Max. CPU clock rate. The P6 microarchitecture is the sixth-generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. It is frequently referred to as i686. [ 2] It was planned to be succeeded by the NetBurst microarchitecture used by the Pentium 4 in 2000, but was revived for the ...
AMD Athlon (early version), a technically different but fully compatible x86 implementation. x86 (also known as 80x86 [3] or the 8086 family [4]) is a family of complex instruction set computer (CISC) instruction set architectures [a] initially developed by Intel based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
Cryptographic (e.g. RDRAND, AES-NI) Discontinued (e.g. 3DNow!, MPX, XOP) v. t. e. The x86 instruction set refers to the set of instructions that x86 -compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
Pentium (original) Max. CPU clock rate. The Pentium (also referred to as the i586) is a x86 microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium brand. [ 3][ 4] Considered the fifth generation in the 8086 compatible line of processors, [ 5] its implementation and microarchitecture was internally called P5.
The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [ note 1] is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new ...
The Pentium Pro is a sixth-generation x86 microprocessor developed and manufactured by Intel and introduced on November 1, 1995. [1] : . D-2 It introduced the P6 microarchitecture (sometimes termed i686) and was originally intended to replace the original Pentium in a full range of applications. Later, it was reduced to a more narrow role as a ...
Physical Address Extension. In computing, Physical Address Extension ( PAE ), sometimes referred to as Page Address Extension, [1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2] It defines a page table hierarchy of three levels (instead ...
IA-32 (short for " Intel Architecture, 32-bit ", commonly called i386[ 1][ 2]) [ 3] is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985. IA-32 is the first incarnation of x86 that supports 32-bit computing; [ 4] as a result, the "IA-32" term may be used as a ...
