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

Motherboard Support Powered by NVIDIA & VIA
Unlike the release of the original Athlon, AMD has full industry support behind the Athlon 64 (although the same can't be said for industry confidence). We have seen chipsets from ALi, NVIDIA, SiS and VIA, however only NVIDIA and VIA are dominating AMD's launch.
Our own Wesley Fink has prepared an article comparing the NVIDIA and VIA solutions, so be sure to check that out if you're interested in the detailed differences between the implementations of the two chipsets.
Because AMD has integrated the memory controller on the Athlon 64's die, the amount of work that needs to be done by the chipset vendors has been reduced significantly. The performance difference you'll see between chipsets should be negligible (even more so than in conventional architectures) as the only variables between chipsets are the South Bridge (IDE, PCI, SATA controllers) and the AGP controller.
AMD has no favorites in the chipset game; although they shipped all initial review systems with nForce3 boards, their reasoning was primarily one of availability, as they had to ship systems out in the summer to meet the deadlines faced by print publications.
As you will find out in Wesley's review, the nForce3 is currently limited to a 600MHz Hyper Transport link between the CPU and the chipset, while VIA's solution runs at 800MHz. The performance difference due to VIA's bandwidth lead is negligible however; remember, we're not talking about memory bandwidth, rather bandwidth between the CPU and the AGP controller. NVIDIA will have 800MHz support in the next version of the nForce3, the 250.
Despite the fact that chipset costs have gone down (as there's no more memory controller), motherboards will not reflect the lower price initially according to motherboard manufacturers. AMD is positioning the Athlon 64 as a premium part and thus the motherboard manufacturers will position their solutions competitively, but don't expect to see lower-than-Socket-A prices.
What's also interesting is the incredible recognition that NVIDIA has managed to establish in the chipset industry with the nForce brand. We are seeing incredible support for nForce3, despite the fact that it doesn't really offer anything above and beyond VIA's solution. We're expecting the nForce3 to be positioned as a premium solution, while VIA will compete for the lower end of the Athlon 64 market - all because of the success of NVIDIA's nForce2 brand; the name nForce3 somehow just sounds all that much more powerful, even though NVIDIA's powerful memory controller isn't being used.
At the start, it looks like NVIDIA will begin to pull ahead as the market leader, but it is unclear how VIA's support for an 800MHz HT bus and potentially lower price point will change things (if at all).

Anyone know how the new AMD CPU compares to the Apple G5? I am not an Mac-Apple guy, but my in-laws are, and I'd like to be in the know in case we get into a friendly "discussion" about the Windows and Mac platforms.Anonymous User - Tuesday, September 23, 2003 - link

This review appears to be in the same general lines as the rest of the Opteron/Pentium comparisons; I'm pleased that AMD has managed to shore up their shortcomings, but the price point is what's keeping me away from going directly from a pre-XP AMD Athlon to Athlon64. If I spend $400+ on a processor, it better be the king of the hill for the next year at least, or at least the mobo should be upgradeable to compensate for CPU obsolesence.And I'm surprised no one's figured out how to unlock Opteron multipliers yet, since that's basically the heart of the early-day AXP overclocking scene... Bridge blowing, soldering, "wire mods", etc. Shame, shame on you overclocking enthusiasts for not throwing everything into unlocking the hottest new processor (figuratively, not literally; Prescott and P4EE take that award at 103W and 150W, respectively). :P Talk about good wholesome fun, take an Opteron at 3.4GHz (using multipliers) and slap that Zalman Cu-7000 thing on it; a Pen-what?
#58: No, there are dumber fanboys than Intel fanboys, trust me. Just visit Something Awful. :/

Is AMD actually planning on selling these versions of the 64? They and the hardware will be obsolete the day they are purchased. THe two biggest advantages the chip has can't even be used yet. The new mobos can't handle any more Ram than the current Pentium boards, I thought being able to use more ram was one of the selling points of the 64? Although that point seems to be moot anyway until a new 64 bit os is out.Anonymous User - Tuesday, September 23, 2003 - link
#36 You're right dude. Intel indeed said that prescott 3.2 GHz can't touch the performance of the 3.2 GHz P4EE. Logical actually, since prescott has no extra L3 cache, and a longer pipeline. The only benefits are: larger L1 cache, larger L2 cache and SSE-3 (only needed for sysmark-2004 LOL!, and other intel benchmarketing partners)Anonymous User - Tuesday, September 23, 2003 - link

original pentium 66 was pants got beat by a 486original pentium 4 was just as bad
give it 6 months for the chip to mature. hopefully the athlon64 is a success cause if amd go bust we all pay double for cpus

There's some confusion on using the term 32bit and x86 here. I believe what was mean in response to what #32 said, is that A64 runs x86 natively the same way a XP does with no emulation, (as was outlined in previous Anandtech articles) just by disabling half of the 64-bit registers. So it had better run at least as well as the Athlon XP/P4 or there is something seriously wrong... not something to brag about.#50, For an Intel fanboy you sure don't know your history. Using 386 would be more appropriate as that was the change from 16-bit to 32-bit... and things have not fundamentally changed in the instruction set since then.
