Boooo I want more 20nm rumours :mad:

Speculated perf gains do put it up with/past the titan though...

Edit: strange the 8950 isn't just a cut down 8970...

Diagro · 27 May 2013 at 22:23

So... Do i go Xfire or wait? :/

Freddie1980 · 27 May 2013 at 22:24

Pinch of salt indeed, some of these crappy rumour sites seem to be obvious to the fact the 8000 series already exists.

Boomstick777 · 27 May 2013 at 22:27

HD 8970 6GB,

6GB ! Maybe upcoming games are going to require a lot more vram.. 8970 looks very nice on paper, where would AMD price it against the GTX 780 3GB if it's faster and has double the vram. Tis a high price precedent Nvidia has set with the 780's..

The card I would really like is Nvidia Geforce GTX 880 8GB (Maxwell)

Jay85 · 27 May 2013 at 22:33

Taking with a pinch of salt here but if it is $599 then we're looking at another case of extreme pricing!

Something tells me AMD are trying to confuse the hell out of everybody (indirectly) to confuse nVidia about their plans.

If it's true then, good show AMD

Kaapstad · 27 May 2013 at 22:40

The fact that they are quoting prices means that the article is total rumours and rubbish.

It is hard enough finding out what the retail price of a graphics card will be that is getting launched tomorrow, let alone several months in the future.

I thought the 8xxx series is for laptops only. Some of the responses in the thread hint at being desktop and being able to purchase the gpu itself?

There is a 8XXX series for OEM only, it doesn't mean their can't be a HD 8XXX for the desktop as well. They may choose HD 8XXX or HD 9XXX the name is really irrelevant it's performance that counts.

Look at Nvidia's latest 7XX series, it's almost entirely made up of rebrands but still has new series name. Performance is what matters.. I hope we see something new from AMD soon, stop this price hikery form Nvidia..

Desktop OEM is 7xxx renamed to 8xxx

Mobile is a new 8xxx range, faster than previous 7xxx mobile.

Desktop retail is 9xxx series, very quick indeed and coming out in June-December.

I completely agree

Those specs for the 8970 won't give it a 35% performance increase on the 7970GHz.

TheRealDeal · 27 May 2013 at 23:15

Gcn 2.0 was said to be 20% better than gcn. With the added shaders and a small clock bump it might be in the ball park. Memory speed is also up. It's probably made up anyway but we shall see. If it was 35% faster on a 420mm2 chip it would be pretty impressive. The 8950 looks pretty week to me with 256 bus and 1200 core speed which might not have much room for overclocking.

humbug · 27 May 2013 at 23:37

Less rumours and more hard facts please....

Edit, the fact that they have the 8950 with a 256Bit bus tells me this is horse manure.

Yes by the sound of it NVidia are not the only company rebadging GTX 680s lol.

Based on the assumption that we're dealing with the same sort of stream processors, it could very well be the case that we aren't.

Just to point out that it's a strong assumption there.

However, I don't believe these specs are correct, I don't buy at all that AMD would put the next X950 card on a 256bit bus at all with a different chip to the X970 and less RAM.

You're most probably right about this being fake (who the hell is sad enough to dream all of these things uP?) but tbh I've felt the top tier cards from both companies have been too close to each other to warrant the often ~£100 premium for the faster card

I strongly doubt they will rebadge. AMD typically push new chip designs out for their own sake as kinda prototypes of new chip arrangements and so on, like the way the 5>6 series went.

The 6850, 6870, 6950 and 6970 weren't particularly faster than the cards they were replacing, they were however slightly cheaper and with completely different chips.

The likelihood is that they'll be trialing something new with the next series as a refresh, to then put in to larger production come 20nm.

Not that I think they do it for the sake of the consumer, but to keep their R&D flowing.

Was taking GCN2.0 into account but obviously there could be enhancements that I'm not aware of. I find it very unlikely those specs would give that kind of gains overall tho even in a best case scenario outside of limiting benchmarks to high-res multi monitor setups.
