| 6.4 Out of 10 |  |
by techPowerUp! (Aug, 2008)When our overclocks are put in perspective to the reference clocks of the AMD HD 4850 (625/993), the margin becomes even bigger: 21% and 26.
by techPowerUp! (Jun, 2008)The chips are rated at 1.0 ns (= 1000 MHz) which is pretty much what we saw during overclocking.
