Gaming Performance was consistently faster on the new 90nm than the existing 130nm processors. This varied from 2% in Aquamark3 and Doom3 to 7% in Quake 3. Overall, gaming averaged about 3% faster on the new 90nm chips. While 3% is not a huge increase and it will likely not even be noticed by the average user, it was still impressive to see the new 90nm chips perform a little better than the older 130nm chips.

We have talked in past reviews about how some games respond well to CPU and memory speed increases, while others seem to be most influenced by the graphics card. This is nicely illustrated in comparing benchmarks of the 3000+ at stock speed to the same benches at 2.6GHz (290x9). Here, we see games like Return to Castle Wolfenstein, Unreal Tournament 2003, Quake 3, and Comanche 4 improve 34% to 42% as we move from 1.8Ghz to 2.6Ghz. At the other end of the spectrum, Halo and Aquamark 3 only improve 12% to 13% while the CPU speed increases 45%. Doom 3 falls in the middle with a 24% increase in frame rate for the 45% boost in CPU speed.

    nevermind...

    It is only for sale in 1 gig packs of 2x512 right now, different part #:

    Also.. is that ram available in the retail channel? I wanted to look up the price, and found the part number(I believe) OCZ400512ELPER2

    However, this isn't on newegg, or pricewatch.

    If you already have overclock results of a p4 from another article, how difficult would it be to include in the graphs? Or were those results using a different enough configuration that it is not an applicable comparison?(In which case, as a reader that loves Anandtech for your thoroughness, I would like to see an applicable comparison.)

    All in all, good review. Not as overly wordy as some have been recently(Though I won't name names. ;P).

    With the 3500+ showing a 20% overclock and the 3000+ hitting a 45% overclock, it would be great to know how the 3200+ would overclock in this comparison.

    Wesley, thank you so much. Once again, another fine job.

    Further to my earlier comment, the default core voltage of all the Winchester-core 90nm A64 parts currently available is 1.4V, not 1.5V as indicated in the review. Its important this is corrected on the Overclocking page of the review as it is very relevant to the obtained results.

    I now see that you didn't actually measure the temperature under full-load conditions. Other reports suggest that the 90nm parts do run cooler when idle than the equivalent 130nm parts, but are hotter under full-load conditions due to the higher thermal density. They have been measured as using less power under full-load than the 130nm parts, but run hotter because that power is concentrated in a smaller core.

    I'd be very interested to know just how hot that 3000+ got under full-load conditions (eg. running Prime95) when you were feeding it 1.6V instead of 1.4V, and had it clocked at the maximum of 2610MHz. If you were using the standard retail HSF, it may have been rather hot :)

    ----

    As for why the 90nm parts run a little faster than the 130nm parts, I found this post on the AMD forum. I don't know if the info is accurate, but it sounds reasonable:

    Whether the 90nm process for the 3000+ to 3500+ runs cooler is still up for speculation to a degree. What will eventually be shown is that the TDP for these processors is lower than the current 130nm. (currently it is 89W TDP, the TDP for these three - when the information is released - is 67W).

    In addition the 90nm A64 (DH8-D0) has these improvements over the 130nm (DH7-CG):
    - improved DRAM page closing policy
    - improved memory addressing with graphics cards using main memory (eg. integrated cards) as frame buffer
    - memory controller power reductions (DDR receivers go off in default)
    - memory power consumption reductions (CKE pins disconnect)
    - second write combining buffer
    - SAHF and LAHF instructions are now supported in 64bit mode

    #22 - I appreciate your suggestion, and we did overclock the Pentium 4 775 in our "Intel 925X Roundup: Creative Engineering 101" at http://www.anandtech.com/mb/showdoc.aspx?i=2162.

    The highest stable overclock we could achieve with the P4 on air cooling was 3.92GHz (280x14) on the best overclocking 925X board. Others have achieved higher overclocks with water and phase-change cooling, and higher overclocks will also likely be achieved with those methods on the new 90nm Athlon 64 processors.

    We will be looking at Pentium 4 overclocking again in the upcoming launch of some new and improved P4 processors.

    I am an AMD freak, and Im happy they launched the winchester. You should have, however overclocked the Pentium-4 also, just to compare the scalability of both the CPUs.I had read an article on somebody overclocking the pentium-4 to 6 Ghz. Though this was an unstable overclock, what this indirectly implies is that despite of have a 30-odd stage pipeline, intel may find it difficult to reach speeds in excess of 5Ghz using the 0.09u process...I expect a more thorough comparo soon.....
    cheers!

    All the buzz in this article is about the O/C'ing capabilities of the new .90 die...personally im just as impressed or maybe even more so with the performance of the memory used in this testing. Having made that statement it is clear that the O/C'ing capability of the 3000+ version of this Proc. takes us back to the good old days of the Celery 300.

    #11 & #16 - The memory brand is identified in the "Performace Test Configuration" on p.4 and the timings are in Overclocking table on p.5.

    The OCZ PC3200 Platinum Rev. 2 and other top performing memory is tested on the Athlon 64 in "Athlon 64 Memory: Rewriting the Rules" at http://www.anandtech.com/memory/showdoc.aspx?i=222... Some memory in that review made it to DDR618 on A64, but DDR580 at 1T was the fastest 1T performance.
