A few adjustments:
- 5870 will do close to 440 MH/s at 1 GHz gpu clock. Not many will do that without a slight voltage increase
- 5850 can do up to 400 Mh/s at 1 GHz gpu clock. That will usually require a voltage bump, which brings power consumption very near 5870 levels. At a more modest gpu overclock of 900 MHz, it will do about 350 Mh/s
- 5830 power consumption is usually nearer 5850 level, around 160-165 W
- 5770 and 6770 are the same gpu so all the numbers should be the same
- 6950 can hit 6970 MH/s numbers only with unlocked shaders. That also brings power consumption right up to 6970 level.
