What year did the 486 come out?

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 transistors did the Intel 486 have?

one million transistors
The 486 became the first x86 chip family to exceed one million transistors.

How old is Pentium?

Pentium, family of microprocessors developed by Intel Corp. Introduced in 1993 as the successor to Intel’s 80486 microprocessor, the Pentium contained two processors on a single chip and about 3.3 million transistors.

Why is it called 486?

Why so many companies made 486s and Intel wanted them to stop. At least seven companies made 486-class CPUs and called them by that name. This dates back to IBM’s original requirements for the first IBM PC. IBM wanted multiple sources, in case Intel ever couldn’t meet demand for any reason.

Was there a 186 processor?

The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus.

How did Intel come up with the i486 CPU?

To respond to this new situation Intel wanted to provide a lower cost i486 CPU for system integrators, but without sacrificing the better profit margins of a “full” i486. This was accomplished through a debug feature called Disable Floating Point (DFP), by grounding a certain bond wire in the CPU package.

When did the Intel 80486 microprocessor come out?

The Intel 80486 is a higher performance follow-up to the Intel 80386 microprocessor. Introduced in 1989, it is the first tightly pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating-point unit.

Which is the successor to the Intel 80386?

The Intel 80486, also known as the i486 or 486, is the successor model of 32-bit x86 microprocessor to the Intel 80386. Introduced in 1989, the 80486 improved on the performance of the 80386DX thanks to on-die L1 cache and floating-point unit, as well as an improved, five-stage tightly-coupled pipelined design.

Is the Motorola 68040 compatible with the Intel i486?

The Motorola 68040, while not compatible with the i486, was often positioned as its equivalent in features and performance. Clock-for-clock basis the Motorola 68040 could significantly outperform the Intel 486 chip. However, the i486 had the ability to be clocked significantly faster without suffering from overheating problems.
