Would be interesting to see how the 6950 and 6970 perform in Milyway@home. The new architecture features some new GPGPU features and it would be nice if the coding people in the project managed to take advantage of these new features to unlock all the potential performance out of it.

Thinking of getting a 6950 to replace my 4890.

Got an XFX 6970 arriving tomorrow will post.

pls post here :-)

Clock for clock a full Cayman (HD6970) should be 20% faster than a full Cypress (HD5870) due to the better utilization in DP and different number of shader clusters. And since MW already ran very efficient (quite close to the theoretical maximum), there's not much room for speedups due to other improvements.

I'll be happy to let reality be the final judge, though ;)

let's wait cncguru's tests.

Looks early next week I'll get 6970 for testing, so this will an answer for me - should I go forward with 6970 or not.

Hey guys I just got informed by UPS that they are not delivering my card until tomorrow! So much for "next day air"
But it will be here for sure tomorrow and maybe milkyway will actually be up so I can test it!!!
I'm really way more interested in the 6990's but just had to get at least one of these!

let's keep fingers crossed :)

when, now it's evident that 6990 will be dual 6950, but the price will equal to two 6970. So, what's the point, bro? :)

When you do post, it would be interesting to hear of the average time taken by each MW work unit and compare this with the time taken by an HD5870.

Longer term the final RAC will confirm these single WU timings and how much more output the new series card can do.

It would also be interesting to hear how quick the HD6970 is on DNETC as well.

Go away, I was asleep

sure i'll post secs per WU on stock clocks and OCed one. For a while there are no way to exceed nor 950MHz nor voltage tweaking, it will not be that "sweat".

Remember, in one review guys wrote about 70 secs per WU for 6970. If we assuming 90 secs for 5870 - not that bad, somewhat 25% boost. Bur I expected more though...

My 5970 can do a wu in 78sec when it has sufficient CPU resources available to it. Other wise it's at 82 to 84 seconds/wu. 938MHz core clock and 900MHz memory clock.

it's water cooled? to jump from 725 to 938 on dual-GPU card - that's not easy, man :-)

Just air cooled...running at 82°C and 72°C on respective GPU's.

not bad at all :-)

I am way stupid busy tonight but I did stop to install the 6970 in a board by itself with the new 12 drivers that came with and set everything to default for now.

Yeah I think I'll get 7 more,lol

Not too bad. Be interesting when you overclock it!

Worth the upgrade from a 48xx series, but might skip changing out my 5970. Unless I win the lottery ;)

so that folk about 70 secs w/o OCing was true :-)

considering not oc'd, not bad times. I usually run two concurrent so had no idea how the 5870 compared.

I did not get the shorter WUs for the test.

thanks for the info cncguru.

[stock 880 clock]
Busy weekend but I will be back to post more details and see how it overclocks. But it is readily apparent that it outperforms the 5870's admirably.
And (at least in the US) it's selling for the same as the 5870's so no first release price gouging which is refreshing!

if you get the time, please provide temps--gpu and vrms temps with voltage (especially oc'd voltage/temps). how noisy is it at load compared to the 5870 reference freight-train-like fan? reviews suggest amd has yet to satisfactorily address the fan noise. thanks.

and I agree the 6970 outperforms the 5870, but that was expected. I expected more of a smack down. amd is apparently more focused on beating nvidia at the price game, hence a better card same price though initial offerings suggest big price jumps already, and not producing the king of the single core cards. many, as did I, expected the 6970 to top the 580, so either nvidia has pulled a coup or amd's focus is not interested in top single core gpu. it is a great card for the money.

thanks again for the info.

A full Cayman (HD6970) is 20% faster per clock than a full Cypress (HD5870), the HD6950 is 10% faster per clock.
