The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.

The 80386 is an advanced 32-bit microprocessor optimized for multitasking operating systems and designed for applications needing very high performance. The 32-bit registers and data paths support 32-bit addresses and data types. The processor can address up to four gigabytes of physical memory and 64 terabytes (246 bytes) of virtual memory.

2019年1月21日 · The Intel 80386 is the next step in the evolution of the processor series that started with the Intel 8086 (which was itself inspired by the Intel 8080, which was in turn inspired by the Intel 8008). Even at this early stage, it had a long history, which helps to explain many of its strange corners.

80386 Microprocessor is a 32-bit processor that holds the ability to carry out 32-bit operation in one cycle. It has data and address bus of 32-bit each.

The Intel 80386 is a 32-bit microprocessor that helped to launch the Windows era. Thanks to its incorporation of advanced memory management circuitry, the enables programs to switch from real mode to protected mode without rebooting; in short, they made protected- mode operating systems and applications possible for the first time.

2023年9月2日 · The 80386 is the most important CPU Intel ever produced. It confirmed the importance of the x86 line and sparked a computing revolution. And yet it almost never saw the light of day. This is the history of the 386 and why it was such a landmark.

2025年3月10日 · The third x86 generation of x86 microprocessors, Intel 80386 (i386) was a 32-bit microprocessor backwards compatible with previous generations of 80x86 CPUs. Major new feature in the i386 CPU was 80386 protected mode - this mode fixed many shortcomings that existed in the 80286 processor and in the 80286 protected mode:
