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."
The QX6700 has the same TDP(125-130W) per socket as the FX70-74 so I assume they run at about the same temperature on chip. Overall system temperature might be higher for the FX based quad core system since it uses twice as many sockets, but that's a matter of case design, if the case design can eliminate the heat from the heatsink effectively I would imagine both systems would run at the same temperature. This is of course ignoring the fact that AMD TDP is worst case and Intel's is average case.
