Wintel

The world's largest manufacturer of computer chips. Although it has been challenged in recent years by newcomers AMD and Cyrix, Intel still dominates the market for PC microprocessors. Nearly all PCs are based on Intel's x86 architecture.

Intel was founded in 1968 by Bob Noyce and Gordon Moore. Strategically, it is closely allied with Microsoft because the Windows 3.x and 95 operating systems are designed for x86 microprocessors. The popularity of Windows creates a demand for Intel or Intel-compatible microprocessors. Many people refer to this alliance as Wintel (short for Windows-Intel).

Notes
80861978 0.516 165, 8, and 10
80881979 0.516 85 and 8 Used in the original IBM PC and PC/XT.
802861982 1.516 168, 10, and 12 Supports virtual memory and an address space of 16MB (megabytes); is 5 to 20 times faster than the 8086
80386DX1985 1032 3216, 20, 25, and 33 Built-in multitasking and virtual memory, has an address space of 4GB; is 2 to 4 times faster than the 80286
80386SX1988 2.532 1616, 20, 25, and 33 Compatible with both the 80286 and the 80386
80386SL1990 532 3220 and 25 Same architecture as the 80386DX, but with added power management features; popular in portable computers that rely on a battery for power.
80486DX1989 3032 3225, 33 and 50 Similar to the 386 but much faster; uses a built-in memory cache to avoid wait states and includes a numeric coprocessor; uses pipelining techniques.
80486SX1991 2032 3216, 20, 25, and 33 An inexpensive variety of the 80486DX that runs at low speeds and lacks a numeric coprocessor.
80486SL1992 2032 3220, 25, and 33 Based on 80486DX architecture, with power management features for battery-operated computers.
80486DX2 and OverDrive 199250 3232 50 and 66Same architecture as the 80486DX, but with the internal clock speed doubled.
486DX41994 7032 3275 and 100 Same architecture as the 80486DX, but with the internal clock rate tripled.
Pentium1993 12532 6460, 66, 75, 100, 120, 133, 150, 166 and 200 Although basically a CISC architecture, the Pentium chip includes many RISC features, such as pipelining and superscaling; contains more than 3 million transistors.
Pentium OverDrive1995 32 6460, 66, and 100 A Pentium chip that can be installed in a 486-based computer that has an OverDrive socket.
Pentium Pro1995 32 64150, 166, 180 and 200 More than 5 million transistors.
Pentium with MMX1997 32 64166 and 200 Pentium processor with the MMX chip for faster multimedia processing
MMX Overdrive1997 32 64MMX upgrade for Pentium processors.
Pentium II1997 32 64233, 266, 300, 333,350 and 400 Uses DIB and SEC packaging; supports AGP
