For overclocking today we used the excellent Sapphire TriXX software tool, which we use for all our AMD based discrete reviews.
Above, the HD6790 DD, HD6870 DD and HD6950 DD.
There is clearly some decent overclocking headroom with all three cards, averaging around a 8-10% increase depending on the model.
If you make the effort, there are considerable performance gains available with a little manual ‘tweaking'. Temperatures weren't affected on any of the cards as we didn't need to increase the voltage settings at all.
Very nice indeed, HD6870 is by far b est value, thats a bargain.
Excellent, I agree HD6870 is best and its very well priced. I dont get paid for 2 weeks sadly 🙁
Thought they had vanished off the face of the earth there for a while. nice to see them back … with a bang.
Never mind the 6870, the 6790 is really more than most people would ever need, quite surprised how well it performs even at 1080p. But for the small price increase, 6870 is much better value.
Very good, thanks for review.
I like XFX< always had good luck with their cards. shame they stopped the cool X shaped boxes they used to have.
are they the first to have used a direct touch heatpipe cooler like this?
Two of the HD6870s seem best to me, just a little more than one of the 6950’s.
They should lower the 6950 price to £199 inc vat IMO or even £190.
Great review man, im really looking at one of those 6790s for my media center, but it seems poor value when the 6870 is only 25 quid more.
6870 FTW. those are great cards. XFX DD version is a bargain, orfered one.
really cool. And the price isn’t really bad…
