AMD Polaris architecture – GCN 4.0

The lower Vega might be against the 1080

If the shader numbers are correct, it'll obliterate a 1080. I'd expect at least 30% faster. Some scenarios a lot more. The bigger Vega ... well ...

If one of the Vega chips is hard launched with BF1 in October, I don't think that has anything to do with NVIDIA, relative to AMD. It would have to do with HBM2 supply and price.

AMD stated there was insufficient supply and too high a price to launch HBM2 products this year.

If they're launching Vga at the beginning of Q4, that must have changed.

Not confirmed in the slightest, just a rumours that AMD will release soemthign in October to combat the 1080.

Just as Polaris were just called Polaris until they stated there are multiple chips.
If the P10 is the 480 card, then the 490 is either an even bigger Polaris, or a small Vega. So its quite possible.

I agree it makes sense that AMD have a mid-sized chip to come out before their big chip, and getting away from HBM2 will allow an earlier release and a cheaper mid-end price point.

The parts were known as Ellesmere and Baffin long before the Polaris naming came out. Along with the/a vega part being called Greenland. there were only ever 3 names known and still known till now. No fourth chip had cropped up at all in the rumour mill.

They stated that Polaris can work with GDDR and HBM, so they could do the same with Vega, and release a cut back version with GDDR5X.
At this point anything is imaginable.

Also it wouldn't make sense to release a 232mm2 chip, and after that a ~600mm2 one, and nothing in between.

So you saying there will be no cut down vega get real.

I never said that, i am talking about the designations for the dies. Polaris 11 is not a cut down 10, neither would vega 10/11 be cut down derivatives of eachother. the same as Pitcairn is not tahiti etc.

And even if they were to release a cut down Vega10/Greenland with Gddr5 etc, it would still be a vega10/greenland die.

If I go back, will I find you making the same predictions about how a Fury X will compare to a 980Ti based on shader unit counts?

Fury X does pretty well in Dx12.

The issue is having all those shaders sitting around idle... No point having them if you cant feed them :(

Yeah the new cards shouldn't need to rely on dx12 or async compute to get most of the shaders working correctly since they will have a new graphics command processor to address that issue. NVIDIA already had a better way of maximising their core usage.

I hope they still push async for us fury guys in the future. In worst case scenarios a fury x will only use 75% of its shader cores.

When can I upgrade from my r9 390?

AMD supposed to do an event by the end of the month to launch polaris, worst case scenario, you get about the same performance for like 70% less tdp, extra new features for like £200-250.
best case scenario you get 20-40% more performance on top of that for less than £300.
and i you need more performance the 1080 would give you about 50-70% more performance for ~550£ or 1070 30-40% more for about 350£

There's no way AMD are selling something with similar performance for similar money, especially after they made a song-and-dance about performance per £.

If they're selling a card in the ~£300 range, it'll be significantly faster than the 390X.

If they're only getting 390/X performance, they'll be selling it for £180-200 tops.
 
Agree, if it will be around 390(x) performance then its the successor of the 380, so should come around the price of the 380 not the 390.
