AMD 9*** series soon?

That's interesting they are suggesting that the 9970 will have a 512 bit memory bus, so we get to have the arguments all over again with 384 not being enough :D

512-bit memory bandwidth would imply an "all out performance" card. A 512-bit memory bus is tricky to work with efficiently, and leads to increased manufacturing costs. Not something that's going to be a popular route unless it's absolutely essential.



Besides, that entire link smells of BS. 4096 SP? Not likely. Not likely at all. Without some massive change to the nature of the shader pipes, a 4096 SP GPU would be really huge (at least 500mm^2), and I can't see AMD going down that road right now. That's a monster chip to produce so late in the 28nm cycle, for such a small market. I expect the 9970 to be about 2560SP, 384-bit, 3Gb (perhaps with a 6Gb version available), and to be about GTX780 performance or thereabouts (clock speed will determine exactly where in the 780 -> Titan performance spectrum it lands).

Those specs are not realistic until 20nm arrives. Even then - a 512-bit memory interface would be a drastic move.

They use to say that computer power would double every 18 months but it seems thats nowhere true anymore sadly. Guess we will have to get use to 20% at the most every 18 months.

I agree, not something you can expect from the current fab. Small increase on what's currently available is likely.
 
There's going to be another cycle on 28mm. It's far too early and expensive to go to 20/22nm, and there isn't going to be mass capacity till the middle of 2014 at the earliest (and that assumes the Fabs don't have problems like they do every time).

That's because improvements slow as they start to get towards the limitations of what silicon can do. Hopefully someone makes an advancement with graphene in the near future, I think I saw something on a program though that said they're not even sure if it's possible to make computer chips with it.
 
Gordon Moore's quote was about transistor count, Martini is right.

Also he founded INTEL which has their own industry-leading fabs. AMD must rely on TSMC, who do not have 20nm capacity on offer because it is taken up by Apple and nVidia. And Intel's slides like to claim Moore's Law has been overtaken anyway. :)

I would not take any of it seriously

Check out the TDP of 255watts and then the rest of the specs don't make sense anymore.

Unless its on beyond3d, I call fake.

GPU's are ridiculous right now for price/performance and progression.

Agreed ^^.

This is why the sooner AMD get something new out of the gate the better. Hopefully the 9970 can compete / beat the GTX 780 so prices get disrupted.

One good thing I noticed recently is that PCI-E 4.0 is going to be part of future platforms. With the way desktop development has slowed down I was worried PCI-E 3.0 would be the final standard before Dedicated GPU's got replaced by APU's. It's nice to know that at some point in the future GPU's will be so powerful as to saturate PCI-E 3.0's bandwidth. Maybe when 4K gaming is more mainstream. Then we will see some big jumps in Graphics cards performance. Atm everything seems to be very incremental, slow progress with power use taking prioity over everything else.

For now the GTX 780 remains unchallenged, and at it's RRP very overpriced. Hopefully AMD will change all of that soon.
 
It is going to be so funny if AMD launch these new cards and price them according to their performance making the Nvidia counterparts the cheaper option.
