What year did the 486 come out?
What year did the 486 come out?
1989
Introduced in 1989, it was the successor to the 386 and the first chip in the line to include a built-in math coprocessor. Providing acceptable performance for DOS, it was bare minimum for Windows. Later versions of the chip doubled and tripled internal speeds (see DX2 and DX4).
How many chips did the Intel 486 have?
486 introduced a number of enhancements to 386 including a new level 1 cache, better IPC performance, and an integrated FPU. The 486 became the first x86 chip family to exceed one million transistors.
What is a 486 computer?
A computer processor developed by Intel as an upgrade to the 386 processor series and commonly referred to as the 486 or i486. The 80486 has 8 k of memory cache built into the processor with 32-bit data bus architecture and was available in clock rates ranging from 20 MHz to 33 MHz.
What is i486 architecture?
The revolution in desktop computing has made Intel’s x86 architecture a de facto standard in the PC industry. The i386/i486 is not only an architectural upgrade of its predecessor, the 8086/88, it also incorporates multitasking, paging, hardware protection, debugging support, and a 32-bit address space.
