadvisable to make any attempt to get the chip below zero, obviously ice formation will happen, and when you switch off, it will melt. Should you switch on again, disaster is quite probable, unless the PCB had a good conformal coating and the socket has an interfacial seal. The conformal coating can be dealt with quite easily, but I have never seen a sealed CPU socket. BTW I usually work as an avionics designer, where we have to make things that will run from well below zero to well above, so I do know the problems.

        Another issue is thermal fatigue. The temperature coefficient of expansion of silicon does not exactly match that of the (probably epoxy) package, every temperature cycle causes a stress cycle, which causes a strain cycle, until something breaks. Same for the motherboard itself of course, if you should cool the whole thing. That is also a good reason to never overclock anything, apart from the possibility of getting subtle data errors and increasingly buggy OS as a result of inadequate timing margins, you will definitely wear the thing out a lot quicker. Every 10 deg C roughly halves the life, or the number of on/off cycles it will survive, and if you do the calculations, the numbers are quite depressing for a modern PC.

        If you really want a thumping great 64 bit processor (I certainly do, when the price comes down!), it would be best to calculate the cooling system, and maybe do some tests with thermocouples etc, to try to get the CPU chip to settle down at a relatively safe temperature, say 40 deg C, without getting ice formation on the coldest parts. The clever bit would be to get it to power on and off without any excursions below room temperature (often 20 deg C) or above 40 deg C. Heat soak when you switch off the CPU would be minimal, the mass of the chip itself is very small, but cold soak from a huge peltier block could be a problem, the CPU could be dragged down to -40 deg when you switch off, which is exactly what you don't need, for a long and reliable life.

        The other thing to watch out for is that at low temperature the CPU internals will be out of spec. It is actually possible to get excessive current flow in some transistors, and local hot spots, because it is too cold. There may also be timing problems, data corruption, ...... It is not possible to test properly that these things are not happening. It takes a smallish time to fully exercise an 8-bit processor to verify all possible data and instruction operations, but somewhere near the lifetime of the universe to do the same for 16 bits. Throw in onboard cache, 64 bits, etc, and it is just impossible. These things work statistically, AMD know how timing variations, for example, might vary across the chip, and allow sufficient margin, within the published clock frequency and temperature range, but deviate from these ratings and this is no longer true. If running at 1GHz, a 1 in 10e12 error rate would corrupt your data or OS code within 1000 seconds, just over 1/4 hour. The error rate required to run an OS for weeks at a time at several GHz defies all attempts at testing. Again, a very good deterrent to overclocking (BTW my non-overclocked ancient K6-350 had a meltdown due to fan failure, and as it died the corrupt Win XP blew away all the passwords so when I got a new CPU and fan, any of th

      Apple proposes: "Packaging your Optimizations:

      Code that has been optimized for the G5 by simple re-compilation will run without penalty on a G4. If you have done more in-depth, G5-specific tuning (levels 1, 2 and 3) then you will in all likelihood want to provide a separate binary. In extreme cases, you may decide that you need only offer one version of your software that runs on Power Mac G5 computers only. However, you'll probably want to support most or all of the Macintosh product line, which means that you need to decide how best to deliver the right code to each of your customers. There are several ways to achieve this; the first is:

      Create different versions of your software for each processor that you support. This requires that you maintain three parallel code bases, something you may not want to do.

      It is possible for your software to query the computer on which it is running to see which processor-related features are available. You can design your software to isolate processor-dependent code and call the appropriate version as needed. This leads to two additional strategies for packaging your application:

      For every function that calls processor-dependent binary code, have your code call the appropriate version. If such functions are needed frequently, using this approach may decrease execution speed and make your source code (cluttered with if...then constructs) less readable.

      Isolate processor-specific functions into frameworks or shared libraries, then have your software load the appropriate version when it starts up. This enables you to write your main code without wrapping function calls in if...then constructs."

(The code will likely need porting to 64-bit anyway, especially by average Windows programmers who've never had to worry about different CPU architectures before.)

  • Video encoding? (Score:5, Interesting)

    Have anyone tried to encode xvid with one of these in 32 and 64 bit, preferebly using Linux? Is there much difference in speed? I'm looking at the 3000+ part as it is cheap but there are zero and none benchmarks to back it up in 64 bit mode.
    • Could one assume that Xvid benchmarks would scale along aside the DivX benchmarks that are included with the artical? I know its not the same but it would be a good place to start.
  • They mainly focused on the price/performance ratio as it is truely a killer to everything out there.

    Basically, they are predicting the death of the AMD FX51 as the 3400+ has equal or better performance and MUCH cheaper.

    Please add links to any reviews that run 64-bit linux (or other 64-bit OS of choice) with 64-bit benchmarks on said processor:

    Guys we have all the reviews listed on our main page [amdzone.com], and I'm adding more as they come in. It currently totals at 19. Does Hothardware pay Slashdot for these links? ;)

    • Damn, you posted something that doesn't bash intel and/or apple.

