Cyrix
Cyrix Corporation was a microprocessor developer that was founded in 1988 in Richardson, Texas as a specialist supplier of high-performance math coprocessors for 286 and 386 microprocessors. The company was founded by former Texas Instruments staff members and had a long but troubled relationship...

Released in August 1995, four months before the more famous Cyrix 6x86, the Cyrix 5x86 was one of the fastest CPUs ever produced for Socket 3 computer systems...
CPU
Central processing unit
The central processing unit is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in...

386SLC
The 386SLC was an Intel-licensed version of the 386SX , developed and manufactured by IBM in 1991. It included power-management capabilities and an 8KB internal cache, which enabled it to yield comparable performance to 386DX processors of the same clock speed, which were considerably more expensive...
and IBM 486SLC, were based on modified Intel designs.

- iDX4WB pinout, 168 pins
- Socket 3Socket 3Socket 3 was one of the series of CPU Sockets into which various x86 microprocessors were inserted. It was sometimes found alongside a secondary socket designed for a math coprocessor chip, in this case the 487. Socket 3 resulted from Intel's creation of lower voltage microprocessors...

- 16 kilobyteKilobyteThe kilobyte is a multiple of the unit byte for digital information. Although the prefix kilo- means 1000, the term kilobyte and symbol KB have historically been used to refer to either 1024 bytes or 1000 bytes, dependent upon context, in the fields of computer science and information...
