The die size arguments aren't based on Hawaii being X% smaller than GK110. It's about the chip being only 20% bigger than Tahiti at best.

Mark my words, the R9 290X will dethrone that Titan as soon as Sept 25th
*OMG OMG runs circles in pure joy*
My post actually implied quite the opposite when it comes to ROPS. Which is why I said you wouldn't want a 2800SP card. They wouldn't have the space to increase anything else. What you want is a 2560sp card with a 50% increase in ROPs. Not a 2816sp card with 32 rops...
Also GCN 2.0 is what you find in the 7790. The per core performance increase is nonexistent.
based on the same speculation. GPUdb specs are changed over and over again before launch. They're not based on anything factual unless someone validates the GPU in question with gpu-z.
