The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
The customised solution on the HD6850 delivers great results, with a maximum peak of 60c when gaming. Furmark pushes the core 9c higher, although the fan is very moderately paced, more on this shortly.
The HD6870 is a reference design with the standard AMD cooler and as such gets a little hotter. The results are still very good however, reaching only 65c when gaming.
Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.
The improved cooling solution on the Sapphire HD6850 means it can return to idle in 15 seconds, 7 seconds faster than the reference HD6870 cooler. When Sapphire get the chance to enhance the HD6870, we can expect low temperatures and a faster return to idle state.
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.
