Doom 3
Our Doom 3 CPU Battlegrounds article already made it quite clear that Intel did not have what it takes to be the highest performer in Doom 3. The release of the Athlon 64 4000+ and FX-55 further extend AMD's lead in Doom 3.
Even the entry level Athlon 64 3200+ has no problems outperforming the 3.4EE
and Pentium 4 560. Doom 3 does continue to show us the ~7% performance improvement
we've been seeing thus far from going to a dual channel Socket-939 setup
over Socket-754. The added cache of the 4000+ manages to yield a 3% performance
improvement over the 3800+, definitely not worth the added premium over an
already expensive chip.
Prescott does well here (for Intel), but the Extreme Edition still takes the
cake.
Counterstrike: Source
The next big game after Doom 3 is, of course, Half Life 2. And while the game is still not out, Valve's Visual Stress Test that comes with Counterstrike: Source gives us a good glimpse into future performance under Half Life 2.
Just like Doom 3, Half Life 2 is strictly an AMD dominated game. The Athlon 64 FX-55 outperforms the fastest Intel CPU here by a whopping 18%. Prescott performs horribly, with the Pentium 4 560 only able to outperform the Athlon XP 3200+, not even the Athlon 64 3000+.
What is extremely interesting here is the impact of memory bandwidth on the Athlon 64 platform. The impact of a dual channel memory controller is nothing short of 14%, which is almost double of what we've seen in other tests. The Athlon 64 4000+ also shows a similarly impressive performance improvement due to its larger L2 cache, putting it a full 8% faster than the 3800+.
So far in gaming, AMD takes it 2 for 2.
Halo
The gaming performance dominance continues under Halo 1.05, with AMD taking the top three spots. We see much less of an impact from a larger L2 cache on the Athlon 64 platform than we did in the CS: Source VST, but dual channel is still worth close to 6% for the Athlon 64.
Prescott once again doesn't fare very well, with the 3.4EE leading the pack from Intel.
That's 3 for 3 for AMD.
Starwars Battlefront
We recently introduced Starwars Battlefront into our GPU tests last week with the release of NVIDIA's GeForce 6200. This week we're using the same test for AMD's CPU launch.
Overall we see that there's not much variance with CPU speed in Battlefront; obviously the XP 3200+'s performance is a bit dated, but the majority of the contenders here end up performing rather similarly to one another.
AMD does end up on top once again, which is not a surprise considering what we've seen in the past three tests. It would be very safe to say that AMD's Athlon 64 architecture with its on-die memory controller is very well suited for gaming performance.
Battlefield Vietnam
Battlefield Vietnam is similar to Starwars Battlefront not only in its gameplay but also in its performance; there's no real difference between any of the top performers here. Almost all l of these CPUs end up being GPU limited at 1024x768.
Unreal Tournament 2004
UT2004 sends AMD back to the top of the performance charts, with the top four spots once again belonging to AMD. We also find that the 4000+ improves performance by about 5% due to its larger cache, while the 3800+ continues to make a 6.7% argument in favor of Socket-939 over Socket-754.

It 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 - link
Val,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.
Learn to read forums and how to troubleshoot your PC.

what the hell did val just say?Philbill - Wednesday, October 20, 2004 - link
Sounds to me as though the Intel fanboys are worried :)val - Wednesday, October 20, 2004 - link
53: 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 - link
51: 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)

51: 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.

#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."
http://www6.tomshardware.com/cpu/00q4/001017/athlo...
"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.:)

also 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.
