Hi, as we see most of the common OpenCL Benchmarks stopped working with 10.8
And even if they work (not fail by Init / Build erros) results fail.
EDIT: I attached the Displacement (fluid simulation) OpenCL benchmark (FPS). Use S to switch between 2 modes
Usage: Start terminal, cd drag&drop folder of the app into terminal ENTER, drag& drop app into terminal ENTER


So i compiled (old ) Galaxies again, removed VSYNC and compiled for 10.7 + 10.8
Works here for me even with 10.8 , but may fail with other gpus running 10.8.

Usage,  very easy: Galaxies starts up in GPU Mode, you can switch by key s to cpu single / cpu multicore and back to gpu only. ESC quits
The mode change (key s)  takes some time - mostly a few seconds !


Info: Galaxies uses the number of 65K (65536) as default for the star count.
The more stars the more cpu+gpu load.  Fast gpu may get a bit more Gigaflops if they use more stars , use 81920 or even higher

262144

, than default.
HOW TO CHANGE NUMBER OF STARS COMPUTED (may increase GigaFlops):
start terminal
Finder show package content on Galaxis
Drag & Drop galaxies  (black icon) in terminal
81920 ENTER (be sure to have an space between galaxies and the 80K number, max is

262144

Slow gpus may not get any more Gigaflops by increasing the number - but the simulation itself will be shown very slow - takes much time to see the nice star movings.
You can use in this case better 32768 , which speeds up the simulation compared to the 65K or 80K.

Galaxies, as OpenCL bench takes much cpu load - so i recommended in the past better use Luxmark or OceanWave (both stopped working with 10.8) for OpenCL benching.

Great! LOL - HUD speed needle is over the limit   - at the time, apple developed galaxies 256 GigaFlops seem to be enough for the speedmeter hud.

i'll post screen later but with an HD 6870 1024Mo i got 616 under Lion and 555 under Mountain Lion

Great ! GTX 580 now pole position with 726 GigaFlops
Have you tried to increase the count of stars (read first post) from default 65K to 80K ? Maybe even a bit more gigaflops possible
Also your result for 10.7.x maybe interesting (should be around 10% faster, like for others)

Thanks!
Updated Galaxies: (DL first post)
- Gigaflops Meter now skaling for an max. 1024 Gigaflops
- shows number of stars (bodies) computed right of the gpu name

mitch_de,

Did you go back to the newer hwsensors with the newest version of fakesmc?  I know you said it was messing with your speedstep and temps or something?  Was it also affecting your graphics performance?  Anyhow there were some changes made to it since then have you tried it since?

I left you a post over there you never responded?

Thanks

[mitch_de]

Speedstepping works for me.

[gorg]

My 5870 in Snow Leopard 10.6.8 got 860 Gigaflops.

[amf5]

EVGA 8800 GT: 227/231 Gigaflops (GL renderer/software renderer, 81920 bodies), 219/226 (65536), 189/212 (32768)
Q9550 @ 3.0GHz: 54 to 53 Gigaflops (number of bodies doesn't seem to matter)

This was on 10.7.3. Interesting that the software renderer with lower body counts is more than a little faster

[mitch_de]

Addded some iMac 2011 results.
Indeed, stars count doesnt matter for CPU, because only 2/4/6 cores vs 16++ gpu units. Low cores count limits better gigaflops by more parallemism.

I dont habe any HW plugins in use anymore, ony FAKESMC.

here i am!

mitch_de, you are the best!!
thanks for this, i been long time waiting,
have a nice day man.

Update: I attached the displacement OpenCL benchmark (should work on 10.8 too)
