I don't think anyone expects its new high-end to go against gm204.

And if gm200 perf is limited by 250W, with the same perf/W as gm204, it will be 35% faster.

It's true that he said AMD didn't cut their prices. Whether or not he was telling the truth is a different story.

That was only 5 years ago. He's probably referring to the 3Dmark03 kerfuffle.

I've seen this claim elsewhere, but I don't understand it: how is the Maxwell architecture closer to GCN than Kepler?

It wouldn't be the case if you still need random access to the frame buffer. Which, I think, you still need.

No. My explanation was: all known architectural changes to Maxwell are exactly the kind of thing you'd do if the...
