Intel improved bit code execution performance on the Pentium II, an area in which the Pentium Pro was at a notable handicap, by adding segment register caches.
The L2 cache ran at half the processor’s clock frequency, unlike the Pentium Pro, whose off die L2 cache ran at the same frequency as the processor. The slower and cheaper L2 cache’s performance penalty was mitigated by the controllef L1 cache and architectural improvements for legacy code.
Archived from the original on Most consumer software of the day was still using at least some bit code, because of a variety of factors. The Empire Strikes Back: A fixed or removable heatsink was carried on one side, sometimes using its own fan.
These identifiers are shared with the Mendocino Celeron processors. This larger package was a compromise allowing Intel to separate the secondary cache from the processor while still keeping it on a closely coupled back-side bus. Klamath Deschutes Tonga Dixon.
This page was last edited on 16 Octoberat Inthe 0. The Pentium II Xeon was a high-end version of Deschutes core intended for use on workstations and servers. Reviews showed that the Dixon core was the fastest type of Pentium II produced.

It was cheaper to manufacture because of the separate, slower L2 cache memory. The Pentium II  brand refers to Intel ‘s sixth-generation microarchitecture ” P6 ” and x86 -compatible microprocessors introduced on May 7, Archived from the original on February 22, While Klamath features 4 cache chips and simulates dual-porting through interleaving 2x bit for a slight performance improvement on concurrent accesses, Deschutes only sports 2 cache chips and offers slightly lower L2 cache performance at the same clockspeed.
Off-package cache solved the Pentium Pro’s low yield issues, allowing Intel to introduce the Pentium II at a mainstream price level.
While this limit was practically irrelevant for the average home user at the time, it was a concern for some workstation or server users.

The improved bit performance and MMX support made it a better choice for consumer-level operating systems, such as Windows intsland multimedia applications.
The variant can be determined through the CPU part number. Retrieved September 6, The Pentium II microprocessor was largely based upon the microarchitecture of its predecessor, the Pentium Probut with some significant improvements.

Discontinued BCD oriented 4-bit General processor performance was increased while costs were cut. Late Pentium IIs also marked the switch to flip-chip based packaging with direct heatsink contact to the die, as opposed to traditional bonding.
