IT LOOKS LIKE we were right about Fermi being too big, too hot, and too late, Nvidia just castrated it to 448SPs. Even at that, it is a 225 watt part, slipping into the future.
The main point is from an Nvidia PDF , first found here On page 6, there are some interesting specs, 448 SPs, not 512, 1.40GHz, slower than G200's 1.476GHz, and the big '6'GB GDDR5 variant is delayed until 2H 2010. To be charitable, the last one isn't Nvidia's fault, they need 64x32GDDR5 to make it work, and that isn't coming until 2H 2010 now.

I don't know if that's completely true in my opinion, but the whitepaper comes directly from nVidia, and I just hope that the card comes with full 512sp instead of 448, so we can have healthier competition and lower prices, but every second that runs out, the Fermi card looks less impressive.
