No, unless you are using AA, the max for GF110 is 24.83 Gigapixels/sec. Tahiti is 29.6 GP/sec by the same math.

So who's more efficient and does this count as supporting evidence enough?
No. It doesn't.

The numbers are 9.75 for Fermi and 13.3 for Tahiti. Why isn't Tahiti getting 29.6? Because the test is bandwidth limited. Now, the 7970 has 37% more bandwidth than the 580, so if the test is bandwidth limited we should expect the 7970 to perform 37% better than the 580. 13.3 / 9.75 = 1.364. SHOCKING. The 7970's advantage over the 580 is exactly equal to its bandwidth advantage in a bandwidth limited test... imagine that.

This is the third time I have explained the result, and I really don't think I can make it any simpler or more clear. If at this point you can not understand that the test is completely bandwidth limited, then I must conclude you are either 1) intentionally trolling and not worth having a conversation with or 2) genuinely intellectually incapable of understanding and not worth having a conversation with.
