PC Watch has the scoop on AMD’s upcoming 4x4 enthusiasts platform. The article claims AMD dubbed its 4x4 platform Quad FX. The upcoming Quad FX platform is based around NVIDIA’s unannounced nForce 680a chipset with SLI compatibility. DailyTech previously revealed images of ASUS’ nForce 680a offering—L1N64-SLI WS. Initial Quad FX systems will be powered by AMD dual-core processors, though the platform should be compatible with AMD’s upcoming Stars processors.

AMD is expected to launch Quad FX with three processors initially—the FX-74, FX-72 and FX-70. AMD is shipping the FX-74, FX-72 and FX-70 in pairs at $999, $799 and $599 respectively. This undercuts Intel’s recently released quad-core Kentsfield Core 2 Extreme QX6700 processor priced at $999.

The processors will utilize AMD’s socket F and feature a 125 watt TDP and manufactured using a 90nm SOI process. Unlike AMD’s workstation Opteron 2200 series processors, AMD Quad FX systems will not require registered DIMMs and function with regular unbuffered DDR2.

PC Watch has also posted benchmarks of the upcoming Quad FX platform as well. The early numbers do not favor too well against Intel’s Core 2 Extreme QX6700 though.

At the really high resolutions, both systems are GPU bound. Therefore the small differences there are just your typical platform differences. It could also be that video drivers themselves may execute slightly better on AMD, so once things get GPU bound a little more efficiency in the driver makes the difference. Either way, comparing two systems at GPU bound resolutions and then making assumptions about the CPU's is not a good idea.

Second, you can't just say that the rumor is that the QuadFX mainboard will cost about $300, and then find one of the most expensive Intel SLI boards at $250 and declare the platforms equally priced. Even assuming the $300 price point for a QuadFX board is valid (something tells me the launch price will be over $300), there are plenty of good SLI boards for Intel down to $100. Those $100 boards have 95%+ of the performance and features of the $250 boards. On the other hand, by it's nature, there will be no 'value' boards for QuadFX. So compare $100 to $300.

Finally, regarding the power requirements, you can't just ignore the differences in pricing out a system. It looks like you'll need a 600 Watt power supply MINIMUM for AMD QuadFX, and the board shots I've seen so far show 24-pin + 8-pin power plugs which means a server-class power supply. The intel system needs good power too, but nothing exotic. All else being equal then, the power supply for the AMD system will cost about double what the Intel one does.

So, you can spend at least $350 more on the AMD QuadFX-74 system and get a bit less perfomance than the Intel QX6800 system would, or you can go cheap with the FX-70 processors and spend just the same as you would on the Intel QX6800, and get a lot less performance.

This is a bad deal!!!

QX6700 requires a motherboard and power supply conforming to EPS standards, which includes the 8-pin aux. connector for CPU power.

What's hilarious about his comment and most of the other 4x4 fans is that they keep mentioning the quad core as a replacement. It seems that AMD will be distributing these for free once they come out :)

If you want to take them into your account in your (... let's be kind ...) FLAWED comparision you have to include their cost (... let's be kind once again ...) which most probably will be in the range of $1000. Let's compare present with present ... and then compare future with future.

What happens couple of months or a year down the road ... when one of the CPU's fails (cause they are electronics after all) and maybe AMD thinks your model was too old and was already EOL'ed. AM2, AM2+, AM3, Socket F ... almost ran out of breath there. I wouldn't bet that Quad cores would be an easy direct replacement. And let's assume they will be! There is still the added cost to replace 2 cpu's.

Oh, lets also not forget that so far the QuadFX mainboards that have been spied are all E-ATX boards. So you can't put one in a regular size ATX case. While I will grant that there are some reasonably priced cases that will fit an E-ATX board, on a whole such cases are more expensive and there are fewer available.

None of this actually matters to me though, it's just amusing to watch the fanboys try to explain how QuadFX has some sort of advantage over QX6700. My 2 Athlon64 and 1 AthlonXP systems are serving me just fine, and if I were in an upgradin' mood, I certainly wouldn't spend any more than $200 on a CPU & mainboard.

BTW I see I got modded down above... did I say something factually wrong? Or was I just politically incorrect?
