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.

In the end, benchies will tell all, but most insiders agree AMD will own the 4x4 space.
"most insiders agree"??? which ones???
Intel is compensating for lack of on-chip controller by using a more sophisticated pre-fetching mechanism, as well as other enhancements in fetching things before being needed. It is enabling them to spank AMD's *ss quite soundly with even low-clocked chips like the 6300. It remains to be seen whether shmushing two Intel chips together will saturate their new memory bus (also taking account of the higher caches on the Intel chips), or if AMD will pull ahead. I don't think it is possible to even make an educated guess yet! Perhaps the best way to compare would be looking at a head-to-head of some current Athlon 2 x X2 systems against Woodcrest 2x systems, since those configurations will be extremely similar to the eventual Conroe-based 4 core solution of Intel.

DOH! Of course that should have read "Opteron" not "Athlon".
Why do the Anandtech writers get to update their articles, but we don't get to update our replies??? ;)
