AMD 9*** series soon?

If these rumored specs below are legit (Doubtful) the 9970 would be an absolute monster..

If you compare these numbers to the HD 7990 specs you can see where most of them came from.

I WANT SOMETHING AFFORDABLE AND AMAZING FROM AMDDDDDD!!! Haha, waiting game is killing me.

If it's a big chip with 4k stream processors and a 512bit memory interface then unfortunately it won't be affordable But it will be amazing

Affordable or not, I'm having it if it is that spec

Max i will pay is £450! As thats what i paid for my 680 on release! No way im going higher than that.

That chart is miles off.

Apart from the immense number of SPs, which isn't realistic on 28nm, having a 512bit bus with 5Ghz GDDR5 would be ridiculous. You would get better bandwidth from 384bit at 7Ghz (which is more than attainable) and do without the extra expense and complexity the 512bit bus brings with it.

9970 @ £400.00 and maybe I will get 2

This seems to be the source of the specs:

Depends, die stacking is still realistically too expensive with too low yields to be financially viable for something like, sticking 2 x 7970 dies into one module with insanely fast on die communication. Interposers are RIGHT on the brink of becoming mainstream, vastly cheaper, vastly easier, still offers insane bandwidth/communication latency. Putting 2 350mm2 cores together with a pretty cheap interposer would prove massively cheaper than making a 500mm2+ core because yields increase hugely.

In terms of TDP, people don't seem to understand it. You can take a 780gtx or a 7970 and give it a tdp of 100W, it would simply throttle down under heavy usage to not use more power than that.

Its unfortunately quite easy to make a seemingly absurdly powerful chip, seemingly awesome peak performance, a great clock speed.... then whack a low TDP on it and cripple the hell out of it making you think you're getting something better than you are. Have you seen 4.5W SDP Haswell's.... they'll be throttled to hell and slow as crap, but the nice high looking speeds and specs will make people think its fast.

I'm NOT saying that is what AMD has done here, but just pointing out that TDP itself is irrelevant, its VERY easy to mess with TDP to create new products that seem more viable.

The reality is AMD is working exceptionally hard on power saving tech, read up on Richland, Jaguar. AMD's focus for the past 4 years has been dropping power and don't forget that the 7970 is functionally a architecture that was designed 3-4 years ago. Richland significantly improved power efficiency, performance, and dropped overall power usage all on the same process. There are loads of ways to improve power usage on the same process over the space of a couple years.

My personal take is to have 4000 shaders, process tweaks, design changes wouldn't make GCN capable of doing 4000 shaders on 28nm with a 255W TDP, they may have changed the shaders significantly for all we know, or it could be ultra early 20nm production at GloFo.

I know im saying im waiting for something affordable from AMD but realistically im actually wondering how long my gtx 680 will last before it dies (not because it's on its way out). As we know a lot of people use the sale of their current card to pay towards a newer and better card so in a way if mine dies before then, then im looking at paying full price rather than say knocking £200 off meaning an upgrade of around £250 instead of the full £450!

This waiting game just doesn't help people that might be thinking the same as me.
