AMD QuadFX Platform and FX-70 Series Launched
MojoKid writes, "AMD officially launched their QuadFX platform and FX-70 series processors today, previously known as 4x4. FX-70 series processors will be sold in matched pairs at speeds of 2.6, 2.8, and 3GHz. These chips are currently supported by NVIDIA nForce 680a chipset-based, dual-socket motherboards, namely the Asus L1N64-SLI WS, which is currently the only model available. HotHardware took a fully configured AMD QuadFX system out for a spin and though performance was impressive, the fastest 3GHz quad-core FX-74 configuration couldn't catch Intel's Core 2 Extreme QX6700 quad-core chip in any of the benchmarks. The platform does show promise for the future, however, especially with AMD's Torenzza open socket initiative." And mikemuch writes that the QuadFX "not only fails to take the performance crown from Intel's quad-core Core 2 Extreme QX6700, but in the process burns almost twice as much electricity and runs significantly hotter in the process. ExtremeTech has a plethora of application and synthetic benchmarks on QuadFX, including gaming and media-encoding tests."
This is true, while Amd lags now, it is still on 90nm while intel is on 65, when both are on 65 then we'll have some real competition going on. -Ed
So you see what had happened was....
it's strange that the new amd processor is only supported by an nvidia chipset, now that amd owns ati
The Extreme Tech benchmarks seemed to expose a lack of windows XP's ability to benefit from NUMA. I wonder what testing on a newer linux kernel with NUMA scheduler support would show.
Ahh... Someone that gets this concept.
Intel wins on extra Cache- and the benchmarks that keep getting ran don't reveal performance snags with the SMP operation.
Intel's got a shared L2 that's 2-4 times the size of the AMD equivalents' pool.
AMD's got a coherent, but NON-shared L2 split across multiple CPUs- each core has it's own L2. You'll have less L2 thrash with that design.
Under an SMP load, the AMD design will have an edge if all four cores are busy in different parts of system memory.
If you pop out of cache, the memory bus design and overall architecture of the AMD parts will have an edge.
Intel has an edge only due to process shrink and the things they can do as a result thereof. As soon as AMD goes to the
smaller process size, they'll pick up the lower TDP advantage Intel has right at the moment and then the whole deal will
flip-flop on who's got the "best" CPU unless Intel comes up with a few new tricks along the way, which may/may not happen
for them.

Sooo... when Intel had the hotter, more energy wasting, slower processor... it was "omg look how much Intel sux0rz" but now when AMD is in that boat its... "this is just a stopgap, you just wait!"
Fanboys... it just doesn't get more entertaining then that.
Intel spent years in that boat with no indication that they had an intention to 1) aim for low power consumption (they were happily gloating about the forthcoming Pentium 4 5GHz) or 2) do what it took to gain the performance crown. It was not clear (in recent history) that they had an eye on the super-performance desktop market until the announcement of the Extreme Edition and little indication of concern about power usage on the desktop until they announced that their new desktop processors would be based on the Pentium M.
On the other hand, we already know AMD's plans for next year, and we have statements of what they hope to achieve. I'm not saying just to wait and that it will be awesome. I'm posting on a Core 2 Duo system built using the remnants of my last Athlon XP system. My previous post indicated my expectations for what AMD is doing from a business perspective, not my feelings about the company or their product.

You're right - crap is not good for consumers!
The cesspool just got a check and balance.

Anybody running a 2.4.2 version of the Linux kernel should be shot. Nobody runs 2.4.2 these days and anybody suggesting that is far out of touch with what Linux is doing. Compare it against 2.6.19 with all of the NUMA options turned on (CPU local memory allocators, RCUed algorithms) and you'll see an expected an expected trumping of XP for kernel load hands down because of all of the MP work on it over the 4 years.
