Gigabyte Radeon HD 4770 review also featuring the Sapphire Radeon HD 4830. The Gigabyte Radeon HD 4770 has a 24% higher clock speed, 44% higher memory speed and the same 640 Pixel Shaders as the Sapphire Radeon HD 4830. The Gigabyte Radeon HD 4770 does have a disadvantage which is the 128Bit Memory Interface which is half that of the Sapphire Radeon HD 4830. Will the advantages outweigh the disadvantages?
