Radeon HD 7770 2GB GHz Edition Review

Radeon HD 7770 2GB GHz Edition is a variant of the Radeon HD 7770 GHz Edition aka just Radeon HD 7770.
The only difference between this version and the original is the increase in the video memory that was doubled from 1GB to 2GB.
It's proved that extra memory for this GPU does not yield extra performance. Therefore, this GPU's performance is exactly like the standards.

I do think it won't bring any improvements for res (1680x1200). But I wonder if the extra Gb won't allow to have similar performance on higher resolutions (1920x1080)?

More VRAM comes in handy for larger resolution so it improves performance, but 2GB fits more the high-end GPUs that do perform well on Full HD, and it won't benefit much the middle class GPUs

yes, the bitrate and bandwidth eventually decides how much the memory will be in need. Therefore, how much it will be fully used.

7750 uses 55w max power and 7770 uses 85w max power ! if your psu have power connector then 7770 is bit better and if you dont have power connector then 7750 would run just fine :) your motherboard will support this gpu :)
