Radeon HD 3450 is out
ATI's cheapest DirectX 10.1, Shader model 4.1 part will sell for $49 and its primary goal is to give Nvidia hard time with Geforce 8400GS.
ATI's chip is based on RV620, 55nanometre process and works at 600MHz and is enough to fight Geforce 8400GS performance in both games and Video.
Furthermore, if you are not happy with 600MHz clock, for $59 you can go for ATI Radeon HD 3470 that will work at 800MHz which we believe it might be the absolute record for entry level chip.
At least in some games and 3dmark 3470 is faster than Nvidia's Geforce 8500GT.
