- INTEL FINALIZES SPECIFICATIONS FOR 80486 CHIP
-
- By Mark Brownstein:
-
- Intel Corp. has finalized its specifications for the 80486, the
- next-generation processor in its 8086/80286/80386 series,
- according to a company spokesman. The processor, targeted for
- completion in 1990, will be fabricated using low-power CMOS
- technology. It will have a 32-bit data bus and the equivalent of
- 1 million to 1.25 million transistors.
-
- By contrast, the 80286 chip has some 135,000 transistors, and the
- 80386 chip uses about 250,000 transistors, the company said. At
- a presentation given to major Businessland clients, David House,
- senior vice president of Intel and general manager of the
- company's Microcomputer Group, described what he called a "tuned
- computing engine".

- The engine will consist of a CPU, memory management, accelerators
- such as math coprocessors, and I/O controllers, including
- communications ports and high-speed graphics support. "We can
- put the CPU, cache, accelerator, and I/O on the chip and still
- have 250,000 transistors available," House said.
-
- A computer built around the 80486 chip will have the performance
- equivalent to the IBM Sierra mainframe computer, according to
- House, and will be able to execute 20 million instructions per
- second. The chip will also support the use of multiple
- processors - the addition of which will further improve the
- performance of the system. The 80486 will be compatible with the
- 8086, 80186, 80286, and 80386 chips, the spokesman stated.
-
- The chip may offer an improved human interface, which requires
- higher resolution displays, instantly available windows
- controlled through hardware, and artificial intelligence
- capability, House said. With the dropping price of memory and
- the 80486's capability to address extremely large amounts of
- memory, a high-speed, user-intuitive interface built mainly in
- hardware is conceivable, according to House.
-
- Future systems using the chip should also have hardware support
- for the leading communications and networking standards. House
- hinted that connectivity may be the proposed purpose of the
- 250,000 transistors not committed to features already described.
