Mike:
The FX benefits dramatic from clock speeds.

Evenso on my last test i still had 6 cores running on boinc.
It was just a speed comparision between AMD and Intel app not overall speed test.

FX @3.9 GHZ

Also @3.9 GHZ the FX is up to 20% faster as the Phenom on 3.6 GHZ instead of 28% slower.  :o

Bench attached.

Raistmer:
I think those AVX-enabled need at least FFT update if not whole IPP functions used.
AFAIK Joe implemented some hands AVX opt in stock. Would be good if it would be incorporated in opt apps also... USE_AVX macro-governed perhaps.

Yes, definitely looking at that.  Any AVX enabled app should really have the AVX path and at least one viable alternative path/library, since AVX availability must be detected at runtime, and on Windows is only supported under Win7 w/sp1 (or presumably Win8beta)

So far I have managed to build an AVX enabled static fftw lib, both x86 & x64 (which will be useful at least in particular for AP), that uses its own internal detection, but that build is only MSVS2010sp1 so far & will definitely need to bench an ICC built variant soon (supplied bench in fftw project at least),.  So I'll probably try linking it in to AKv8 as well as slotting in your V7 updates & splitting core functions into different SSE base versions.  I'm hopeful when I get going to have that operational pretty quickly.

I haven't gotten around to test linking in several sse level static IPPs yet into the same build, but looked at how to do it & doesn't appear to be difficult.  What I'll probably do is a huge build with every kind of FFT available linked in at the same time, then switch variants with a command line parameter so the testers can tell us which library is faster for which chip  ( :D  let the testers work out the tricky mappings )

skildude:
it looks like Primegrid has an AVX app for their LLR projects for linux and Apple but not currently any windows

cristipurdel:
Are these libraries already included in the amd app?
