Yeah I got that, however while that might generally have been true, in order to make more accurate estimations you need more info to back it up, which is where all this stuff about rejected GPUs for teslas, GK104 -> GK104 etc. stuff comes in.

And before you break your fingers typing back that the 660Ti and 680 are both GK104, remember that not all GK104's can be made into 680's (due to binning for clock speeds) so there is a performance difference between the two
. That is why the comparison is flawed. We don't know how high Nvidia could have binned GF104 if they had tried to make it into the GTX 580 but if they had then the comparison would be valid...
Performs as a high end card relative to what? If you're going to say AMD, it makes no difference since the discussion was strictly about Nvidia. And even if it did, that would mean that lower end 8800GTS 320MB cards which cost around 300 bucks were high end in NV's lineup just because AMD's 2900XT sucked, bad.
When trying to compare GK104 -> GK110 transition to GF104 -> GF110 there is absolutely 0 reason take into account AMD's GPUs unless prices are a factor.
You also have to remember that there were more than one 460, and when they moved to 560s, there were even more. Comparing a fully fledged mid range chip (460) to a gimped mid range chip (660Ti) makes no sense. That's not how the chips are positioned when supposed costs are taken into account.
I don't know how many times I have to spew this in GK110 threads but the "mid range chip" stuff has nothing to do with:
- Product names
- Competing products
What it is all about is: cost of manufacturing, die sizes (cost), the relative place of the GPU in NV's line of GPUs (internal), features (such as proper dp perf) and so on. Please do not confuse the two.
