Into this came the early 1980's introduction of the RISC concept. At first, there was an intense debate within the industry whether the concept would actually improve performance, or if it's longer machine language programs would actually slow the execution through additional memory accesses. All such debate was ended by the mid-1980s when the first RISC-based workstations emerged; the latest Sun-3/80 running on a 20 MHz Motorola 68030 delivered about 3 MIPS, whereas the first SPARC-based Sun-4/260 with a 16 MHz SPARC delivered 10 MIPS. Hewlett-Packard, DEC and other large vendors all began moving to RISC platforms.
