I'm not even sure 4096 SP Vega will beat 1080, let alone Titan XP (talking about DX11 ofc)

I think it will, 1080 is 75% faster than RX 480? It has 2048 SP and 256 bit with normal GDDR5 memory. Vega 10 is supposed to get 4096 SP / 4096 bit / HBM2.

Vega 11 (6144 SP) is supposed to fight Titan / 1080 Ti.

The majority of AAA games this year and next still use DX11.

Nonsense all AAA games from now on will use either DX12 or Vulcan

you will still get DX11 versions but these will decrease over time and publishers wont' put as much money into optimization

Only a handful of titles are going to use DX12 for the rest of 2016. Fact.
DX11 will be around for years to come. Especially on smaller budget games. DX12 / Vulkan code is much harder to optimize than DX11.

exactly and 480 has 2304 shaders

4096/2304 = ~1.78, which means the actual perf increase of the 4096 card will be below 1.7 (or even below 1.6-1.65) aka lower than 1080 level .. and even a bit lower still if the clcoks are lower than 480 clocks as well

theoretically

You are forgetting the use of HBM2 / high bandwidth bus. RX 480 is 256 bit, and it shows in higher resolutions, as it gets slower and slower. 390X gets faster and faster than RX 480, when you up the resolution. They perform almost identical at 1080p. But 390X is 10-15% faster at 4K (not that it matters with these GPU's, but you get the picture - RX 480 is limited by bandwidth).

Vega 10 won't have to beat 1080, it needs to deliver about the same performance, for less money and it will be a good buy.

AAA games I said , there won't be any coming out just for DX11 in the near future

DX11 is discontinued now , it's redundant. I am sure some indy games will use it mind you

These threads read no differently than the OG Titan vs 290X, 780, 780Ti, 960, 970, and 980 ones.. AMD are doomed, they can't compete etc., etc.

You guys are basing AMD's future competitiveness with Nvidia against a single chip (P10), it's apples and oranges (GF vs TSMC).. Pascal is a slightly refined Maxwell, it's TSMC's process that turned out to be vastly superior than Global Foundries current one, it isn't as simple as AMD vs Nvidia.

Even Hawaii on TSMC's process would be competitive with the 1070 in raw performance (obviously not perf-per-Watt). Vega will be a superior architecture to Hawaii and Fiji, and will be using the same process as Pascal, flagship GCN 4.0 running at 1700Mhz with or without HBM2 would be a pretty beastly chip..

The RX 480 (4GB) is objectively better than the 1060 form a price to performance point of view, it's going to gain performance like all AMD cards do in the next few months, and is built with DX12/Vulkan in mind.

AMD's biggest blunder imo is once again leaving their fate to GF.. But i guess they have no choice if they want to take the fight to Intel, doesn't really have anything to do with Nvidia.

Some of the comments about AMD selling their GPU division/ wanting them to go bankrupt wouldn't be to great for Nvidia I'm afraid. Either Nvidia would be facing the full weight of AMD, or they would end up competing with far more advanced and wealthy companies. I wonder how long Nvidia could survive the likes of Samsung or Intel? My guess is not as long as AMD has managed to. thumb.gif

if you look at Polaris TDP, which is 150w and actually goes up to 160w power draw a lot, then we can gather what power draw would be if we doubled a lot of stuff. ROPs take a lot of bandwidth and tend to be power hungry as well. So if we double the front end and add in 50% more shaders then power draw would probably be right around 280w. If memory was moved to HBM2 then that could probably be cut down to about 250w. And those specs will probably be right about what Vega has.

well they're not doomed, but they arent, in fact, competing in anything higher than $250 right now
