But yeah, if you're disappointed with nearly 2x perf. increase over the last gen, it's your thing afterall.

Let's wait for R900 and new(?) ľArch, hopefully there will be changes in the efficiency.
Again I bring up RV770. The only known feature about that chip (just before and during launch) was its 2.5x increase in ALU count. Impressive in its own right, however it brought more than a 2.5x performance increase over R600 and RV670.

Also I was comparing the jump from R700 (2xRV770) not 2xRV790. In this light (2xRV790), Cypress looks even more unimpressive, with an average 1.6x increase over RV790 (they share the same core clocks, so it's quite fair to compare the two architectures).

Somehow, a 40% theoretical performance advantage was lost during the 100% increase in specifications count.

As I said in my original drivers, it could just be the beta drivers not showing Cypress' fullest potential. But given that R600, RV770 and Cypress share the same underlying base architecture, I don't think there's too much to be squeezed out of new drivers. Still, I could be surprised...
