Today we will be covering the ATI top card in the form of the 4870. The 4870 is based on the long awaited RV770 from AMD. The RV770 core was manufacturer from the 55 nanometer technology. This whole technology is what gave us DirectX 10.1, Shader 4.1 and PCIe 2.0 support. The most impressive feature that we see in the new 4870 GPU is the GDDR5 which is clocked at 900MHz in this new AMD card.
