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.

2023年1月23日 · Intel 80486 microprocessor was produced at speeds up to 100 MHz. AMD produced even faster 120 and 133 MHz versions of the 80486, and manufactured in small quantities 150 MHz and possibly 166 MHz versions.

Intel released the i486 (also known as the 486 or 80486), the first x86 processor with more than 1-million transistors. The 486 would continue to be Intel's primary x86 processor until the introduction of Pentium in 1993.

The architecture of Intel’s 80486 can be divided into three different sections such as. Bus interface unit (BIU), Execution and control unit (EU), and; Floating-point unit (FU).

2022年11月3日 · The Intel 80486, also known as the i486 or 486, is a higher performance follow-up to the Intel 80386 microprocessor. The 80486 was introduced in 1989 and was the first tightly pipelined x86 design ...

The original 80486, also known as the 486 DX (and sometimes DX2), has 1.2 million transistors using 1 micron technology. This includes the CPU, FPU, and data cache in a single chip. Speeds ranged from 25 MHz to 50 MHz.

2023年12月10日 · What is 80486 (486)? A computer processor developed by Intel as an upgrade to the 386 processor series and commonly called 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.

2016年8月25日 · The Intel 80486 was announced at COMDEX in April 11th 1989, justy 3 years after the 80386 hit the market. The 80486 was really a greatly enhanced 80386. It added a few instructions, on-chip 8KB Write-Thru cache (available off …

The Intel 80486 is the first processor with an in-built 80387 floating-point unit and it is developed in 1989 using CHMOS IV technology. The features of the 80486 processor are given below: It has complete 32-bit architecture which can support 8-bit, 16-bit and 32-bit data types.

Intel's i486 OverDrive processors are a category of various Intel 80486s that were produced with the designated purpose of being used to upgrade personal computers. The OverDrives typically possessed qualities different from 'standard' i486s with the same speed steppings.
