just rumor's and hearsay,but I have every bit of faith in amd atm
Titan is a fantastic card though,im not knocking it at all im just curious as to what amd have to answer it
It all depends on how good gcn is as amd seem to pull lots of gains from this architecture at will lately. Most reviews show titan as 25-30% better than a 7970ghz edition. If amd have improved the architecture and then beef up the card i don't think they will need to go any where near titan sized chips to get near or past titan performance. Everything i have read seems to say nvidia were having a harder time producing gtx680 chips when comparing to amd on the bigger 7970 chip. Its all hearsay but amd did launch first with a bigger chip.
Its a big ask from amd as i don't think they will go anywhere near a titan size chip but looking at past history its possible aka 9700pro which was way superior to anything nvidia released at the time.
Amd have been full of surprises lately but a titan beating chip at normal pricing would be staggering. Here's hoping as i will be looking for a new gpu sometime this year.
The thing with the Titan is it has been a great marketing success, every time the word Titan is mentioned all logic goes out the window. The question has been asked a few times "Titan or GTX 690" and the answer comes back "Titan", this in my opinion for resolutions below 1600p is a bad choice. Most people who answer this question have never used both a Titan and GTX 690.
If I was in AMDs shoes and wanted to really top the Titan, I would go the Dual GPU (rather than one huge GPU like the Titan) on a single card route. If they were to put 2 x top end 8 series GPUs on the same card with hardware support (like the GTX 690) to deal with microstutter, no more than 4gbs vram per GPU and sold them for £700 a go backed by a good marketing campaign. The difference in performance between the HD 8990(for want of a name) and the Titan would be staggering.
The one thing NVidia can not do is put 2 x Titan GPUs on the same card.
From AMDs point of view, who cares if the fastest card in the world by a mile has one or two GPUs, think HD 5970.
