AMD Polaris architecture – GCN 4.0

If I went for Polaris 10 and say dropped £300 on it and later when the full fat cards come out at (a guess of) £500. What do the seasoned upgraders out there think the cost to upgrade to Vega would be, £300?
 
Hard to tell depends if Vega slots above Polaris price point or pushing Polaris price point down a bit as we don't know hardly any thing about Polaris never mind Vega.

Amd will not want to leave a gap between Polaris and Vega for Nvidia to exploit if they know what is good for them.
 
So your expecting a chip that is considerably smaller, uses considerably less power, has a bus half the size, than the 390/X to perform half as fast again.

As that is what it will need to do to match a 1070. ( the TitanX is about one and half times faster than a 970/980 ergo 390/X and we were told the 1070 beats the TitanX)

The new node shrink has shown to offer good performance, as seen by the NVidia launch, but I think you are asking a just a bit too much.

Go re-read my post, I absolutely did not say P10 would be 50% (half as fast again) faster than 390X, I clearly said it needs to be 30% faster than 390 (non X) to roughly equal 980Ti/Fury X. My whole premise is based on price/perf compared to 1070. The link I gave from TPU shows R9 390 at ~30% slower than 980Ti/Fury X across most resolutions.

AMD have stated P10 is a replacement for R9 390/X and as such a lot of people erroneously assume it means it will have the same performance. As is the norm the direct replacements on each tier is usually ~25%+ faster. That IMHO will put Polaris 10 at around reference 980Ti/Fury X performance.
 
If DX11 is going to continue on AMD have no choice but to adopt the same system Nvidia use for getting round the Drawcalls issue.

DX11 is a lot like Moore's Law, even before here and now you can pile on as many shaders as you can cram in, if you can't get around the bootleneck the more shaders you stuff onto your GPU the more shaders sit idle doing nothing and your performance remains the same, the only thing that you see increase is power-consumption. Fiji's problem, even to some extent Hawaii's problem....

Now take my GPU, it looks like a GTX 770 on steroids, in shader terms that's exactly what it is, there main difference is Maxwell vs Kepler has a completely different front end, Maxwell is far more able to make use of all the shaders it has all the time, much more than Kepler is.
So what you end up with is a GPU about the size of a GTX 770, with about the same number of shaders and with about the same power consumption, and yet massively faster.

Its not so much about who can make the most powerful GPU anymore, its about balancing raw power with how much of that you can actually use.
With that AMD have hit the wall With Hawaii, never mind Fiji.
Polaris will have far better DX11 Drawcalls because AMD know if it doesn't they have no chance of moving performance forward. because DX12 ain't taking over yet.

If I understand correctly Vega will be a much bigger chip and consequently more expensive. If it also goes toe to toe with Nvidia's high end I'd expect the price to be similar. Of course as you say we know very few real facts at the moment. The people paid to decide on the business strategy certainly do earn their money in this industry :)
 
Is there actually any chance of seeing anything from AMD before 1080/1070 launch? I mean i'd be willing to wait if I could see something concrete from AMD worth waiting for.

"Nothing" won't cut it for me, for all I know it could mean no Polaris until Q4 or something as silly.

Has there not even been rumours of any press events for Polaris announcements?
 
They need to, before launch but they will leave it a few day before I hope, they got that new women from Nvidia for PR we see how she will do we can all shout at her if they screw up.
 
Even the 290/390 has a DX11 CPU batching problem, i know that for a fact as i went from a 290 to a GTX 970 and given that i develop my own games i can see whats going on in the background.

The truth of the matter is Maxwell is far more efficient at batching, the result is Maxwell can push about 70% more drawcalls in DX11 than AMD can.

The reason why its far more pronounced with Fiji than it is with Hawaii-XT at 1080P is because Fiji is a massively more powerful architecture.
This is why you often see a Fiji GPU only a little faster than a Hawaii-XT, at 1080P, at higher resolution like 4K where the power of the GPU is more important than Drawcalls Fiji comes into its own.

As a GPU its actually more powerful than a GTX 980TI, Fiji's problem is the 980TI is able to use more of its rendering power than Fiji can, at least at 1080P in DX11.

Now, the head of the AMD Radeon Group, Raja Koduri, has actually admitted this problem with thier GPU's, and has said they have completely rebuilt the front end of their GPU's for Polaris to fix this problem.

;)
 
I'd also like to see AMD revisit the stock air cooler and refine it to something like the Titan cooler. As it stands, they're miles behind in this regard.

[Edit] Also can we have another card with the aesthetic of the 5970 Vapor-X? That card looks the absolute mutts nuts.

Is it possible that Vega is not just ONE chip? Polaris is two different GPU's. Could Vega also be?
 
Still no news from AMD yet?

It’s not a good time to release details to the press at the moment. The thing is most of the tech press is all excited about the all-expenses paid for press event Nvidia laid on for them so they could tell them that after $17 billion of R&D investment and a 75% shrink in the process they have managed to conjure up a whopping 20% increase in performance.

Naturally we all very excited about this 20% so I would expect AMD to wait until the end of the week or maybe early next week to release some news about Polaris. If they release a statement today it will get lost in noise and won’t have the same impact as a statement released on a slow news day.
