A few weeks back NVIDIA launched what is certainly the most anticipated graphics card series this year. The NVIDIA GeForce GTX 470 and 480 are based on NVIDIA's new Fermi architecture which is a complete overhaul of the GT200 architecture. The cards offer full support for DirectX 11 and Tesselation, as well as 3D Vision Surround for multi-monitor gaming in 3D.
The GeForce GTX 470 is based on the same Fermi core as the GTX 480 but uses a reduced shader count and less memory bus width. In the image above, you can see the disabled components of the GF100 GPU. Please note that the red rectangles can be any SM or any MC, not specifically the marked ones. This allows NVIDIA to harvest more GPUs from their production which results in a more economic end-user pricing of the product.
ASUS has sent us a final retail sample of GeForce GTX 470.
