The rumour mill has been running wild lately about the Fermi but this seems to be semi-official so here we go:GeForce GTX 380 and GeForce GTX 360 are the leaked official names for the codename Fermi product
and here are the specs below, followed by some leaked benchmarks. Too late for Christmas?
Even though it might be adding to the rumour mill, these numbers look about right.
