Hi

I use AK_v8_win_SSE3.exe this for Athlon x2 ( AM2 ) 1.9 ghz ( 45 W )
and i now i dont know what APP is the best for my Atlhon.  :-[

Hi there,  If you have SSE3 , then the AK ones are definitely faster IMO (but then I don't drive an AMD chip anymore) .  It is mostly the older chips with only SSE (and maybe some SSE2) where the special FFTW build of v2.4 is particular faster.

Try to compare AK of SSE2 and SSE3 versions.
I recived few results that for x86 SSE2 version faster on Athlon 64 (X2 too) than SSE3 one. It's AMD specific, Intel chips go faster with SSE3 if available.

Slawek:
I use in AP SSE3 in my Athlon.. but i have poor results http://setiathome.berkeley.edu/results.php?hostid=4708858&offset=40
 i can change optimization for AMD ? ( SSE ) for  better computing ??

Jason G:
Not recommended for AstroPulse, the SSE3 build is generally faster in all cases where available.  This is an old thread related to characteristics of Multibeam builds.  AstroPulse builds do not seem to follow this pattern (yet).

Poor results compared to what?
