SSE4+ CPU/GPU app?

(1/4) > >>

Jason00:
With the realease of the I7 processor it has SSE4.2 instructions. I was wondering if anyone was working on an optimized app for that instruction?

Or atleast the SSE4.1 instruction for the combo CPU/GPU instructions? Or is there not much difference between the SSE3 and SSE4 apps?


Thanks
Jason

There is SSE4.1 build for AK_v8 but on some hosts it shows less performance than SSSE3 one. AFAIK there is no specific SSE4.1 made by hands there, only rebuild with compiler and libs SSE4.1 support.

ADDON: Moreover, AFAIK most of current opt app devs don't have i7 hardware available still. And it's extremely hard and ungrateful job - to optimize for target platform you can't access.
So, most probably high SSE levels will wait some more.

Jason00:
Ok, I was just curious. Thanks for the very quick reply!! So most likely its just better to stick with the SSE3 builds. THanks

Jason G:
At this stage it appears, due to radical architectural differences & embryonic state of i7 related SDKs & documentation, that the SSE3  (That's two S's, not three) may perform  better on i7 than either SSSE3x or SSE4.1 builds. As they say "Your mileage may vary".

Give it a go  :D

Jason00:
So would it just be a matter of modifying the app_info.xml file with the name of the SSE4.1 file and of course pasting that file in the Seti directory?
