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.

southernpac - Wednesday, October 20, 2004 - linkIt has been reported elsewhere that the FX55 runs 15 degrees hotter than the 4000+, and that Cool & Quiet are available on both. True? Also, does the new AMD stock fan (with the copper fins and heat pipe) come with the 4000+?
ThePlagiarmaster - Wednesday, October 20, 2004 - linkVal,
Sounds like you don't know how to build a PC properly. With a good PSU and QUALITY memory (corsair, kingston, crucial etc) you won't experience any problems with AMD systems (with any motherboard). If you still experience problems turn off that damned SPD. Config the memory yourself and problems go away. I don't even use SPD's when setting up customers PC's these days. If there is a way to turn it off and config the memory myself it's the first thing I do.
All SPD's are not created equal (nor are PSU's). Tons of them out there will make your machine run like crap. A simple fix is to kill it and config the memory yourself in the bios.

nastyemu25 - Wednesday, October 20, 2004 - linkwhat the hell did val just say?
Philbill - Wednesday, October 20, 2004 - linkSounds to me as though the Intel fanboys are worried :)
val - Wednesday, October 20, 2004 - link53: yes and Acer on all their notebooks and servers :-). And Britney never touched Sprite. Please try to discover what PR means. Google will help ya.
val - Wednesday, October 20, 2004 - link51: to your 820 and other sarcastic notes, everybody makes mistakes, but with intel you have allways choice. If you dont like to buy intel chipset with limited warranty with purpose to be used on cheapest office PCs, you can buy workstation or server based chipset . But what you can choose for AMD? Is there any high durable VIA chipset? Or nvidia, SIS? Dont make me smile.
(note: i have 820 in my HTPC and since installed it runs fine)
Sunbird - Wednesday, October 20, 2004 - linkFerrari uses AMD..... Word!
val - Wednesday, October 20, 2004 - link51: that AMD madness will end one time, and AMD chips (and specialy chipsets for AMD) have not one bug - there is one difference: intel is serious respected company, which doesnt depend on how few overclockers will like or dislike them. They must publish the bugs for this reason. AMD is not publishing any, even that stupid one with JPEG was hidden under carpet as much as was possible. And should we discuss chipsets for AMD now? Like VIA deleting harddrive with ATI card, and many others?
Reason why many of them are not scared to install AMD servers is, that demand is not so high. If you have single purpose server with backup, you can run it even on ATA drives and ALI chipset to reach 99.3%.
Name me one company which prefers AMD and doesnt produce intel, name me one industrial computer who support AMDs, one automotive rack test system provider, hospital equipment, avionic systems, and so on. Its not like that few overclockers will not see their page for a ten minutes, its about lifes and lot lot of moneys. And trust me, its not about marketing or idiocy, its about quality and support what you will never get from AMD/taiwan.
Get Intel, and dont fall to temporaly madness.
I know that Hyundai is popular now, but it is not BMW (even when you can get three hyundais for one BMW and even when one is able to drive on straight road same top speed). Respected companies doesnt change so fast.
About benchmarks? I like to see once, where is compared how many interupts and system calls is CPU able to handle. Benchmark with network and soundcard, mouse, keyboard and other utilization. You will be surprised.
Zebo - Wednesday, October 20, 2004 - link#49 like to spread FUD much? Total BS. That's why Anands, you know the guy who reviews hardware professionally seeing thousands of products a year, been using AMD servers for four years now, right because thier unreliable?? IMO ihere is actually no more effective endorsement of the stability and reliability of AMD platforms than the fact that AnandTech uses them as the sole platform for the web serving of its main site.
Need we bring up intels i820, grantsdale, alterwood disasters? Even the prescott has 31 bugs which will blue screen your comp under certain sofware instances. Thus far opteron/A64 has one. Hav'nt you heard about intel recalling processors? Hav'nt you heard about Northwood sudden death syndrome? Hav'nt you heard about HP Recall Thousands of pentium Notebooks for chipset problems?
If there's any instability to be had it's with Intel simply because AMD "offloads" about 80% of a chipsets work to the CPU's interated mem controller now.
Those "AMD bad chipset" museings were all FUD way back when too. No need to rehash them, I will if you want. But Just look what Intel man, TOM's hardware says way back then. http://www.tomshardware.com/mainboard/01q1/010122/...
"The most important finding was the enjoyable fact that each of the tested boards ran 100% stable even at the fastest possible memory timing settings. VIA's upcoming DDR chipsets may not look too impressive right now, but the Apollo KT133A is a matured, fast and solid product that offers good performance."
"AMD Processors are significantly less expensive than Intel processors although they are at least on par in terms of performance. - FACT"
"AMD processors are incompatible. - LIE
Not that the average guy who just heard that phrase would know what the heck 'incompatible' is, but it sounds really bad, doesn't it? Well, even the people who do know that 'incompatible' means that a product wouldn't work reliably with other components (which of course is bad) are wrong if they accuse AMD's Athlon or Duron processors of it. In our labs we are testing all kinds of Athlon platforms with all kinds of different components and I can definitely say that I cannot see any difference between the compatibility of AMD products and platforms compared to the same from Intel."
"Chipsets for AMD processors are inferior to Intel chipsets. - LIE
Yeah, sure, the earth is flat and politicians are honest ... I am still amused when I see people posting the above message in news groups or as their response to articles. How many more times does Intel need to screw up their chipsets (i820, MTH, ...) until you guys get the message? . . . Incompatibilities are more a problem of the motherboard BIOS than of the chipset right now. Thus both chipset makers, Intel as well as VIA, are actually in the same situation."
Stop the hate budda. Get AMD, everyones doing it.:)
val - Wednesday, October 20, 2004 - linkalso should the countries to do something with AMD/Intel NVIDIA/ATI cartels. CPU / GC costs so much more than whole mainboard. Thats crazy. More competitors to the battlefield or some kind of regulation is needed.
