Overclocking the Sapphire HD6850 in Catalyst Control Center is a futile process as it limits the card to 850MHz, however Sapphire sent over a beta of their new Trixx overclocking tool for the HD6800 series.
We need to point out that the version of TriXX shown in these screenshots might look (and act) slightly differently to the final version bundled with the retail product.
We would like to add that the results on this page will not relate to the final product as the Sapphire card we received had 1120 shader cores (see image below), this page is therefore here mainly out of curiousity.
The Sapphire Trixx utility will be bundled with retail versions of the Sapphire HD6850 and it allows the end user to change a plethora of settings, including GPU voltage changes. We managed to get the core to 860mhz without adjusting the voltage.
After cranking the voltage (as we always do!) we managed to get the core stable to 951MHz and the memory to 1132MHz. This is an incredible core increase from 775MHz and although we could just be lucky with this particular sample, it could very well show massive potential headroom with the HD6850 hardware – we experienced similar results with the 960 core XFX HD6850.
Your 6850 have 1120 sharders. o_o”
these are really good cards, love the performance and price.
Excellent boards those, really look the part and performance is awesome. overclocking is great !
Shit… haha 6850 is a killer card and guess what? its right in the price range im looking at 😀
Only thing i can say reading other reviews is that the 6850 reference cooler is pretty weak. These sapphire cards look great for the money 😀 (6850) will reserve judgement til i seem overclocked 6870s
Killer card indeed, couldnt agree more.
HD6870 is good, but I dont like reference designs, too noisy/hot/ I will wait for sapphires or XFXs custom cooling one.
HD6870 is the one I would get, but not reference version. will wait a month for vapor X or toxic version.
6870 reference design is a waste, waiting on other solutions
the hd6870 isn’t my first choice until they get third party products out of the stable,
Its always the way with launches, but its weird AMD have let their partners make third party solutions for 6850s
over clocked HD6870s might be hard to get out the door with such poor over clocks on the core. seems both boards max out around 950
While these cards aren’t awe inspiring, when you look at the price 150 for a 6850. about the same as the 5770. 25% more performance, looks good.
those overclocks on the 50 are great. id say overclocked versions will be out really soon. vapor x anyone ?
As JC stated, this 6850 has 1120 shaders instead of the default 960…
The bottom gpuz screenshot is for the 6870
I get the same 3dmark vantage score as this HD6850. I was hoping I might even up with a 1120 shader version but sadly not 🙁
@ Jon
I saw in another review that they managed to get the Sapphire 6870’s core clock to 1000mHz stable. I’m sure if put under water, these cards will have a bit more overclocking headroom anyway.
