Don’t count the SPs 320 vs 384
Count the shaders or the SIMDs 20 vs 24
And yes ROPs (render Back Ends) will be 2x the performance of Cypress
Yes, the slides said they doubled the functional ability of each ROPQuote:

If last rumors are true, Nvidia will sell a lot of GTX570 :rolleyes:
Maybe those SMs are super SMs xDDQuote:

Looks like it's going to be a 6950 for me then, GTX 570 a bit too expensive atm.
And i can easily see how 1920 SP's could get thrown in, as generics_user said.
~20 % increase in shader power(minus the small inefficiency in rare cases of high ILP), "double the functionality" of ROPs. Doesn't sound that bad. However 50 % increase in shader power would've been way better. But guess AMD knows better. :rolleyes:
i hear that 6970 is close to 580 .....
if 1536 sp is true, then a cheap 5870 will be better choice than a 6970 for boinc users like me.. mw, collatz and dnetc is already a lot faster with vliw5 sp mArch..
I have to say, no idea anymore what to expect from Cayman. In otherhand it is clear fact that Cypress was highly inefficient design, remember double shaders but only ~60% more performance compared to HD4870 (if memory serves, feel free to correct if wrong]. Same happened on HD4870 vs HD3870, performance increase was not straight up comparable to shader increase. Basically that leaves :banana::banana::banana::banana:load of room to improve. I would say +40% to Cypress if they can find all bottlenecks and figure how to remove them. I believe it can then "trade blows" with GTX580. That would leave room for Cayman Pro at +10-20% over Cypress. But there is lots of if's in that.
Regarding complaints about die size, power, and shader counts: Remember that this ASIC was never supposed to exist on 40nm. They're just doing the best they can to deal with the target process having become unavailable.
Unless HD6970 performs quite close to GTX 580 for that amount of money (450-450$), it is better (performance/ price) to get 2xHD6850 and enjoy performance level of the last ;)
BTW here is a short teaser

Caymen die the size of a gf104 with the performance of the gf110? Ouch!

Price is about the same as nvidia counterparts :D
5 freaking long days and this would be put to rest.

Hi there
All I can say is they are bloody fast.
For the money I am amazed.
I can see this launch being hugely sucessul for ATI, easily on par with 58xx series but better because I literally have enough stock to prevent running out which will also mean our pricing will be excellent and I should be able to keep the price low low, no price hikes.
It can't be right! He said ATI, not AMD! :p: :D

I hope so. It would be great to see a well done launch (without shortages/price gouging), they are not as common as they should be.Quote:

the US government should learn a trick or two from AMD on how to keep stuff secret..
maybe breaking their nda means a fate worse than death and listening to Justin Bieber ?
I think AMD listened a bit from Nintendo. No one in hell can leak any Nintendo future consoles data (remember revolution specs or the "what kind of controller it will have").
