AMD New Polaris GPU Revisions w/50% Better Perf/Watt (NX delay reason?)

I can see AMD launching xx5 revisions as they showed in that slide explaining the naming of the new cards. What I don't believe is the 50% improvement claimed by those sites.

Up to 15, maybe 20% by next year as the process gets more mature and refined could be, but a 50% improvement in only 4 months since the 480 launched? No way.

fwiw http://www.anandtech.com/show/10710/amd-announces-embedded-radeon-e9260-e9550 

So AMD has the products cited in the wccftech article, so what?

Looking at the anandtech article you linked, you can see that those new products replace another two, produced in 28nm and with an older and less efficient architecture that don't consume that much more power and, in fact, use a lot less power than their desktop counterparts.

For example, taken from that article, the E8950 that is replaced by the newer E9550 is based on the Tonga architecture, features 2048 shaders and is rated at 95W. The desktop version would be the R9 380X that is also based on Tonga and has 2048 shaders, and guess what, it's rated at 190W. And that's despite being a 4GB card compared to the 8GB of the embbeded product!

Summary: using embbeded products to extrapolate the performance or power consumption of the desktop versions doesn't work.
