Radeon HD 4750
The Radeon HD 4750 is based on the RV740 chip. That will endow the video card with a similar number of functional blocks with the Radeon HD 4770. The novelty will be equipped with GDDR-5 memory and received a 128-bit bus. The operating frequencies are slightly reduced compared to those of the Radeon HD 4770, to be more precise, only the frequency of the graphics core. Instead of 750 MHz, the value is 730 MHz. Memory runs at 900 MHz
