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.

Thanks to the advanced 40nm technology, Radeon HD 4770 does pretty well in power consumption management. According to our benchmark, HD 4770 also shows great overclocking potential, and we recommend you to set the clocks as 850/1000MHz when overclocking.

Radeon HD 4770 was only behind HD 4850 by 5.66% according to our test, so what would happen if HD 4770 is overclocked?
