Blackford/Greencreek (Xeon): 21.3GBs mem b/w per motherboard G35, DDR2 Mode (Core 2) : 12.8GBs mem b/w per motherboard G35, DDR3 Mode (Core 2) : 17.0GBs mem b/w per motherboard Socket F Opteron : 10.6GBs mem b/w per physical CPU Socket AM2 Athlon64 : 10.6GBs mem b/w per physical CPU Memory performance increases with CPUs in AMD platforms, decreases in Intel platforms. That's the incredibly naive version, anyway. -- ______________________________ / Jo Shields <[EMAIL PROTECTED]> \ | Systems Manager, | \ Oxford Supercomputing Centre / ------------------------------- \ ,__, \ (oo)___ (__) )\ ||--|| * -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
