Radeon HD 5850
The younger model Radeon HD 5850, unfortunately, is somewhat cut down in functional units
It has only 1440 stream processors, the video chip operates at 725 MHz, and GDDR5 memory runs at 1050 MHz (4200 QDR). The number of raster operations blocks (ROPs) remained at the level of the older solution.
