XFX Radeon HD 4770 review also featuring the Gainward Radeon HD 4850. The XFX Radeon HD 4770 has a 17% higher clock speed, 38% higher memory speed but 20% less Pixel Shaders compared to the Gainward Radeon HD 4850. The XFX Radeon HD 4770 does have a disadvantage which is the 128Bit Memory Interface which is half that of the Gainward Radeon HD 4850. How will this effect the performance?
