Tested on Linux and ATi Radeon HD 5850. AMD APP SDK 2.7 in system with Catalyst 12.4 was installed manually. Cg Miner 2.4.1. Core Peak - 750 MHz, Memory Peak - 250 MHz.

Driver SDK Perfomance

12.1 2.6 301.9 Mh/s
12.4 2.7 298.5 Mh/s
11.11 2.5 307 Mh/s

Why not keep the same drivers and update only the sdk? That'd give a better indicator.

I doesn't tried. Do you mean Catalyst 11.11 and AMD APP SDK 2.6 or 2.7 (libOpenCL.so.1)?

I think it's tiny difference (~0.7%), and I'm still testing the stability of both drivers.

For me, stability is more important than performance.

I think AMD has tweak some settings toward 7970.

....

7970 with Freq/Mem as 1125/975

Driver	SDK	Performance
12.3	2.6	660~666
12.4	2.7	655~661

That's what I was looking for. So even with a 7xxx series card the new version is still slower? Is this an SDK issue, or you think it's just that current kernels are not written for 2.7?

I also use CGMiner. What kernel was this? Phatk? It was my impression that if you have to use 2.6 on a 58xx card, diablo was better than phatk.

The fact that it doesn't give amazing results on a 58xx cards doesn't surprise me, and it's kinda why I havn't upgraded myself. Anyone with a 7xxx card tried it out?

Sapphire 5970's, core: 785mhz memory: 503mhz. Its a bit undervolted.
i: 8

I just noticed that version 2.7 of the AMD APP SDK was released last week. I was wondering if anyone's downloaded it, and if they've seen any performance increase/decrease when mining?

I'm only using 58xx cards right now, so I doubt it'd be worth it for me to upgrade (still using 2.5). However, I plan on buying a 7970 in the near future, so I'm gonna have to upgrade when that happens, and I wonder if this is better than 2.6.

Thoughts? Speculation? Personal experience?
