Hi !
-------------------------------------------------------------------------------------------------------------------
Here's just some perf data on the new Sandy Bridge Pentium:

Intel(R) Pentium(R) CPU G620T @ 2.20GHz 35W TDP (System ~40-45W)

Please compare with the specs of an Intel Core i-5 2500K @ 2200 MHz (single thread perf)! Striking!!

Here is the actual comparison between the two CPUs. At the same clock speed (2160MHz), other than a small difference between 1MB and 3MB FFT sizes, performance is nearly identical.

What means the "B" in "FFT size"?

David

PS Please my German word-ordnung excuse

Das "B" ist für "Byte", und der "M" in der infrontovem platz ist für "Mega". Also, wir haven der "MegaByte".

...Sorry, got caught up in the spirit of pseudodeutch

Was that even your question? The only place I see "B" is in my above quote about 1MB-3MB, which would be 1024K-3072K FFT sizes (or 1048576-3145728 if you prefer), as illustrated by the attached graph.

Jawohl. Ich habe already das alle gotten. Aber ein Bischen FFT nein = ein Bischen whatever ist fur "memory" zee Deutch (Ich vergesse). Nicht Wahr?

PS Ernst has been giving me some private tuition recently!

PPS I didn't the Krieg mention.... well I may have done
once, but I think I got away with it.