      I am in complete and total shock.

      For those that do not know, AMDZONE used to be a great site for info on AMD. In the past 3-6 months it has become a bash Intel/Apple site.

      Note. I am typing this from a dual athlon, and most of the other systems in my lab are AMD based. So do not call me an Intel/Apple fanboy.e

  • Fair Comparisons? (Score:3, Informative)

    If they are comparing the $700 [newegg.com] AMD 64-FX chip, they should be comparing it to Pentium's $1000 [newegg.com] P4 3.2 EE chip, not their sub-$400 P4 3.2.

    Also does anyone have an idea how expensive the AMD 3400+ chips are? Because the AMD 3200+ chips are $400 [newegg.com] retail. The article quoted a price for a thousand quantities but I was wondering how much it would cost for just one. Because if its pricey enough the P4 3.2 may beat out the 3400+ dollar for dollar.

    Though Intel doesn't have to really worry about that title. At $164 [newegg.com] the Pentium P4C smokes the pants off any AMD processor in its price range. At least, after overclocking it to 3 GHz, which is very doable even with standard cooling.

    • Check out the anandtech article [anandtech.com] from several posts above.

      It's compare there to the EE chip. I believe that I remember hearing that the price for the 3400 is less then the FX chip and out performs it as well.

      Will it really be cheaper and faster when you have to buy a new one every 6-12 months because you destroy it?

        Indeed the word "overclock" has become my hardware review spam filter; it has a strong "cold fusion" connotation. If I drop $700 on a CPU, I will not be running it out of spec in any way. If I'm that hungry for speed, I'll build a cluster.

        I can understand people wanting to overclock, say, a P-III 933 to see how far they can push it, but I just don't get the fanboy fascination with extreme cooling, adding a few megahertz, etc. Reading this stuff in a tech article is like finding an article on adding a whaletail to a ricer in Car&Driver - it just doesn't belong in a serious text.

        • You are obviously not a hardware enthusiast (this may sound like a flame but i just feel too strongly about this)... You can easily overclock for economical reasons without sacrificing cpu life. I've done this for years and continue to do so. As long as you know what your doing and have proper data from research (from reviews like this)you can take a sub $100 dollar processor and have it run like one for over $400 for years). The best part is that if you have the right components and you know how to tune
        • BTW, my cooling wasn't extreme... just a very large heatsink with good a large surface area and a 90mm fan (the larger the fan the lesser the rpms needed to move air and the lower the noise). Simply air cooling not water, peltier, or phase change... 50 % faster about 15 degrees cooler then most processors running on spec (the heatsinks amd ships are extremely weak... this is one thing intel has them totally beat at) as far as amd goes.
    • In lots of 1000 [amd.com]:
      Athlon 64 FX-51: $733
      Athlon 64 3400+: $417
      Athlon 64 3200+: $278

      So retail using your $400/3200+ as mark-up ratio, that should be something like $1040, $600 and $400, respectively.

      Also, on the P4/Athlon war I haven't checked lately since I'm happy with the XP2000+ I have, but at the price range I've been at AMD has come out on top for my last three processors (Duron 700, Athlon 1200 and the above mentioned XP2000+). Maybe the P4C is different, right now I really don't care though :)

  • What's the point without 64-bit OS and apps? (Score:3, Insightful)

    The main point of the Athlon 64 and Opteron is that they are 64-bit CPUs that can run 64-bit applications.

    The fact that they can run 32-bit apps under a 32-bit OS at pretty much the same speed as a 32-bit CPU is surely a huge yawn (but great for backward compatability.)

    Has anyone seen any comparative benchmarks under a 64-bit Linux system?

    I wouldn't be too surprised if AMD chose to withhold faster versions of the Athlon64 FX-series until any Prescott is just about to be released. A day before or so. Leap-frogging at its finest.

    Well, in all my testing of running 16 bit apps, a Pentium I outran a similarly clocked P4 by a healthy margin - so obviously the Pentium is a better chip, right?
    </sarcasm>

    Seriously - For a period of time the A64 will be running mostly 32 bit apps (at least in the Windows world), and so it is fair to benchmark its performance against 32 bit apps. But I cannot help but wonder how much P4 tweaking all those apps had, and how much A64 tweaking they did not have.

    Also, the memory performance tests are, to my mind, somewhat questionable as well, as different CPUs even within the Pentium line have different memory access behavior - code that will be bus limited on a P4 might not be bus limited on a P3.

    I am not saying the comparisons are not useful, but I am saying that they don't tell the whole story. Let us see some benchmarks wherein the A64 is running code that is written for the A64 - using the extra registers and so on.

    The reviews are all the same--run various permutations of the PC through benchmarks, and display the results using bar charts. And not just any bar charts. Use a gradient to color the bar, so that the color legend is rendered useless.

    The reviewers should read Tufte, and figure out a more effective way of illustrating their analyses than endless pages of bar charts. Oh wait, that's how they get their ad revenue. Never mind.
