The HD 4750 has similar specifications to the HD 4770. It even sports GDDR5 memory. The RV740 core runs at 730 MHz, and its memory at 800 MHz (3200 MHz effective). While the memory clock speed is identical to that of the HD 4770, the core is clocked slightly lower. Overall, the card won't have as much overclocking headroom as the HD 4770, because it will not draw power from a 6-pin power connector. The design ensures existing low-performing raw materials are utilized more effectively.
