If not mission-critical stability, GeForce BETA drivers do tend to be great speculation starters. The driver information file packs entries for existing supported GPUs, as well as some future GPUs. GeForce 285 BETA drivers seem to have contained entries for two such future GPUs, marked "NVIDIA GeForce 610M" and "NVIDIA GeForce GT 630M", with identifications of NVIDIA_DEV.1058.01 and NVIDIA_DEV.0DE9.01, respectively.

These new "discoveries" more or less fall in line with an earlier report of NVIDIA having taped out its first GeForce Kepler family GPU, the GK107. It is becoming clear that NVIDIA has charted out a bottom-up course for its next GPU family, to play safe with the new 28 nm fabrication processes at TSMC, that of beginning with the simplest GPUs, and then scaling them up till the highest-performing part is perfected.
