AMD 6xxx performs really good with OoenCL - hopefully sometime more apps use OpenCL for things like videoencoding or audioplugins.

Hi,

I saw Lightning in the first post so here i am

832 MHZ, 2600K, 10.8


Score 1435 ; is it good ?

Yep very good!
Only new AMD 7970 can get significant more: around 1950 in sala scene!!

Today installed Gigabyte HD 6870 (into MacPro2,1 with Mac OS X 10.8.2 with Chameleon):

Interesting to see the steps up by new AMD/Nvidia gpu computing power by focus on better+faster gpu computing hw-design.
AMD 4870 : 202
AMD 6870 : 608
AMD 7970 : 1990
(all example results scene SALA (medium)

Same happens on Nvidia. OpenGL speed isnt the way faster (10 times AMD 4870 vs 7970) as gpu computing diff.

One more interesting observation

for my 2001th post I give you:

Then when we add the CPU running at 3.8ghz and we:

Go down? I hope that speaks highly of the GPU and not the other way around...

nope, something's wrong with CPU, too be continued....

[mitch_de]

using OpenCL GPu + OpenCL CPU isnt very usable! Normally OpenCL Apps (or better - some tasks of the app) run gpu only , otherwise CPU has too much to do, because the CPU must (even running OpenCL gpu only) lots of things (cpu load) to communicate / fill/ receive  gpu with data. The more complex the code and faster the gpu the less usable is GPU+CPU compared to GPU only.

Damn, someone snuck in my room last night and swapped my reference 7970 for a Ghz addition. They must have been gone in a flash cause I didn't see nothing

Overclocked?

Yep!

http://www.luxrender...op20/Sala/GPU/1

For even more OPenCL power up to 8 GPUs are needed.

just with Ghz edition BIOS flash. I mucked around a bit with a few settings in the ATI7000Controller.kext, had Clover load the ROM from seperate file, running newest 10.8.3 beta, but still hard to account for the huge performance jump.

Strange.

faster cpu (RAM), even gpu only OPenCL also makes little diff in OpenCL speed.

[eep357]

The number of compute units and core clock for that 580 right? 1800mhz?
