Review of Overclocked Radeon HD 4770 |

AMD launched Radeon HD 4770 (RV740) on April 28th which is the first GPU built on 40nm manufacturing process. As we mentioned, Radeon HD 4770 is coming with 640 stream processors and core/memory clock of 750/800MHz. AMD has slashed the memory interface to 128-bit, while adopts GDDR5 memory to make up the bandwidth loss. Actually, the reduction of memory interface is good for PCB wiring, and helps to reduce the die size.
