The Pentium II[2] brand refers to Intel's sixth-generation microarchitecture ("P6") and x86-compatible microprocessors introduced on May 7, 1997. Containing 7.5 million transistors (27.4 million in the case of the mobile Dixon with 256 KB on-die L2 cache), the Pentium II featured an improved version of the first P6-generation core of the Pentium Pro, which contained 5.5 million transistors. However, its L2 cache subsystem was a downgrade when compared to the Pentium Pros. It is a single-core microprocessor.
In 1998, Intel stratified the Pentium II family by releasing the Pentium II-based Celeron line of processors for low-end computers and the Pentium II Xeon line for servers and workstations. The Celeron was characterized by a reduced or omitted (in some cases present but disabled) on-die full-speed L2 cache and a 66 MT/s FSB. The Xeon was characterized by a range of full-speed L2 cache (from 512 KB to 2048 KB), a 100 MT/s FSB, a different physical interface (Slot 2), and support for symmetric multiprocessing.
In February 1999, the Pentium II was replaced by the nearly identical Pentium III, which only added the then-new SSE instruction set. However, the older family would continue to be produced until June 2001 for desktop units,[3] September 2001 for mobile units,[4] and the end of 2003 for embedded devices.[1]
