AMD Star CPUs Support DDR2-1066 & SSE4A

The new Star family includes quad-core Agena, mainstream dual-core Kuma, entry dual core Rana, and single-core Spica. The new Star microarchitecture has lots of improvements includes : Hyper-Transport 3.0 (from 2GT/s to 5.2GT/s), 32B Instruction Fetch, more precise Branch Prediction and Out-of-Order Load Execution, 4 Double Precision FLOPS/Cycle, Dual 128Bit SSE calculation, and Load per Cycle. AMD is persuading JEDEC to also put DDR2-1066 as the standard, letting the faster memory can be officially and natively supported in Star. Regarding with the 48 SSE4 to be added into Intel’s next-generation 45nm products, AMD has announced last week that Star will have SSE4A, a derivative edition of SSE4 in which those Intel 64 instructions are not available. Instructions include graphic, video encoding, 3D calculation, multimedia related are all compatible in Star.
