AMD has launched the Radeon 7970, the first graphics card based on its next-gen Southern Islands architecture, which relies on 28nm chip manufacturing technology from TSM. Reviews show the 7970 to have a healthy performance edge over competing high-end cards featuring only a single graphics processor. Archrival Nvidia's (NASDAQ:NVDA) first 28nm graphics chips might not arrive until March.
