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.

    Splendid reading! This site is doing a great job right now. I really would love more of these very informative articles that help you so at seeing the big picture.

    A really helpful article.

    I’m a bit disappointed by you inconsistency…

    The comparison with Intel over who wins….slightly inconsistent but no biggie.

    What really is bad though, is the penultimate page – is socket 939 worth it?

    I agree it is but…..
    You’ve taking an identical chip and found it about 5% quicker than on socket 754. OK, no problem. But AMD have wacked a whopping 12% increase in rating, to 3800+ from 3400+. It doesn’t gel, the numbers don’t work.

    The 3800+ is also more expensive than the 3400+ to the tune of about 250% here in Australia and about 220% over there in the U.S. a 5% increase in performance does not warrant a doubling in price.

    way to go Anand...excellently comprehensive article...

    /waiting for those HDD articles you promised : p

    Going along with what #6 said:
    Athlon 64 4000+ - 2.4GHz - 1MB - 128-bit
    Athlon 64 3800+ - 2.4GHz - 512KB - 128-bit
    Athlon 64 3400+ - 2.4GHz - 1MB - 64-bit <---should be a socket 754 3700+ right?
    Athlon 64 3400+ - 2.4GHz - 512KB - 64-bit
    Athlon 64 FX-53 - 2.4GHz - 1MB - 128-bit

    #12, even GPUs aren't going anywhere fast. There's still a shortage of something or other needed to make the Ultra/PE parts, and there isn't a planned refresh for 2004. ATI/Nvidia have another speed grade of RAM to jump to(1.6ghz GDDR3), and can die-shrink down to 90nm once TSMC gets there, but they're so close to CPUs right now, they're destined to hit the same wall too.

    Anand, someone has been a busy beaver.;-) That was a long, but well thought out and informative article; you've basically written the definitive CPU article for now until the multicores come out.

    Ah I read the conclusion wrong.
  • Tides - Tuesday, October 19, 2004 - link

    why is this site putting down an amd performance gain and making excuses for intel at the same time.
  • Doormat - Tuesday, October 19, 2004 - link

    Its a shame the processor wars are coming to an end. I see dual core as neat, but a dud performance wise. It'll be another year or two before the GPU wars start to die out... hmmm..

    -CPU performance levels off
    -HD capacity levels off

    The only interesting stuff going on is GPU stuff.

    Best artical from Anandtech I've read in a long time. Good job Anand.

    wait nevermind, you put your comments ABOVE the graphs. threw me off cause this isnt what you usualy do...
