That's not exactly how I read it.
70% uplift from process. A further 110% from the somewhat vague 'Arch+Features'. So 280% may rarely be reached, but its certainly more than the up to 170% from process alone.
Well it obviously isn't just a 1.7x perf/w improvement like you posted earlier....

Effectively, what i read there is " 1.7 from " process change " ( in yellow labeled, technology ), Arch + features change ( arch improvement, + features ).
Anyway.
Perhaps like Tonga, an OEM like Apple has reserved the initial full-CU chips.

They have 100% increase from base line there, where does that fit in with your 70% uplift from process?
The whole thing on the right doesn't' fit into the 1.7x at all. Are they constituting technology and baseline as finfet? Architecture and features on top of that? doesn't make much sense.
Anycase AMD technologies has a super scripted 1 next to it, its going to be specific applications.

@ what resolution or settings?
That 51% utilization is probably the limit of the Ashe's engine to distribute load on multiple GPUs, I bet 2 GTX 1080s would post roughly the same utilization rate.

We've already seen DX11 games where AMD managed 100% scaling, so it seems reasonable some games would do better. May be more an issue of AFR (high latency/FPS) vs SFR (low latency/moderate FPS gains). VR of course would be easy, but there are likely low utilization applications where the gains are worthwhile considering the price.
While maybe not 100% utilization, the big difference maker could be a game running a physics engine, AI, etc asynchronously. Not just async compute, but accelerating the engine at a different framerate than the rendering. Run collision every 3rd frame sort of arrangements or pathfinding in the background. They could accelerate far more complex systems that are currently used, but utilization would look strange. That sort of use would not work well with Nvidia cards asynchronously.
Seems likely considering partners are considering water cooling options beyond the dual GPU configurations. A water cooled GPU could push clocks significantly as it would help with the thermal density issues. Consider a Fury running 50C as opposed to air cooled cards ~70C. The current 480 card they've shown lines up much better with a cut down Polaris 10 version, so there is room for an improved version.
I've wondered the same thing. Normally the xx5 series was already the off-year refresh. The other option may be the full chip being 490 series with Vega being a Fury/Rage tier with a big chip and maybe professional for the 2nd variant. A small Vega MCM, considering HBM2 and an interposer already, could be a possibility.
100% baseline + 70% uplift from 'technology' = 1.7x performance/w with finFET
So you don't understand percentages and are somehow making claims that they are lying?
its not a lie (its confusion the way they broke it down), its specific applications hence the super script. What did nV lie about 10x the performance? No, its specific applications.
OMG... they are stating upto 2.8x perf/w increase due to 14FinFet, Polaris architecture and features.
Well, not much terrible that the x1900XT- x1950XTX
yes and it will in specific applications, that is what is noted on the slide, AMDtechnologies which I just linked you to what those were.
What happened to the 60% decrease in power usage with FinFets, that is the same as 2.0 perf/watt increase. Its no longer that.

Well, I'm and idiot. Then again so is AMD.
This was supposed to be the year they made a turnaround. The stock market has been betting on it. How the fuck is this a turnaround? Dual GPU for a low end card, not a mid range, but a low end thing? It's mind blowingly stupid for any company, especially one that was supposed to be on the right track.
