#DOWNLOAD DRIVER XFX RADEON HD 6850 SERIES#

I bought a HD6850 on friday, and it arrived yesterday. I always rely on my own testing for accuracy. Too many conspiracy theories for my liking. Maybe if they actually spent less timeįaking review comments and tested all the products they received people It’s not the first time as most enthusiasts know. i.eįace it, Kitguru messed up and then tried to cover their tracks, badly. XFX 6850 review where the “960” card matches the “1120” for performance. What makes it worse is that the results were clearly copied over into the On the memory, the HD6850 is outscoring the reference clocked HD6870.” What part about this mentions the shader error?: “These increases are hugeĪs the figures show – with the clocks at 950MHz core and 4560MHz effective Top of that, the GPUz on that page shows the 1120 shaders still (oops!). The 6850 OC beating the 6870 which only happens on the enhanced model. Overclocking for example, clearly done on the Sapphire 1120 card as it shows Problem is that the performance in the article was wrong. Shader issue (after launch as there was no mention in the original article)Īnd photoshopped the GPUz uploading a new pic. Processors and the performance of that card. Kitguru published their Sapphire article, their GPUz showed 1120 shader Maybe there’s a bug in TessMark, or in the OpenGL driver of Catalyst 10.10 or in the measure… If someone has a clue, the comment section is there for you!įacts? Not a word normally associated with Kitguru. But I stop here because I don’t have a HD 6850 nor HD 6870. This score should be higher like around 16000 points in moderate tessellation. Actually, seems there’s a problem in the TessMark score of the 6850 HD with 960 shaders.

a Radeon HD 6850 1120 shaders with a core clock of 900MHz would have a score of around 8220 points: the score is not too far from the HD 6870Īt first sight, the scores of the Radeon HD 6850 with 1120 shaders look normal.

a Radeon HD 6850 1120 shaders with a core clock of 875MHz would have a score of around 7990 points: the score is a bit above the MSI R5770.

In normal tess level, MSI R5770 Hawk gets a score of 7515 points, whereas the HD 6870 scores 8342 points.

a Radeon HD 6850 1120 shaders with a core clock of 900MHz would have a score of around 21700 points: the score is not too far from the HD 6870.

a Radeon HD 6850 1120 shaders with a core clock of 875MHz would have a score of around 21100 points: the score is a bit above the MSI R5770.

Let do some linear math for the moderate tess level: The HD 6850 has a GPU core clock of 775MHz. I just received from Zardon, the guy behind KitGuru, the TessMark scores for a Radeon HD 6870 (1120 shaders, gpu core: 900MHz):

table, here are the score of some Radeon HD 5000 series in moderate tessellation: Don’t ask me why, I currently have no HD 6800 series in hands so I can’t test TessMark to see how it behaves with HD 6850 / HD 6870.įrom TessMark comp. But in moderate tessellation (factor X8), the difference jumps to 36%. In normal tessellation mode (which correspond to a tessellation amplifation factor of X16) the difference is around 14% which sounds normal. In TessMark 0.2.2 (OpenGL 4 tessellation benchmark), it’s another story.

ShaderToyMark: HD 6850 with 1120 shaders score ShaderToyMark: HD 6850 with 960 shaders score ShaderToyMark is nearly a GPU computing application!Īnd guess what? There is exactly an increase of 16% between both versions of the HD 6850 (see the chart above). Most of shaders used in ShaderToyMark are math shaders (few or not texture fecthes at all). ShaderToyMark is a pure and really intensive pixel shader test. KitGuru has published a comparative article between HD 6850 with 960 shaders processors and HD 6850 with 1120 shaders processors.Ī radeon HD 6850 with 1120 shader processorsġ120 shader processors means 160 scalar processors in more or an increase of shader computing power of 16%. ShaderToyMark + HD 6850 (9 shaders processors), sourceĪs you may know, some Radeon HD 6850 have been sent to the press with 1120 scalar processors instead of 960.
