Re: further improved phatk OpenCL Kernel (> 2% increase) for Phoenix - 2011-07-03 July 06, 2011, 10:12:04 AM #37 Quote from: hugolp on July 06, 2011, 05:13:15 AM Quote from: techwtf on July 05, 2011, 11:50:56 PM

5870, SDK 2.1, 11.6: no change, 419->419

Since most gpu miners are using now the phatk kernel you should upgrade to 2.4. Phatk kernel is optimized for 2.4. You will get better results.

Well, you may get better results. For me:



SDK 2.4: 393.7 -> 396.8

SDK 2.1: 399.4 -> 399.4



That's for a Sapphire HD5850 Xtreme 970/300@1.0875V using catalyst 11.6 on Linux and phatk

VECTORS BFI_INT FASTLOOP=false AGGRESSION=14 WORKSIZE=256



Definitely try out both SDK 2.1 and SDK 2.4 though. If you are using Windows there's also an early version of SDK 2.5 with catalyst 11.7 which may be worth a look.
