    Description

    8086 A. A modified version of the 8086 with an 8-bit bus between the CPU and system RAM. 

    B. Had 275,000 transistors—more than 100 times the transistors included in the early 4004 chip.

    C. First to integrate a level 1 (L1) cache and a math coprocessor.

    D. Significantly helped incorporate multimedia functions and had a 64-bit bus, 16KB L1 cache and 3.3 million transistors.

    E. Considered to be the predecessor to the first true microprocessor.

    F. Features Netburst Technology.

    G. Designed for servers and high-end workstations, it is available with up to 2MB of L2 cache.

    H. The first chip that could run software written for its Intel forerunner. It has been estimated that six years after its release, it was installed in 15 million computers worldwide.

    I. The first processor capable of transferring 16-bits between the CPU and system RAM. 

    J. Standard in IBM's first line of personal computers, Altair.

    K. A server version of the Pentium IV.

    L. First to include "Katmai New Instructions" aimed at optimizing multimedia performance.

    M. Began the Single Edge Contact (SEC) cartridge format, placing the CPU into a cartridge.

    N. Introduced RISC-like features and an integrated L2 cache.
