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 ...

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 ...
The Athlon 64 is a ninth-generation, AMD64 -architecture microprocessor produced by Advanced Micro Devices (AMD), released on September 23, 2003. [1] It is the third processor to bear the name Athlon, and the immediate successor to the Athlon XP. [2] The Athlon 64 was the second processor to implement the AMD64 architecture (after the Opteron ...
A 64-bit word can be expressed as a sequence of 16 hexadecimal digits. In computer architecture, 64-bit integers, memory addresses, or other data units [ a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses ...
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.
AMD Turion is the brand name AMD applies to its x86-64 low-power consumption mobile processors codenamed K8L. [1] The Turion 64 and Turion 64 X2/Ultra processors compete with Intel's mobile processors, initially the Pentium M and the Intel Core and Intel Core 2 processors.
Below is a list of microarchitectures many of which have codenames associated: [2] AMD K5 – AMD's first original x86 microarchitecture. The K5 was based on the AMD 29k microarchitecture with the addition of an x86 decoder. Although the design was similar in idea to a Pentium Pro, the actual performance was more like that of a Pentium.
