Yeah, but that 25% difference was at stock speeds. 750 is 20% higher than 625, so are we to assume that at stock speeds, the GDDR5 only gives the 4870 a 5% advantage, clock per clock? That's a pretty crappy value if so and would explain the BIOS lock. I'm curious to see if that gap widens with higher core speeds.
