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.
The increased clock rate is limited by the processor's power, current, and thermal limits, the number of cores currently in use, and the maximum frequency of the active cores. [ 1 ] Turbo-Boost-enabled processors are the Core i3 , Core i5 , Core i7 , Core i9 and Xeon series [ 1 ] manufactured since 2008, more particularly, those based on the ...

Arrandale is a later mobile processor but opens a new line of mid-range dual-core processors with integrated graphics. At the time of its release at the Intel Developer Forum on September 23, 2009, Clarksfield processors were significantly faster than any other laptop processor, [ 2 ] including the Core 2 Extreme QX9300.
Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...
An Intel Pentium Mobile, clocked at 300 MHz (1998). A mobile processor is a microprocessor designed for mobile devices such as laptops and cell phones.. A CPU chip is designed for portable computers to run fanless, under 10 to 15W, which is cool enough without a fan. [1]
