Well of course it won't scale exactly like that but with the 42% extra bandwidth of the 7790 and both cards having a 128bit bus the 7790 should be leading the by a bigger margin if there were any real improvements.

That may simply be AMD doubling up on the geometry engines...

It is possible that GCN 2.0 is nothing more than an improvement in terms of power consumption, clock frequencies and transistor scaling.

EDIT:
Besides, according to sweclockers, the 7790 has 12 CUs for a grand total of 768 shader ALUs.
The increase in performance from 3DMark11 is greater than the theoretical increase from 20% more shader ALUs and 7.5% higher clock speeds.

I forgot where i read that


it will probably overclock well. what the real statement was that AMD didnt want manufacturers to factory overclock them, because overclocking them will eat the profits of the 7850.

Because the PS3 GPU is faster HD 7870 equivalent.

So this looks very similar to the specs of what's going into the PS4. About 0.05TFLOPS off though, so maybe not the exact same thing.

This actually seems like a pretty decent product. It's always a fairly close competition in the sub 150 market and this looks like It could be a good competitor. Especially so if it uses a lot less power than a 7850.

So this card will compete with a 7850, or what's it's current gen AMD equivalent?

8 series is just a rehash of the 7 series though? Usually meaning just lower power consumption and/or higher clocks for OEM's. My guess is AMD is still working on GCN 2.0 and will wait for the 9 series, just as the nVidia 3-series was OEM only.
