Overview
The Cyrix M1 architecture is a superscalar, superpipelined x86 processor architecture operating at very high clock rates. The architecture's sophisticated dependency- and conflict-reduction schemes are implemented in hardware, allowing it to deliver performance increases of roughly 2.5 times that of the 486 architecture operating at an identical clock rate, and a gain of 30%50% over the Pentium at an identical clock rate when running today's applications. This architectural advantage, coupled with the core clock rates of 100 MHz and better, yield up to five times the performance of a 486-50, and up to two times that of a current Pentium processor. The M1 architecture provides more than 12 times the performance of a typical RISC-based architecture operating in "compatibility" mode, the mode required for the RISC architecture to run existing x86 software. |
