The Intel 80386, also known as the i386 or just 386, is a 32-bit microprocessor introduced in 1985. The first versions had 275,000 transistors and were the first Pentium-compatible CPUs. The 32-bit386 can generate both real-mode and protected-mode instructions. Protected mode allows for multitasking, paging and other features that are not available in real mode. The386 was one of the first microprocessors to support virtualization.
The Intel 80386 was the successor to the 8086 and was followed by the Pentium and Pentium Pro processors. What is the speed of 80386 microprocessor? The speed of a microprocessor is typically measured in terms of its clock speed, which is the number of clock cycles that the processor can execute per second. The clock speed of the 80386 microprocessor is 16 MHz. Is 80386 a microprocessor? Yes, the 80386 is a microprocessor. It was introduced in 1985 and was the first 32-bit microprocessor from Intel. It had a 32-bit data bus and a 16-bit address bus. It was used in the IBM PC/AT and many other personal computers.
Is i386 still used? The i386 microprocessor is still used in many laptop and desktop computers. However, it is not as common as it once was. The i386 was first released in 1985 and was the first microprocessor to be used in personal computers. It was used in the IBM PC, the Apple Macintosh, and the Commodore Amiga. The i386 was replaced by the i486 in 1989, which was itself replaced by the Pentium in 1993. How much RAM did a 386 have? The original IBM PC/AT, released in 1984, came with a whopping 256 kilobytes of RAM. The subsequent model, the IBM PC/AT 5170, came with 512 kilobytes of RAM. The top-of-the-line model, the IBM PC/AT 5270, came with a whopping one megabyte of RAM. How fast is 386? The speed of a 386 microprocessor is determined by its clock rate, which is the number of cycles per second that the microprocessor can execute. The clock rate of a 386 microprocessor can range from 12 MHz to 40 MHz.
