AMD Opteron, the first CPU to introduce the x86-64 extensions in April 2003 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 extension of the x86 instruction set architecture first announced in
Vadem - VG230 and VG330 (SoCs with NEC V30 CPU cores, manufacturing continued by Amphus) [13] SiS (sold its Vortex86 line to DM&P) Intersil (x86 line, that is up to 80286 compatible, discontinued) VAutomation [14] - offered synthesizable x86 cores, in particular the Turbo 186, that has been implemented in ASICs from numerous vendors, e.g. [15]
The x86 architectures were based on the Intel 8086 microprocessor chip, initially released in 1978. Intel Core 2 Duo, an example of an x86-compatible, 64-bit multicore processor AMD Athlon (early version), a technically different but fully compatible x86 implementation
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
Intel Core 2 is a processor family encompassing a range of Intel's mainstream 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. [2]
Intel ships its IA-64 processor line, after repeated delays in getting to market. Now branded Itanium and targeting high-end servers, sales fail to meet expectations. 2003 AMD introduces its Opteron and Athlon 64 processor lines, based on its AMD64 architecture which is the first x86-based 64-bit processor architecture.
AMD has not used K-nomenclature codenames in official AMD documents and press releases since the beginning of 2005, when K8 described the Athlon 64 processor family. AMD now refers to the codename K8 processors as the Family 0Fh processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction.
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.
