AMD Athlon 64 & Athlon 64 FX - It's Judgment Day

Intel's Preemptive Strike - Pentium 4 Extreme Edition
As we announced at last week's Intel Developer Forum, Intel preempted AMD's 64 launch with a release of their own - the Pentium 4 Extreme Edition.
The Extreme Edition is a 169 million transistor Pentium 4, currently running at 3.20GHz (800MHz FSB) with Hyper-Threading support, and featuring a 2MB on-die L3 cache in addition to the standard 512KB on-die L2 cache.
The point of adding such a large L3 cache is to basically give the Pentium 4 as many of the benefits of an on-die memory controller, without actually integrating one. Intel is weary of the on-die memory controller approach, simply because of the horrible experience they had with attempting to push the market in the direction of RDRAM 4 years ago; thus a large L3 cache is the next best option.
A large L3 cache helps to hide the overall memory latency by keeping more frequently used data in the L3 cache, and Intel chose the size of the cache very wisely. For example, a single frame of DVD quality video can't fit into a 1MB cache but a 2MB cache is more than enough to store it. The vertex buffer data in most modern day games also happens to fit quite nicely in the 2MB that Intel chose for the Extreme Edition (EE).
Intel is toying with the idea of releasing an Extreme Edition version of every high-end Pentium 4 (e.g. Prescott 3.40GHz Extreme Edition), however nothing is set in stone yet. We have already passed along the information that an Extreme Edition processor would truly be worthy of the name if Intel would unlock the processors, allowing overclockers to freely push their processors. In order to combat remarking, we also passed along the suggestion that only lower multipliers be made available.
Both of these suggestions were provided by AnandTech readers and were very well received by Intel, it may take some time but we may be able to get the chip-giant to budge on this one.
The Pentium 4 3.2 EE will be available in the next month or two and will sell for around $740 in 1,000 unit quantities. The processor will work in all current motherboards, most of which will not require a BIOS update.
The Test
We used nForce3 boards from ASUS (Socket-940) and Shuttle (Socket-754) to keep our Athlon 64 vs. Athlon 64 FX numbers as comparable as possible. All systems were configured with 512MB of DDR400 SDRAM and used ATI Radeon 9800 Pro 256MB cards with the latest Catalyst 3.7 drivers.

#38, Huh how heck are we forgetting something NO ONE KNOWS? Has Intel ever really givin an absolute upper limit to the Prescott clocks throughout the year? Last time I heard Tejas would takeover after 4.2Ghz.Anonymous User - Tuesday, September 23, 2003 - link
LOL, you all who think that intel is the winner here, just continue to believe so, but don't tell anyone.If Prescott was so great we should have seen "leaked" benchmarks by now. I saw benchmarks of the Clawhammer more than a year ago.
AMD can not outperform intel because they'll get problems with their supply. That's one of the main reasons AMD don't want to release a cpu that will beat all intel offerings. Imagine what will happen if everyone wants an AMD.

#35, Dude just frigging be quiet as I seriously hope you aren't saying crap like that in public.Anonymous User - Tuesday, September 23, 2003 - link
You guys are forgetting Prescott is capable of 4.6 GHz, and it'll have the price advantage.Anonymous User - Tuesday, September 23, 2003 - link
So what's the difference between 32bit with 64bit extensions, and 64bit with 32bit compatible mode.Anonymous User - Tuesday, September 23, 2003 - link
#29, Didn't Intel reps at IDF make comments to the tune of a 3.2Ghz P4EE offering up better overall performance than a 3.2Ghz Prescott? How heck is Prescott going to change things when it's debutting at 3.4Ghz and going to be up against an FX51 and A64 3400+ (possibly even FX55)?!!?? What part of that shows Intel sailing through 2004 when Prescott is expected to max out at around 4Ghz and A64 hasn't even gone through a die shrink and is already performance competitive with it from the initial 130nm A64 releases??!?Anonymous User - Tuesday, September 23, 2003 - link
Athlon64 isnt running in 32bit compatibility mode. It's still a 32-bit processor with 64-bit extensions, not the other way around. Pure 64-bit processors will trounce it in 64-bit apps.Just keeping up with Intel isn't enough, they needed to take the performance crown without any doubt to really gain back marketshare, right now this is just good enough to tread water, especially considering their pricing. How the next year plays out will be interesting though.

#32Wait till next year when the bugs of 64-bit drivers/software come onto your system. It will be Windows 95 all over again. AMD64 is an expensive disappointment.

For everyone saying that the Athlon64 was NOT the so-called AMD Killer, I just have one question:How can you say a 64-bit processor running in 32-bit compatibility mode that keeps up with the best Intel processor, the P4EE, disappointing? Me, I'm waiting for some more 64-bit programs to judge the strength of the Athlon 64. The fact that the Athlon 64 can keep up and sometime pass Intel in 32 bits is awesome.
BTW, I'm not an AMD fanboy. I have both AMD and Intel processors. But I find the Intel zealots are trying to discredit this processor by insisting on only looking at half the picture. Just my opinion.
