Enhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville[2] and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel's microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat generation. EIST (SpeedStep III) was introduced in several Prescott 6 series in the first quarter of 2005, namely the Pentium 4 660.[1] Intel Speed Shift Technology (SST) was introduced in Intel Skylake Processor.[3]
Enhanced Intel SpeedStep Technology is sometimes abbreviated as EIST. Intel's trademark of "Intel SpeedStep" was cancelled due to the trademark being invalidated in 2012.[4]
