Cyrix Cx486SLC Microprocessor

The Cyrix Cx486SLC was Cyrix's first CPU offering, released after years of selling coprocessors that competed with Intel's units and offered better performance at a comparable or lower price.

CPU manufacturer Cyrix began in 1988 as a specialist supplier of high-performance maths co-processors for 286 and 386 systems. ... This CPU uses numerous pins to connect to the motherboard. ... A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). ...

The 486SLC was intended as an entry-level chip to compete with the Intel 386SX and 486SX. Texas Instruments, who manufactured the 486SLC for Cyrix, also released its own version of the chip, the TI486SXLC which featured 8kB internal cache vs 1kB in the original Cyrix design. The similarly named IBM 486SLC chips were not related to the Cyrix design, however. Texas Instruments (NYSE: TXN), better known in the electronics industry as TI, is a company based in Dallas, Texas, renowned for developing and commercializing semiconductor and computer technology. ...

Introduced in May 1992, like the later and more famous Cyrix Cx5x86 it was a hybrid CPU, incorporating features of a new CPU (in this case the Intel 80486) while plugging into its predecessor's socket. It ran at speeds of 25, 33, and 40 MHz, although it had difficulty running reliably at 40 MHz using some operating systems. 1992 is a leap year starting on Wednesday of the Gregorian calendar. ... Released in August 1995, four months before the more famous Cyrix 6x86, the Cyrix Cx5x86 was the fastest CPU ever produced for Socket 3 computer systems. ... An Intel i486 Microprocessor The Intel i486 (also called 486 or 80486) is a range of Intel CISC microprocessors which is part of the Intel x86 family of processors. ...

The 486SLC can be described as a 386SX with the 486 instruction set and 1K of onboard L1 cache added. Unfortunately it inherited the 386SX's 16-bit bus and with it the limitation of 16 MB of RAM. Like the 386 and 486SX, it had no on-board math coprocessor, but unlike the 486SX, it could make use of an Intel 387sx or compatible coprocessor. Due to the limitations of the 386SX's bus and its smaller L1 cache, its performance could not compete with the 486SX. Diagram of a CPU memory cache A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. ... A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). ...

The 486SLC was primarily used in very inexpensive low-end motherboards and PC clones. Because of its low power consumption, it also saw use in laptops. A motherboard, also known as main board, logic board or system board, and sometimes abbreviated as mobo, is the central or primary circuit board making up a complex electronic system, such as a computer. ...
