.09 Athlon 64: Value, Speed and Overclocking

General Performance
Because of the real world performance measured by the Winstone benchmarks, we did not really expect any difference between 90nm and 130nm results. However, the 90nm processors perform a bit faster than 130nm at the same speed in Business Winstone and Mutlimedia Content Creation Winstone. The differences are very small, but this is the beginning of even larger performance differences in Gaming benchmarks.
It is interesting that a 45% increase in clock speed (1.8GHz to 2.6GHz) on the 3000+ yields a 33% increase in Content Creation scores, but just 24% in Business Winstone. This is just another example showing that multimedia is much more impacted by CPU speed than standard Business applications.

Great article.Great CPU, now all we need is PCI-E bords.

I haven't finished reading the article, but in the overclocking section of the review, you say the 3500+ overclocked from 2200 to 2610MHz at the default core voltage of 1.5V, and that the 3000+ went from 1800 to 2610MHz just by raising the core voltage from the default of 1.5V up to 1.6V.I was under the impression that the default core voltage for the 90nm parts is 1.4V! Was the mobo BIOS version used not correctly setting 1.4V by default, or is the default actually 1.5V?
If as I believe the default is 1.4V, both chips were overvolted to reach 2610MHz, and the 3000+ in particular had to be raised from 1.4V to a much higher 1.6V. Its good that it still seemed to be running at a normal temperature!

wesley, One more thing -- as a future idea for an article -- a comparison of typical systems running different memory speeds -- I was under the impression that the price / performance ratio is very poor ... eg. ddr600 is 80% more expensive but only gives 10% more performance?KHysiek - Thursday, October 14, 2004 - link
So this memory (double 512MB pack) was running at 580MHz ?! Wow.What timings then ?

thanks wesleyalso found this article for those who want to know -- no athlon xp's though , but you can guess -- I look at the ut03 botmatch table, they seem to be comparable over these three articles (correct me if im wrong)
http://www.anandtech.com/cpuchipsets/showdoc.aspx?...
For those who cant be bothered here's an interesting stat
prescott 2.8 - ut03 botmatch 67.9 fps
3500+/3000+ OC @290x9 132.7 fps
for those who are mathmatically challenged -- THATS DOUBLE!!! time to upgrade

I dislike overclcoking reviews that don't show a pentium equivalent in thier test.What I want to know if I buy a 3.2C or E for the same price and overclock it with similar cooling how it would compare too....does'nt everybody?
Reviewers really need to work these ideas in.

#11 - Mem:FSB was 1:1 in overclocking. At 290 we were still running 1:1.Wesley Fink - Thursday, October 14, 2004 - link
#3 and #9 -Results for the FX53 and Intel 92X/915 running the nVidia 6800 Ultra are available at http://www.anandtech.com/mb/showdoc.aspx?i=2128.
To help in comparisons we have added test results for the fastest current CPUs from AMD and Intel. The FX53 runs at 2.4GHz with 1MB of cache compared to the 512k on the 3000+ and 3500+. The Intel 560 runs at 3.6GHz and was tested on an Intel 925X chipset motherboard.

What was mem:fsb ratio in this overclocking (benchmarks) ?Wesley Fink - Thursday, October 14, 2004 - link
#1 - Table has been corrected.#4 - Corrections made. It should also be pointed out that Socket 939 nForce3 uses the Ultra chipset which already supports 1000 HT. It is the Socket 754 nF3-250 that normally supports just 800HT. All VIA 939 chipsets also support 1000 HT.
