6970 specs

Lets hope 6870 is slower than GTX 580. That will force ATI into releasing a "budget" performance card that almost matches 580 power, rather than another "expensive" performance card with similar of greater power.

90% of GTX 580 performance for sub £300 will be nice to see. The 6970 will of course beat GTX 580 by a fair margin, but it will also ~£500 at launch making it unrealistic for most people.

I'm here to grant your thoughts true. Are you ready?. The 6870 is slower than the GTX 580. :p Tee hee!.

I know it's a typo but I had to pounce before a fly ninja edit made me look foolish.

I'm not going to speculate on the new cards too much. AMD and Nvidia compete like they always have so it is going to be close. There has been a few hiccups for both Nvidia and AMD through time but today, here we are as they duke it out again.

The GTX 580 is a great card apart from these specs were meant to be for the GTX 480 originally. So although Nvidia have brought out this card first before AMD, they didn't have to leap through hoops of fire to do it. With all the great cards from both companies competing at different price points then I see this ending up pretty close in terms of performance.

It will be close and Nvidia have a strong performer for AMD to come against.
 
Do you guys not read the posts??

The odd shader count is because the 6970 moves to 4 shaders per group not 5, this allegedly makes it 20% faster than a 1600 shader 5870 based on shader count alone because, allegedly, the fifth shader was larger unused

Well they shouldn't read posts that aren't true! The 6000 series still uses 5 SP per group, 16 groups in each SIMD and 14 SIMD's=1120, the 6850 has 2 disabled giving it 960.

I find it hard to believe the numbers. Given that the building block for a card is SIMD's and there are 80 SP per SIMD then I can't see how they come up with a number like 1536. Also it uses the SAME 32 ROP's as the 6800 series even though Anandtech said that one of the main reasons for the increase in performance of the 6000 series was because AMD didn't have enough ROP power for the 5800 series(It also used 32 ROP's on the 5800). On top of that it says that it has 96 TU. Now AMD has used a ratio of 20:1 for SP to TU for the 3800, 4800, 5800 and 6800 and now we are suppose to believe that they are going to increase that to 16:1? One could suggest that it meant that the original chip was suppose to have 1920 SP but that would mean they designed the card to have a ratio of 60:1 in terms of SP to ROP's while their budget card was designed to have a ratio of 35:1- these numbers just don't make sense.

Cayman has different arch to Barts...

It's rumoured to have Vec4 but so was Barts right up until release day. It would be very unusual to be working on too completely different GPU architectures at the same time so until I release I wouldn't be believing anything!

Huh...

AMD have said it them selfs.... that this new Arc is a Crossbread from old to new.... The new one is made for 28NM hence this new 40NM they have now

Where's AMD at, we have Nvidia releasing their new top GPU and AMD are nowhere insight with some performance figures to spoil the 580 party. IMO this could be a sign that the 6970 is not the beast we are hoping it would be.

are you seriously asking where amd are at ? nvidia have just launched the 580 which is what the 480 should have been 7 months ago

1920sp, 30 SIMD groups
30 SIMD groups - that's 64 SIMDs per group - i.e., 4D shaders.
Cayman XT consists of SIX modules, each with one tessellators.


If a new 4D shader is equivalent in performance to an old 5D shader, this would be the equivalent of a 2400 shader Cypress - but with other core enhancements to improve throughput, tesselation, etc (as with the Barts enhancements).

Hmmmm, if this is TRUE it will make 580gtx cry for buttermilk

it likely will drop in price (580) as the 280 did and where buyers had to get reimbursed after the buy.

tesselation fixed, DP, and 1920 4D shader with effective fillrate, well I am glad waiting if that is true.
 
<3 this entire thread.
Can hardly wait for the 22nd November.

I'm just hoping the cards are here for Christmas. My GTX 280 recently broke down with no warranty due to BFG liquidating. So i'm hanging on to my cash for the new ATI/AMDs.

I am happy porter, turn the ZGC
Cayman has 1920SP, 30 个 SIMD Core, and will not be postponed for sale. The official conference for this week

When are AMD going to announce the specs? I thought they were supposed to be announcing it on the 9th?

Is the cayman pro/6950 supposed to launch at the same time as the 6970?

If this is true, Cayman should be a beast :)

I struggle to see how two of these chips (even down-clocked with a few SIMD groups disabled) would work within a ~300W envelope for Antilles, but I guess we will just have to wait and see.
 
I hope these babies will come out before christmas :) GTX 580 looks good upgrade from mine 4850CF, but few weeks might change everything, lets wait and we'll se, 6970 or 580, thats the question :D
