        Alpha was a totally new, open, 64-bit RISC architecture, addressing the needs of a broad range of computer users, engineered to support multiple operating systems and designed to increase performance by a factor of 1000 over its anticipated 25-year life. The first Alpha chip was the 21064, which provided record-setting 200-MHz performance.
