So according to this is FERMI really a GF100 card now? Not 3xx?

Yeah which was based on the whole G70->G80->G90/92->G100 concept.

At this point most of the chips names have lost all meaning anyways with GXXb versions and the rebrands etc. Few people even know it's the G200, most people still call it the GT200 despite G200 being right on the die itself. :heink:
