The next days I'll get a performance time benchmark for a

2 x AMD Opteron 2427 @ 2.39 GHz
8GB DDR2-800 @ 433 MHz
Supermicro H8DAi+-F (Dual SR5690 Chipsets)
ATI (MSI) Radeon HD 5850 "OC" @ 900/1150
Windows Vista Business SP2 x64

So we'll get a fair estimate how the Opteron Istanbul 12 core will perform for a 100M number ... :tu:

Yeah, he has overclocked it to 2.4 Ghz ... but haven't heart from him about the end result.

He told something about only 45 % performance with 12 threads in one worker thread (so mprime might be running very bad for cores > 6 ).
