More 6970 slides

According to the slides, the NDA expired today, I wonder if that NDA expiration date was set before they delayed the chips?

Anyway, on paper these look like very exciting cards (And I am an NV fanboi). Can't wait to see if these cards are as good as they look. Power might be an issue though.
 
What I don't get is all the TBDs in the slides, wtf?? This is supposed to be the info released about the 6970 when the NDA is up and some key specs are still under wraps?

Yes NDA was today but got bumped to mid December

If they give out slides with exact specs a month ago, someone leaks it, specs are known, they'll send out "final" slides at the appropriate time, current slides make it more than possible to write up a review and have a look/familiarise with the architecture.

As I might have pointed out to Duff-man, exactly what those slides say, the simplified shader structure enabled a far more simplified schedualer and "extensive reuse of core logic" IE, the shaders themselves take up less space, but because every shader is identical, core logic to control them becomes smaller.

Other slides have leaked suggesting 30 simds, 64 shaders per simd, 1920 shaders altogether, which will be pretty extreme performance wise, you're talking over the 5970 +20% shaders, which are +20% faster or so. A 4d shader is supposed to give essentially the same performance as a 5d shader, so 4 new shaders = 5 old ones. So we could be looking at 40% give or take just from that, better tesselator, better front end, improved rops, how much they might improve performance would be a complete guess.
 
I'm expecting it to be ~GTX 580 performance, I think the delay is all about little tweaks to power and clock speeds so it ends up being just enough faster than 580 to claim the single GPU crown (~5%).

You can talk about over 5970 performance all you want, AMD place it behind the 5970 in performance, looks like 580 speed to me.

Pretty sure it's a typo...and you meant "6970".

So they wish to claim the fastest single GPU crown at the cost of overclock headroom that people should have in the first place, AND possibly at a higher price too...?

So would you say the 5970 is consistently faster than the 580? I'm sure I've seen some people say that the 580 is faster but they were probably wrong!

5970 win more lose less comparing to GTX580 if we are only talking about frame rate numbers on benchmark results, but you have to bare in mind that single GPU card will be smoother than multi-GPU card at the same frame rate, and multi-GPU do not always scale well with games. I've seen people happier with their GTX480 moving from a 5970 and Crossfire 5850/5870.

I reckon it'll be very slightly under 5970 performance, but only just and only due to low clocks. That'd be ace because it would a great card to buy for clocking! :D
 
Depends how AMD perceive the 5970 performance to be against the 580 doesn't it really, they don't go on your perception of performance.

Good to see some slides :-)
 
the surprise will be, the 6970 being cheaper than the 580 on launch. performance-wise it will definately be below 5970 and close to 580. The question now is, wot else can the 6970 offer besides performance.
