[Rumor] First performance figures Interlagos?

[Musho]

Is this perhaps the first real Interlagos benchmark? From this post and on there are all the details!

F@H Benchmarks Interlagos (Without(!) Turbo core 2.0):
ubuntu 10.10 server x64
512G DDR3-1333
P6901
Average time/frame: 00:03:52

[09:15:07] Completed 0 out of 250000 steps (0%)
[09:18:59] Completed 2500 out of 250000 steps (1%)
[09:22:42] Completed 5000 out of 250000 steps (2%)
[09:26:16] Completed 7500 out of 250000 steps (3%)
[09:30:08] Completed 10000 out of 250000 steps (4%)
[09:34:06] Completed 12500 out of 250000 steps (5%)


For comparison:
Bulldozer "Interlagos" 16x4@ 1.8GHz* = 00:03:52
Opteron "Magny Cours" 12x4@ 2.2GHz = 00:06:40
*Look at the thread

Per thread, Bulldozer seems to be 58% faster than a K10 core at equal clock speeds in this F@H benchmark. JF-AMD already mentioned scaling wouldn't be linear with a whole module loaded vs just 1 out of 2 cores in a module loaded, so single threaded performance should be even _better_ than 58% higher IPC than K10 if you aren't loading the other core in a module! Looking good so far!


Calculations:

Bulldozer: 232 seconds with 16 cores at 1,8ghz
232*16*1,8=6681,6


Opteron: 400 seconds with 12 cores at 2,2ghz
400*12*2,2=10560

10560/6681,6=1,58045977 ~ 1,58 higher IPC
