Model Numbers Help and Confuse

We've chastised AMD in the past for insisting on a model numbering system instead of just reporting actual clock speeds, but for the first time ever, AMD's model numbering system makes a lot more sense than this drivel that Intel has been using to name their LGA-775 Pentium 4s. We get more complaints today from Intel's model numbering system than we've ever had about any other CPU model numbering system in AnandTech history; that includes attempts from AMD and Cyrix to do the same. While this could be too many users used to referring to CPUs by their clock speeds, it is definitely a present day issue.

Here's a quick recap of what Intel's model numbers mean as we're featuring all LGA-775 chips in this review:

CPU Name - Clock Speed - L2 Cache

Pentium 4 560 - 3.6GHz - 1MB
Pentium 4 550 - 3.4GHz - 1MB
Pentium 4 540 - 3.2GHz - 1MB
Pentium 4 530 - 3.0GHz - 1MB

AMD does have an interesting case for model numbers today; with the release of the Athlon 64 4000+ AMD has a total of five 2.4GHz CPUs in their Athlon 64 line:

CPU Name - Clock Speed - L2 Cache - Memory Interface

Athlon 64 4000+ - 2.4GHz - 1MB - 128-bit
Athlon 64 3800+ - 2.4GHz - 512KB - 128-bit
Athlon 64 3700+ - 2.4GHz - 1MB - 64-bit
Athlon 64 3400+ - 2.4GHz - 512KB - 64-bit
Athlon 64 FX-53 - 2.4GHz - 1MB - 128-bit

This is a prime example of where the model numbering system can actually help, differentiating between the three chips, but we also have to make sure to keep AMD honest in their ratings, which is one area we'll be investigating in this review.

    Fantastic article, obviously very well thought out.

    I would have liked to see a comparison between the 4000+ and the "real" FX-53 to really back up your rebadging theory (yeah I know speed+cache+memory width are equal between the two, but just to make sure AMD isn't pulling some magic out of there butt somewhere else).

    Yes, thanks for the XP comparison. I find it interesting how its not performing as well as it used to in games. (doom 3, farcry, cs:s)

    Also, your ut2k4 benches seem off. How is doom 3 pulling 50% more frames at the same res? Maybe your ut is at 16x12? I pull similar frames on ut w/ my 9800p oced.

    I like the ending... It sounds mysterious!

    I will suggest again to include some Ulead Video Studio 8.0 benchmarks for video encoding. Ulead is by far the fastest consumer grade video editor / renderer, it is the most complete and one of the most popular. In fact, it is almost 50% faster than Pinnacle 9, and almost 100% faster than videowave.

    Roxio has really been working with Intel as all previous version of video wave ran better on AMD hardware. As reference, results video wave 6 or 7 would be interesting. Newer doesn't always mean better, as you can see from Adobe Premiere. Version 7.0 is quite slower than 6.5 doing the exact same thing in the same platform.

    For DivX encoding, a run with virtualdub/virtualdubmod or DVD2AVI would be nice, as they are very fast and extensively used.

    Thank you thank you thank you for including an Athlon XP.

    This allows me to better judge where my current Barton 2.4 Ghz sits. ;P So I know when an upgrade to the next cheap overclocker will give a good enough performance boost to be worth the money.

    Here's an idea to play with: how about some 2D scatter plots of Performance/£ and Performance/Watt? Obviously not on everything - that would clutter it - but perhaps on one or two key things it'd be nice to see.

    EDIT #22 There is no 3400+ for SK 939 only 3500+

    Nice article BUT:
    You should make C&C power consumption and temperature
    Also some OC tests.

    The Battle for Value is not correct:
    1º WHAT about price of DDR1 VS DDR2?!
    2º MB for INTEL are more expensive, ~40€ is a great difference in a MB price.
    3º 0.09 AMD are just introduced so they are going to come down, not much but they are.

    In order to be fair you should compare with AMD 3400+
    AMD as a clear winner here.

    power consumption at idle - is this with or without cool 'n' quiet (I suspect without)?
  • Uff - Tuesday, October 19, 2004 - link

    I have to agree with #18 - it's not worth paying more than twice the price of a 3400+ just to get 3800+ on 939 platform.

    Many say 'OH! But s939 is more upgradable!', but if you think about it, by the time you upgrade next there are very likely going to be new motherboards available aswell and you end up upgrading that anyway. Not to mention motherboards cost virtually nothing compared to cpus.
