VGA is the glint of its processing chip that is using the 40nm manufacturing so that it can accommodate more transistor in the total is 826 million, proportionate 9800GT still using the 65nm and 55nm manufacturing. Additionally Radeon HD 4770 provides GDDR5 memory faster, but unfortunately the amount of video memory (frame buffer size) have provided a new 512 MB, the process of reaching 960 GLOPs, clock speed at 750 MHz and memory clock of 800 MHz using the memory bus 128 -bit, and power consumption about 80 watts.

DirectX 10 vs. DirectX 10.1

From the diagram in the slide by AMD, there are PC games Stalker: Clear Sky as a benchmark. Setting the screen resolution at 1920x1200 with DirectX 10.1 patch the FPS (Frame per Second) almost reached 40. Slightly better than the DirectX 10 is only able to achieve 36 FPS. In addition, light and shadow effects to be more realistic rendering techniques with the min / max shadow map for the latest high-quality light touch on the surface of an object.
