VR Zone reveals details about AMD's upcoming ATI Radeon HD 5770 and 5750 graphics cards. These two models are expected to hit the market around the Windows 7 launch timeframe for $199 and $149, respectively.
Originally rumoured to a 800 SP / 128-bit memory chip - something I doubted - Anandtech now suggests it is going to be a 14 SIMD part. Which signifies specifications of 1120 SP / 56 TMU. A cutback from the 32 ROPs in Cypress is also expected - perhaps 24 ROPs. The memory interface may end up being 192-bit. A fair increase from the previously rumoured 800 SP / 128-bit.
This means that the HD 5700 series will end up faster than the 4800 series after all, in the same price bracket. The 5750 is rumoured to be priced at $149, replacing the 4870, with the 5770 at $199, replacing the 4890.
