The Intel 486, officially named i486 and also known as 80486, is a microprocessor. It is a higher-performance follow-up to the Intel 386. The i486 was introduced in 1989. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386. It was the first tightly … Se mer The i486 was announced at Spring Comdex in April 1989. At the announcement, Intel stated that samples would be available in the third quarter and production quantities would ship in the fourth quarter. The … Se mer Intel offered several suffixes and variants (see table). Variants include: • Intel RapidCAD: a specially packaged Intel 486DX and a dummy floating-point unit (FPU) … Se mer Early i486-based computers were equipped with several ISA slots (using an emulated PC/AT-bus) and sometimes one or two 8-bit-only slots (compatible with the PC/XT-bus). Many motherboards enabled overclocking of these from the default 6 or 8 MHz to perhaps … Se mer • List of Intel microprocessors • Motorola 68040, although not compatible, was often positioned as the Motorola equivalent to the Intel 486 in terms of performance and features. • VL86C020, ARM3 core of similar time frame and comparable MIPS performance on … Se mer The instruction set of the i486 is very similar to the i386, with the addition of a few extra instructions, such as CMPXCHG, a compare-and-swap atomic operation, and XADD, a fetch-and-add atomic operation that returned the original value (unlike a … Se mer Processors compatible with the i486 were produced by companies such as IBM, Texas Instruments, AMD, Cyrix, UMC, and STMicroelectronics (formerly SGS-Thomson). Some … Se mer The AMD Am5x86 and Cyrix Cx5x86 were the last i486 processors often used in late-generation i486 motherboards. They came with PCI slots and 72-pin SIMMs that were designed to run Windows 95, and also used for 80486 motherboards upgrades. While the Se mer Nettet15. des. 2016 · Intel 486 (1989 – 1994) The 80486DX was released in 1989. It was a 32-bit processor containing 1.2 million transistors. It had the same memory capacity as the 386 (both were 32-bit) but offered twice the speed at 26.9 million instructions per second (MIPS) at 33 MHz. There are some improvements here, though, beyond just speed.
