Until I retest Unreal tournament on KV8 PRO we continue with some CPU benchmarks!
46. Super pi is a single thread application that care about IPC and clock frequency above all else! Let's see if dual channel makes a difference:
A. KU8
B. KV8 PRO
C. UL8
D. AV8

And it does! 10% just like the PR difference between the socket 939 Athlon 64 3500 and socket 754 Athlon 64 3200!! For the first time we get what AMD told everyone: dual channel leads to ~10% better performance!

47. CINEBENCH 2003 is an old version that is perfect for period correct single core systems and dual cores/hyper threaded ones. We are interested in the CPU score:
A. KU8
B. KV8 PRO
C. UL8
D. AV8

And just where you thought dual channel justifies the PR rating we got this! Absolutely no scaling at all! Cinebench cares about the frequency and only frequency!

48. Tom2D is the only GUI test in the entire suite; it is highly controversial with nforce2 wiping the floor with VIA on socket A and K8T800 wiping the floor with nforce3 on socket 754.
A. KU8
B. KV8 PRO
C. UL8
D. AV8

All 4 platforms have serious problems with GUI acceleration. And socket 939 perform worse than their socket 754 counterparts! Unless a miracle happens the PR of socket 939 Athlon's is vastly overestimated!
