DX12 is not the standard, DX11 will be here for many years. Adding a 2nd 480, 470 or 460 in 2 years would make no sense, since a single mid-end card at that time, would outperform it anyway. VRAM will probably be too low too (unless 480/8GB).
The thing is I am only planning on getting a budget GPU from the very start, but I also like to at least keep my option open, for ex. in-case GPU performance are stagnant >2yrs like we had on 28nm, I can add another in later on without getting stuck on same performance I had. I put no faith in TSMC able to deliver 10nm on time.

So it is either Radeon or Nvidia at these price range, but Radeon have 1 advantage. So I opt for this one.

Infact I am actually leaning towards a RX470 if it is rumored 32CU @ $149. Thats gonna be better performance/price than RX480

Yes, why not have an option to add a cheap 2nd card in CF down the road? NV is acting like apple, that's another problem.

that is only if GPU are stagnant like we had in 28nm, I doubt we get a huge performance bump on the very same 14/16nm process in 2yrs. Those 1080/1070, it is going to stay high end for a couple of years.

I don't think so. 1080 and 1070 have their performance because of the massive clock speeds. I'm assuming nVidia are going to do the same with the next gen cards but add a massive overhaul to the architecture. Pascal is basically a stop gap. I'm rooting for AMD, but it seems like they are going to get blown away unless they can rework GCN(since they seem all in on the arch) because 1.3-1.4Ghz on the core isn't going to cut it if the other guy can hit 2Ghz+. Brute force is always going to win out.

They are competitive with their midrange card in DX12 & Vulcan

I'd imagine their high end chip when they release it will also be competitive at the high end

A 480 with double the ROP's , HBM and higher clock speed would be quite the card ...

But can they do it without massive power usage and have decent clock speeds? It seems unlikely at this point. AMD has been competitive for years, which is why I usually buy them(and buy nVidia cards used). They are only really competitive in DX12 and Vulkan because nVidia has shown no real interest in it yet because it's unnecessary(from a hardware perspective). nVidia cards run the OpenGL version of Doom just fine.

I don't see the benefit to HBM with current cards. They don't seem bandwidth limited and I think the arch needs to be designed with it in mind. Would just raise prices for no benefit other than a feature, see Fury.

Why would it seem unlikely at this point ?

you are also missing the point of DX12 / Vulcan on AMD. They have focussed on this as it's the future. Just about all AAA games coming out from now will use DX12 , this is why AMD have concentrated on that. Better for future proof

That not really true. A few games will get DX12 support, but they are still built around DX11. Battlefield 1 to name one. Alpha is DX11.
The majority of AAA games this year and next still use DX11.

Exactly. This recent launch of GPUsfrom both teams has really shown just how far ahead Nvidia is.

Like Intel vs AMD on the CPU end, they have every aspect covered. Performance, efficiency, and price to performance.

Yes price to performance is absolutely there when you factor in what's necessary to run FX cores to respectable clocks.

This RX 480 was a winner till Nvidia dropped their 1060 to the consumer at $250.

yes, but with a considerably higher power usage and bigger die (480 vs 1060)

so Pascal enthusiast top-end has more "room" to add more GPU power than Polaris/GCN4


even a literally 2x faster than 480 card still wont quite reach Titan XP level (most likely) and making 480 2 times faster will require more than x2 shader count (scaling is never 1:1)


and HBM2 isnt really an advantage since Nvidia will likely have its own HBM2 card/cards (either 1080Ti or Volta) to compete with HBM2 Vega
