RV870 single-core, R870 dual-core, R800 quad-core?

So they are not going to go directly to 40nm? Oh, you are right, ideal scaling would be 52% (40/55)^2 or 66 % (45/55)^2. So, expecting at least ~60 % or ~73 % smaller chips. Yet another sleepless night makes this thinking impossible.

So, if they are pad limited then RV790 should be at least 1280 shaders, even if they are going to 45nm first. If RV870 was 40 nm, then 1500-1600+ shaders should be very well possible.
