The nVidia internal code name for the GF110 was actually GF100b. The GF110 is really nothing more than a base layer respin of the GF100. Nothing changed except fixing the leaking areas.



I agree that it would be a waste of money if they just completely dumped the Fermi architecture. I don't think they can maintain that arch for long unless the professional side can continue support the gaming side. Without the professional sales, nVidia is in the red for the year AFAIK.
Don't forget that gf100 and gf104 are different themselves.

The really odd thing is that you can still buy gtx480. I know it is only a cut down failed gpu die.

Why and how did they make so many of them?

There weren't that many made. The high end never sells in abundance so its easy to have leftovers. Now they are overshadowed by nVidia's newer chips, therefore undesirable. There was also probably stock leftover, intended for the professional side that now is used for video cards instead.

They even told that Ati was in a hurry with 5xxx because they were afraid of a fermi launch. I will try to find the article it came out at summer 2009.

If you have a die 30% bigger you need more than 30% more performance because it costs more than 30% to produce if you want the same profits. Remember bigger chips = lower yields. That is why fermi needed sth like 40% more performance just to be as good chip as cypress (from market perspective always).

Not only "a hurried launch", but with "non-native DirectX 11 support"...
AMD's reply was "How many DirectX 11 GPUs were shipped from us in 2 years?"

Oh, how I love the satire...

That'd be interesting as that'd mean with proper BIOS/drivers you get higher DP flops for GPGPU. Anyone wants to give that a try?

Wouldn't that in principle be true for all of them?

They use the exact same die, but I don't know if they choose the DP rate in software, firmware or by actual hardware modification.
