I will give you my result when I return home.
But I see blackosx also beat me in Furmark test
So 5770 > 6670 :huh:

Hi Slice

Looking at: http://www.hardwares...rison-Table/131

I see these differences between the 5770 and the 6670.

Yep, but there are DDR3 & DDD5 VRAM & different vram clocked versions out for the AMD 6670 - also make up to 50% diff in gaming speed on same gpu type!
The value Memory Transfer rate (above list) 76.8 GB/s for the 6670 is only for the DDR5 version!
The 6670 DDR3 (900 MHz) version has only 28.8 GB/s - and also much slower general performance then the older AMD 5770 DDR5.
Because the other main speed parameters, pixel fill rate & texture fill rate is much higher for the 5770. Both values, together with the memory speed, corresponds to the main OpenGL/DirectX speeds.
But its getting even more complicated in this AMD 6670 case :weight_lift:
Beside the DDR3 vs DDR5 AMD 6670 versions, the different manufactures also clocked gpu & vram very much different.

6670 Memory clock (DDR3) versions: from 600 Mhz up to 900 MHz (900 Mhz = 28,8 GB/s, 600 MHz is around 19 GB/s vram speed!!)
ASUS + Gigabyte OC 6670 DDR3 clocked 900 MHz(vram) others mostly 800 MHz, some only worse 600 MHz or 667 MHz!
GPU clock is mostly 800 (only a few 820) so major diffs in VRAM MHZ, not in GPU MHz.

6670 Memory clock (DDR5) versions: in difference to the wide vram MHz range of the DDR3 versions, DDR5 versions are mostly same clocked (1000). No or very less vram clk diffs between different manufactures.
So even benching same main gpu type AMD 6670 , you will get mich different speeds between AMD 5770 DDR5 (850/1000) and an worse case AMD 6670 DDR3 (800/600 MHz)! (GPU clk/Mem clk)
So VRAM speed of the worst case 6670 version is only 1/4 ( 77 GB/s vs 19 GB/s) , major OpenGL functions 1/3 - 1/4 of the AMD AMD 5770.
Back to valley bench: Because Valley using often & much vram , vram speed will matter much more than in "normal" games.

Great site for comparing lost of GPUs (main features, main speeds):

http://www.gpureview...1=615&card2=656 AMD 6670 DDR3 vs AMD 5770 DDR5

Example to not get blended by higher major AMD numbers:
http://www.gpureview...1=579&card2=656 old AMD 4670 vs new AMD 6670 DDR3 = no / very less OpenGL speed benefit for the much newer modell 6670, only some (15%?) faster gpu computing / shader capabilities

You can select other gpus also - very useful before buying some new gpus.

My card exactly is
Gigabyte GV-R667D3-2GI
DDR3, 2Gb, 800MHz

But I don't know why I had so bad result in Lion. Today I tested with ML and the result is much better

My be there is influence of other tunings.

Now it is comparable with blackosx's result and lower as it should be. -_-

And for comparison OpenGL Extension Viewer 4.0

Very strange. Instead of seeing trees and valley I had seen black background with very small coloured squares

"Very strange. Instead of seeing trees and valley I had seen black background with very small coloured squares" AMD user



Yep, well known Problem with AMD and having multisampling (AA) active running THAT bench. Same happen with Heaven bench.
Set AA off (x0) , by using BASIC preset (or any other PRESET) values but switch AA always off.
Nvidia cards are not effected by this problem.

@Alex009988: deactivate AA for ATI graphics.

OpenGL Extension Viewer just crashes every time I try to run the OpenGL 3 tests. Any idea why that happens? Every other graphics test I've tried works fine.

Update OpenGL Extension Viewer. Or just download more recent version.

It is the latest from the AppStore, version 4.0.8 (7). Really strange but I suspect it's just the app, I still haven't bumped into another one crashing because of OpenGL.

@blackosx: you seem to have the same graphics card I have, can you run OpenGL Extension Viewer's core tests?

I tested OGLV also with Core setting / Nvidia 9600 GT. Crashes also.
I am sure with OS X up to 10.8.2 it didn't crash using that core / 3.1,2 OpenGL tests - only 3.3+ wasnt benched because my gpu hasnt the features.

Perhaps some prob with 4.0.8 & 10.8.3 - homepage shows 4.0.10 - http://www.realtech-...ew/download.php

but the App Store wasnt already updated (stays at version 4.0.8) - no other way to get the download ;)
Same happend with version 4.0.9 - Feb 2013 - never came up in the App Store. Perhaps Apple has some problem with that?
Or works Apple very slow updating freeware stuff in the app Store - no money to get ?!

v4.0.8 from the App Store crashes for me also if I run the core tests.
v4.0.0 works with the core tests.

EDIT: v4.0.0 file from link removed from my dropbox

Hello guys,

Here are my results, the specs of my "mac" are in the signature.

[BASIC]
Quality= Medium
Stereo 3D = Disabled
Anti-aliasing = Off
Resolution = 1280x720


[EXTREME]
Quality= Ultra
Stereo 3D = Disabled
Anti-aliasing = Off
Resolution = 1280x720

Thanks, that one works. So it was the app after all, I suspected that much.

@mitch_de: I've noticed the crashing issue with OGLV since 10.8.2 but it was probably due to the version from the AppStore (it's dated 27/09/2012).

Hmm, my version also is 4.0.0. The best version?

Version diff is MOSTLY only adding new Mac Modell identfier and (less) changes in the html result layout. So no major code changes for the benchparts itself.
For result i think version doesnt matter - so as longs as the bench results stay compareable its no prob to use older version.

Results with build 12E30 and unmodified presets Basic and Extreme, both with AA:
Attached File  basic.png   63.33KB   3 downloadsAttached File  extreme.png   63.77KB   3 downloads

According to barefeats the 7950 reaches an average of 33 fps with preset Extreme, so my result seems right.
