AMD shows off enthusiast platform performing "mega-tasking"
AMD has been all over the news in the past week, first with its
massive price cuts
and second with its
merger with ATI
. In a bid to steal
Intel’s quad-core limelight
, AMD held a demonstration of its
previously announced 4x4 enthusiast platform
. The demo placed great emphasis on "mega-tasking," showing the 4x4 system running various multitasking scenarios. Some scenarios included playing games while a video was being encoded in the background or multiple CPU bound applications running simultaneously. AMD’s demo systems were powered by two unnamed dual-core Athlon 64 FX processors and compared to an Athlon 64 FX-62 equipped system.
During the event, AMD stated end-users should be able to pickup a pair of 4x4 compatible processors for under $1000. Previously, AMD had claimed that the 4x4 platform would be limited to the FX series processors only, and currently all FX series CPUs are priced at least $500. No specifications were available on bundled 4x4 Athlon 64 FX processors.
AMD 4x4 systems will be NUMA compatible allowing each processor access to its own pair of 240-pin DDR2 memory slots. However, memory capacity appears to be handicapped on 4x4 systems with a maximum of 2GB per processor. There was no mention of Athlon 64 X2 compatibility in 4x4 systems or details on the motherboards.

More Interesting on Vista

Since Vista is, as can be seen in the beta, going to hog all system resources for itself to schedule, I am interested in how the Dual Core Dual CPU Platform will work out on Vista, be it here or on Opteron. I'd think AMD would actually impliment a unified thread scheduler across processors in order to maximize single process performance while taking full advantage of the hardware in multithreaded environmnets (on Athlon X2/4x4, not Opteron please). Perhaps the L3 UniCache will do so per processor anyway. Most interesting will be rendering on Vista with Dual GPUs (perhaps just Crossfire by then!? ATi+ AMD). To see how Vista distributes the workload, and if the Drivers can direct it in the right way. Sofar, the OS is interesting and disturbing all at once.
