  Overview

    The IntelŪ PentiumŪ II incorporates a dual independent bus architecture to deal with bandwidth limitations.  Composed of the L2 cache bus and the processor-to- main-memory system bus, this architecture facitilitates a simultaneous and parallel data access from both buses by the processor.  As a result, bandwidth performance is three times that of a single bus architecture.  The dual independent bus architecture is designed to support the 100MHz system bus for high-performance processing power.  Intelīs BX and GX chipsets support the Pentium II processor.

  Processor Features

  • The Pentium II utilizes features of P6 microarchitecture (namely a multi-transaction bus, Dynamic Execution performance, and Intel MMX)
  • Dual Independent Bus architecture
  • 66MHz or 100MHz system bus
  • Sing Edge Conact Cartridge packaging technology
  • 512K unified, non-blocking L2 Cache
  • 233MHz through 450MHz clock speeds

  Intel MMX Technology

    Also incorporated into the Pentium II is Intelīs MMX technology.  This technology is designed to enhance image & video compression/ decompression, as well as encryption and I/O processing used in a wide range of business media, office suites, and communication applications.  Intel created the Single Instruction Multiple Data process allowing for a single instruction to perform the same function on various pieces of data.

  Pentium II Form Factors

    There are two types of Pentium II form factor -  SECC and SECC2.  The acronym stands for Single Edge Contact Cartridge .  The SECC Pentium II is only slightly different from the SECC2 Pentium II.  Both form factors feature the 242-contact slot connector.  In the SECC2, the thermal plate is removed, allowing for better PBSRAM cooling via a direct thermal interface with the processor core.
