AMD is said to be working on a cheaper Radeon HD 4800 series graphics card. FUD Zilla says we can expect a RV770 LE GPU in October:
It is a crippled version of the Radeon 4850 and it should end up way slower and cheaper than its stronger brother, while at the same time it aims to make Nvidia's life even tougher.
The memory bandwidth will be cut to 192 bits while the original RV770 has a 256-bit memory interface and both clocks and Shaders will be slower compared to RV770PRO. At the same time RV770LE will end up significantly slower than RV770PRO but this is something that doesn't surprise us.
