On 28nm? Yes.

Even if we assume a generous 10%, that's still 15% off from the official figure. Like I said, my main point was simply shader count and clockspeed doesn't tell the full story about shader efficiency, if the Kepler to Maxwell example is indicative of anything.
I see what you mean.

If what blue1512 found, is true, like if it can get 1700mhz oc even at 200w I think it will be tremendous. Smaller chip at lower clock beating bigger chips with higher clocks(gtx1070)

Well all we have to go on so far is 3dmark leaks. I wouldn't call that conclusive evidence of no improvement.

Games can tell a different story.

The big celebration they have just had could be its taping out - if that's right then its definitely taped out on 14nm vs 7nm due to the tech available now. However they will want to respin in a few times to tune it hence delay.

AMD had not said that, but Samsung is saying they'll have 7nm out by end of 2017, assuming they can hit their goal, it'll coincide with AMD's planned launch of Vega. GF is using Samsung tech, so it makes sense that the 4xx generation won't have a big die, they are probably saving money this gen and waiting for the next gen on 7nm.

What did blue find?

1680mhz clocks for a split second before power limiters kicked in , i think it was dota 2 he was playing.

I have been touting the same horn ever since AMDs declaration to conquer the mainstream markets a couple months back. R9 390s have been available for $250 or less for months now. Repackaging that performance into a smaller die to save costs and then delivering it at the same price isn't exactly groundbreaking.

250$ is still not the typical price for a 390.
Basically you are comparing the best offers and prices you can find for a 390 with 480's MSRP.
The thing is if we apply logic the 480 starts at 200-230$ which means that in time this price should decrease and after a few months you should find the 480 whit offers below 200$.
At the end of it's life cycle you will most likely be able to buy a 480 for 170-180$ maybe even less.

Source? That's incredibly interesting if true.
