The x86 was introduced in 1986.
The x86 serves as an excellent example of CISC design.
The x86 architecture is used in a wide variety of embedded systems.
Any program written on an older version of the x86 architecture can execute on newer versions.
The x86 was introduced with a clock speed of 5 MHz
The x86 was introduced with 64,000 transistors.
All changes to the x86 instruction set architecture have involved additions or subtractions to the
instruction set.
The 8086 is the first appearance of the x86 architecture.
The 8086 was the world’s first general- purpose microprocessor.
The 8086 was used in the first personal computer.
The 8086 was an 8-bit machine, with an 8-bit data path to memory.
The 8086 sported an instruction cache, or queue, that prefetches a few instructions before they
are executed.
The 80286 was an extension of the 8086 and the first Intel processor to support multitasking.
The 80286 was Intel’s first 32-bit machine.
The 80386 extension of the 8086 enabled addressing a 16-MB memory instead of just 1 MB.
The 80486 introduced the use of sophisticated instruction pipelining.
The 80486 offered a built-in math coprocessor, offloading complex math operations from the
main CPU.
Pentium was the first Intel x86 microprocessor with a dual core.
Pentium introduced the use of superscalar techniques, which allow multiple instructions to
execute in parallel
Pentium II extends the Core architecture to 64 bits.
