AMD has introduced its latest processor refresh, a quad-core Opteron processor using a new 45-nanometer manufacturing process. The "Shanghai" chips improve performance over last year's "Barcelona" model, built on a 65-nanometer process, by running at a higher clock frequency. Besides a speed bump, Shanghai chips use a new cache backup to save power: individual cores can dump their L1 and L2 caches into the shared six megabytes of L3 cache and power-down completely, restoring them later when needed. Memory performance is upgraded with a bandwidth boost from DDR2-667 to DDR2-800. The chips are pin-compatible with Barcelona models, and can be directly swapped out for a quick upgrade. Shanghai is aimed at servers, with AMD poised to release a desktop-destined 45-nanometer chip in 2009.
