Evo nesto za pocetak:
http://www.techpowerup.com/reviews/ATI/HD_4770/
Odlican test, odlicna karta ali power management i nije bas extra:
Even though ATI has implemented a 2D/3D clock switching model, the power consumption in idle is still quite high. One reason for that is that only the core frequency is reduced, while memory keeps running at full speed for the whole time. During testing I noticed that any memory frequency change will make the screen display flicker, which is probably the reason why AMD chose not to allow dynamic memory clock changes. I am surprised that AMD has not fixed this problem in their second GDDR5-capable GPU.
Ovo sa GDDR5 mogu da potvrdim jer sam pokusavao na mojoj Gainward 4850 GS GLH DDR5 da editujem bios. Maksimalno sto sam uspeo da spustim memoriju je na 700 MHz sve ispod toga rezultuje nestabilnoscu slike. Krajnji rezultata idle 300/700, UVD 500/700, full 700/900, (nista nije overklokovano jer nemam potrebu za tim) fan 25% (necujan) do 60c nakon toga linearan rast (105c-100% vent).
