AMD's Quad FX: Technically Quad Core

How does a 3GHz Athlon 64 X2 Perform?
Although today's story is mostly about AMD's Quad FX platform, there is a little gem worth mentioning. AMD's top of the line Athlon 64 FX-74 processors run at 3.0GHz, the highest shipping frequency of any AMD desktop CPU. While it won't be until next year before we see 3.0GHz in an Athlon 64 X2, we were curious to get a little preview of what the dual core race would look like early next year. Note that many of these tests are using updated benchmarks using newer versions of our applications and thus can't be compared to previous results.
The showdown is between the Athlon 64 X2 6000+ (3.0GHz, 1MB L2 per core) and the Intel Core 2 Extreme X6800 (2.93GHz, 4MB L2):
Intel still has the performance advantage, even once AMD reaches 3.0GHz. We didn't expect another 200MHz to do much but it's further confirmation that AMD will need a new architecture to compete; the second half of 2007 can't come quickly enough for AMD.

I image www.Scan.co.uk in the UK will stock both boards and cpus at realistic street pricing.
And I am seriously thinking of getting one, to put lots of PCIe cards into, and for use WITH A NUMA AWARE OPERATING SYSTEM.
Who knows, Asus may even release a bios upgrade for it!
And also note that there is a similar Asus "Deluxe" board not just the WS workstation variant, so may be a little cheaper.
My other options are a dual socket Opteron board (with expensive memory) or a Core2Quad, using Nvidia 680i chipset which gives less I/O capacity.

Or, you could go for a dual socket Xeon system. It would cost near the same, and you'd have the option of two quad-core processors RIGHT NOW. (Rather than late next year.)Of course, then you run into more expensive (and more power-hungry) memory. But if you are actually looking at such a system, a Xeon might be a better fit.

The funny thing beeing, the biggest value of QuadFX is in the exceptional motherboard. Except those those 10 not routed USB ports, that board is a dream come true.
And yes, those 12 SATA3G ports would be a blessing for my storage needs...

Nice costings, I'm thinking the same here.
That board has lots of I/O bandwidth.
Since the Gbit ether ports support teaming (2 muxed together), I would have thought it worthwhile for Asus to implement all four rather than two.
Four used separately would make nice routing between lans, and four used as two teamed pairs would give > 1Gbps performance in and out eg as a firewall, or as a server with redundant connection, or to talk to NAS boxes etc. Two extra nets wouldn't push the power consumption up by much.
Hopefully Asus (or other) will produce a rev2 board with the extra ethernets.

There's support for 14 USB ports AFAIK, 4 on the back, and 5 headers on the mobo, which makes 14 I think, which still isn't 20, but it's more than enough, and it's more than 10 :P

No, those 2 headers are for IEEE1394...SLIM - Thursday, November 30, 2006 - link
Is this just a prelim review only talking about the processors and the real review is still to come? I mean the only reason for this platform to exist is the 4 GPUs not the cpus. Let's see 4 8800gtx's with the FX74s playing at insane resolutions in games that intel simply can't fathom due to the lack of support for 4 gpus (at least as far as I know of).The 4 gpus are the point of this platform, not power consumption, not 3dsmax... GAMES WITH 4 GPUS! I don't mean to be too abrupt, but the boards got 4 graphics slots for a reason.

A single 8800gtx is already being bottlenecked by a core 2, let alone them in SLI.Quad SLI will not have any performance advantage over SLI, as the processing power to feed them is just not there.

I dread to think what the power consumption of a system with the FX-74s and four 8800GTX cards would be. It would probably be close to 1KW, possibly even around 1100W or so. That would be insane!JarredWalton - Thursday, November 30, 2006 - link
Given that this "4x4" initiative is apparently going to use NVIDIA graphics cards, and NVIDIA makes both AMD and Intel chipsets, if they decide to do anything with quad G80 chips you can pretty much guarantee that it will be for both platforms. Thus, 4x4 is really 2x2 right now, whereas the 775 platform is 1x4 and Xeon is 2x4. In the future, AMD will have 2x4, and perhaps all the platforms will support some silly quad GPU configuration.Basically, quad SLI was all about the pissing contest. "Oh yeah, well I have for GPUs and you only have two!" Then there was the completely bogus marketing material that they sent out with quad SLI talking about how great the extra GPUs would be for accelerating physics calculations. I suppose it's possible that in the future such applications will become useful, but almost a year after the initial talk of NVIDIA physics acceleration and we have yet to see any actual demonstration of this capability. Anyway, this Quad FX is just the same thing as Quad SLI: potentially good marketing, but lackluster final performance and terrible heat and power requirements.
