Re: AMD's dual core Opteron & Athlon 64 X2 Launch - Server/Desktop Performance Previe

Check out Anandtech's Multitasking Benchmarks starting here. IMO outside of Single threaded app/games - Athlon x2 benchmarks are compelling. You could also consider these cheap Duallies that will in most cases outperform a equivalent Single core Dual Opteron setup.

x2-4200 (2.2ghz 512K Dual Core (Dual 3500+)) ~$537
x2-4400 (2.2ghz 1024K Dual Core (Dual 3700+)) ~$581
x2-4600 (2.4ghz 512K Dual Core (Dual 3800+)) ~$803
x2-4800 (2.4ghz 1024K Dual Core (Dual 4000+)) ~$1001

Opteron 248 (2.2ghz 1024K) $450 x 2 = $900
Opteron 250 (2.4ghz 1024K) $670 x 2 = $1340
