MIPS R3000 Microprocessor

In 1988, following their revolutionary R2000, MIPS Technologies Inc. released the R3000 reduced instruction set computing (RISC) microprocessor with improved cache control. Featuring 110,000 transistors fabricated by applying 1.2 micron linewidth process techniques, the microprocessor operated at a clock speed of 20 MHz with a peak power dissipation of 4.0 watts.
