Re: NVIDIA's 2012 Kepler lineup revealed (possibly)
That has only been true for GTX400 to GTX500 as it was only a refresh.
But the GTX470 was quite a bit more powerful than a GTX275.
Kepler seems to be about 1.5~2.0 Fermi at each level (GK110 ~ 2x GF110, GK104 ~ 1.5xGF114...) so huge perf boosts should be expected.
We'll see. Table is still missing the GK107, but that should be mostly laptop.
As the universe is curved, there cannot be a straight answer...
