M1 Oem Cpuhruskaextremetech: The first thing you need to know is that a M1 CPU is an electronic component and not the computer’s processor. The latter deals with the instruction set, while the former is used to interpret those instructions. In other words, it’s a chip that implements instruction sets like x86 ones. It can also be thought of as an interface devi
ed from the processor that allows the hardware to talk to your computer. In this case, it’s a bus adapted for processors.
The M1 CPU
M1 is an acronym for “Microprocessor 1”. The CPU was introduced by Intel in 1982. This is the first and still one of the best desktop microprocessors ever made. It had been designed with a pico-cell (4 kilobyte) 32-bit internal register set and ran at 1,800 MHz. It could do 32-bit single-precision floating point math, intended for scientific and financial applications. In fact, the M1 was never meant to be a general purpose CPU at all.
The M1 was discontinued in 1986. There were two mobile versions of the M1: 1 MHz and 2 MHz, respectively, but also a much faster version, known as the 80386 (the 386 is THE CPU most used in PCs today). The 386 version was introduced in 1987. The M1 was sold through the end of 1987, if memory serves.
In the mid 80ies, there was a turf war between Intel, Motorola and AMD. AMD wanted a home-grown CPU and chose to go with the 80386 (also known as 386 or i386). Intel’s answer came with the 80286 (286 is an abbreviation for “microprocessor”, like 386). This was the first version of Intel’s classic processor. It was produced in quantity between September 1987 and January 1994, running at 11 MHz to 20 MHz.
The 8086
The 8086 is a real charm for those who want to geek out. It’s the Intel’s mainstream CPU that could be used in both a PC and a mainframe. It had been designed by engineers from Intel (based on the MOS technology) and implemented as an 80×86 machine with 32-bit internal registers. These are called x87 micro-operations. The 8086 was sold between the years 1982 and 1992, and the first models could reach speeds of up to 5 MHz.
The 80286
The 80286 is a companion processor that shared the same memory bus with its parent (80386), but it was a bit faster. It also had a 32-bit internal register set and ran at 10 MHz, like its parent. It was introduced in 1982 as a follow up for the 8086. The 80286 was sold between 1982 and 1994, although the first editions were available until 1988. It is considered history’s best-selling 32-bit CPU.
The 80386
The 80386 is the system processor that most computers use at present. It’s history’s best 32-bit computer CPU and the first to be certified compatible with the Intel bus of its predecessor (80286). It was introduced in 1988 and sold until 1994. It runs at 16 MHz, but its latency is adjustable from 20 to 60 nanoseconds (depending on the used models). The chip is capable of doing up to 20 MIPS.
The 80486
The 80486 could be thought of as a turbocharged 8086. Even though it’s a superset, its registers are two bits wider than a 8086’s – 32 bits instead of 24. This means that it’s able to do two additional instructions per clock cycle. This is a trick called superscalar execution and was first used on this chip. The 80486 is an incredible processor for the mid-90’s, when the CPU clock was more important than the total number of instructions the processor could execute per second.
The Pentium and Pentium Pro
The Pentium is Intel’s mainstream mobile CPU that has been designed using RISC architecture. It runs at 3-5 GHz, has a few extra registers (16 instead of 12) and has a 32-bit internal register set.
