Wanted to try the new large pages function in the 2.6.38+ kernels. I did this on my EeePC 1000HE.

The performance improvement hovers right around 1%; negligible. It didnt affect TF at all.

There is a way to have a sustained clock speed (mine is 5.1 GHz on the i5-2500K) for 24x7 operation but it works best for chips with no hyperthreading, or hyperthreading turned off in the BIOS.

Default New Sandy Bridge PENTIUM G620T 35W TDP

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!!
See: http://mersenne-aries.sili.net/throughput.php?cpu1=Intel%28R%29+Core%28TM%29+i5-2500K+CPU+%40+3.30GHz|256|6144&mhz1=2159

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"?

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.
