AMD Athlon 64 4000+ & FX-55: A Thorough Investigationby Anand Lal Shimpi on October 19, 2004 1:04 AM EST

MusicMatch Jukebox 7.10
An audio encoding favorite of Intel's from past Pentium 4 launches, MusicMatch Jukebox shows the Pentium 4 3.4EE taking a small 3.5% lead over the FX-55. Despite Intel's first place victory here, AMD takes the next four spots. Once again we see that there's no performance difference between the 3800+ and the 4000+, but looking at the lack of performance improvement from the 3400+ to 3800+ jump we see why: MP3 encoding is quite CPU bound, larger caches and more memory bandwidth don't matter much, it's all about clock speed here. Thus it's not too surprising to see the Athlon XP 3200+ outperform the Athlon 64 3200+ thanks to a shorter pipeline and higher clock speed. AMD's on-die memory controller does little for it here, neither does Intel's Prescott core though.
DiVX 5.2.1 with AutoGK
Armed with the latest version of DiVX (5.2.1) and the AutoGK front end for Gordian Knot, we took all of the processors to task at encoding a chapter out of Pirates of the Caribbean. We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio.
Despite AMD becoming more competitive in DiVX encoding performance, Intel once again pulls head, with the Pentium 4 560 pulling away as the fastest DiVX encoder out of the bunch. Even the more reasonably priced Pentium 4 550 is able to outperfom the Athlon 64 FX-55, and it's not until we drop down to the 3GHz mark that AMD is able to win any ground.
Heavy optimizations for NetBurst give Intel the DiVX encoding performance crown.
XViD with AutoGK
Another very popular codec is the XViD codec, and thus we measured encoding performance using it instead of DiVX for this next test. The rest of the variables remained the same as the DiVX test.
Using XViD the performance situation is flipped on us, this time instead of Intel being on top we're left with the Athlon 64 FX-55 - although it's worth mentioning that the Pentium 4 560 is close behind. To no surprise there's a noticeable increase in performance from the single channel 3400+ to the dual channel Socket-939 3800+ of 7% to be exact. Once again we see no performance boost for the additional cache of the Athlon 64 4000+.
Windows Media Encoder 9
To finish up our look at Video Encoding performance we've got two tests both involving Windows Media Encoder 9. The first test is WorldBench 5's WMV9 encoding test.
Here we see that the Athlon 64 FX-55 and Pentium 4 3.4EE are basically tied for the first place position, followed by the Pentium 4 560 and all of the 2.4GHz Athlon 64s. Here the Athlon 64 3400+ appears to do about as well as the Pentium 4 550, which is either saying a lot for the Pentium 4 550 or very little for the 3400+.
But once we crank up the requirements a bit and start doing some HD quality
encoding under WMV9 the situation changes dramatically.
Here the Pentium 4 560 takes the lead, followed by the Pentium 4 3.4EE and then the FX-55. The performance difference between the Pentium 4 560 and the FX-55 is just under 9%, enough to give Intel the clear win here. Only the Pentium 4 530 is really able to be challenged by the AMD chips.
Closing up our video encoding tests, while AMD does win some, with appropriate optimizations in place Intel seems to be the right candidate here.

val - Wednesday, October 20, 2004 - linkfor me is AMD unacceptable until there are good chipsets. All i have ever seen or had in my computers was big garbage with permanent problems and mysterious difficulties.
Even SIS chipsets looks much better for intel than SIS for AMD. Its not anymore about CPU, CPU are fast for many tasks and that few percent of price or performance makes no deal, but overall quality talks strongly for Intel.
Save your time AMD fanboys to reply me something like that your AMD platform runs perfect and you had problems with intel and so on, its cheap and cannot anyway motivate me for change.
And yes, i have 2 AMD and 2 Intel computers and many i had or seen before (at home, work, school, projects, customers).
Gnoad - Wednesday, October 20, 2004 - link3GHZ! Wow, I already was an AMD fan, but that just totally blows me away. Crazy stuff.
GoHAnSoN - Tuesday, October 19, 2004 - linknice article. Thx
coldpower27 - Tuesday, October 19, 2004 - linkVery nice, I await the day AMD releases a 3GHZ Athlon 64. These processor are niced but priced in a range where volumes are rather low, they have nice bragging rights though :P
Da DvD - Tuesday, October 19, 2004 - link3GHz on air :S
AMD's really out of trouble for the coming year(s)
I can imagine K8@90nm scaling well beyond 3GHz...
(lol, or even top Prescott clockspeeds? That would be insane..)

Once AMD informed us that strained silicon was used in the FX55 I couldn't resist a bit of a run with overclocking the FX55. The nForce4 Reference boad is not really intended or designed for overclocking, since it doesn't have any CPU or memory voltage adjustments. However it does support a wide range of multipliers so I could try a few settinngs.
I had no probelm at all running at 14.5X or 2.9GHz at default voltage. At that speed I ran quite a few benchmarks and a Quake 3 of 604.2 FPS. The FX55 actually booted at 3.0GHz but it never made it through a stable XP boot. I suspect with just a bit of CPU voltage 3.0GHz would be possible with the FX55 on air. All cooling was just the new AMD stock fan which now includes copper fins and heat pipes.
verybusy - Tuesday, October 19, 2004 - linkThere is some FX55 and 4000+ overclocking info at http://www.hothardware.com/viewarticle.cfm?page=2&...
Assuming that my request from above is granted regarding other overclocking of 3500+, 3200+ and 3000+, I'd like to see just how overclocking turns out with the retail heatsink and fan. I hope that's not too much of a request.
verybusy - Tuesday, October 19, 2004 - linkI liked the review of the Athlon 64 4000+ and FX-55 and it was nice to see it compared to the other Athlon 64 3200+ and 3000+ processors running at stock speeds.
Unfortulately, with this review following so closely behind the 3500+ and 3000+ review (.09 Athlon 64: Value, Speed and Overclocking), it would have been very useful to see the 3500+, 3200+ and 3000+ overclocked to 2.6GHz as well. Afterall, the .09 3500+/3000+ @290x9 is faster than the FX53 (2.4GHz-1MB) err I mean Athlon 64 4000+). The overclocked 3500+, 3200+ and 3000+ could be pretty much as quick as the FX55 couldn't it?
That's what I want to see anyway.
ViRGE - Tuesday, October 19, 2004 - link#39, Anand mentions that it's multiplier locked.
Zebo - Tuesday, October 19, 2004 - linkGuys the 3400 newcastle is a way underated chip. It should have been, by all rights, called a 3600. I guess they did'nt want the 3500 to look bad agains a "old" 754 newcastle though.
As for the review, total AMD performance domination at low relative speeds temps and power consumption.:) Youd have to be a fool to buy intels netburst crap right now.
