The Intel Pentium M processor is based on a high performance, low power micro-architecture and includes several innovative features like an advanced branch prediction and data prefetching, Streaming SIMD Extensions 2 support, Enhanced Intel SpeedStep Technology support, Intel MMX media enhancement technology support and advanced thermal monitoring capabilities. The Intel Pentium M processor is the next step towards achieving high mobile performance at very low power. This exciting new processor supports Enhanced Intel SpeedStep technology at multiple operating points instead of two points support on existing processors. Real-time dynamic switching of the voltage and frequency between multiple performance modes is based on CPU demand. This occurs by switching the bus ratios, core operating voltage, and core processor speeds without resetting the system. Multiple Enhanced Intel SpeedStep technology operating points enable optimal performance at the lowest power.
