In early processors, the TSC was a cycle counter, incrementing by 1 for each clock cycle (which could cause its rate to vary on processors that could change clock speed at runtime) – in later processors, it increments at a fixed rate that doesn't necessarily match the CPU clock speed.

A 2.4 GHz Pentium 4 was released on April 2, 2002, and the bus speed increased from 400 MT/s to 533 MT/s (133 MHz physical clock) for the 2.26 GHz, 2.4 GHz, and 2.53 GHz models in May, 2.66 GHz and 2.8 GHz models in August, and 3.06 GHz model in November. With Northwood, the Pentium 4 came of age.
For Pentium M processors (family [06H], models [09H, 0DH]); for Pentium 4 processors, Intel Xeon processors (family [0FH], models [00H, 01H, or 02H]); and for P6 family processors: the time-stamp counter increments with every internal processor clock cycle. The internal processor clock cycle is determined by the current core-clock to busclock ...
The replay system came about as a result of Intel's quest for ever-increasing clock speeds. These higher clock speeds necessitated very lengthy pipelines (up to 31 stages in the Prescott core). Because of this, there are six stages between the scheduler and the execution units in the Prescott core. In an attempt to maintain acceptable ...
For example, for a 1.6 GHz Pentium M, the clock frequency can be stepped down in 200 MHz decrements over the range from 1.6 to 0.6 GHz. At the same time, the voltage requirement decreases from 1.484 to 0.956 V. The result is that the power consumption theoretically goes down by a factor of 6.4.
In 2003, Intel introduced a new processor based on the P6 microarchitecture named Pentium M, which was much more power-efficient than the Mobile Pentium 4, Pentium 4 M, and Pentium III M. Dual-core versions of the Pentium M were developed under the code name Yonah and sold under the marketing names Core Duo and Pentium Dual-Core. Unlike Pentium ...
Socket 423 is a 423-pin CPU socket used by Intel's first generation of Pentium 4 processors based on the Willamette core. This socket was short-lived, as it became apparent that its electrical design proved inadequate for raising clock speeds beyond 2.0 GHz. Intel produced chips using this socket for less than a year, from November 2000 to ...
