Glossary:X86
x86 is the Intel CPU architecture derived originally from the 8086 chip, released in 1978. Subsequent generations of chip were the 80286 (often referred to simply as 286), 386, 486 and 586 also known as Pentium. From 386 on, these were all 32 bit architectures, but since the mid to late 2000's the x86 architecture has been largely superseded by AMD64, though AMD64 processors retain the capability to run code written for x86.
