In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. [1]
reengineered P6-based microarchitecture used in Intel Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
AMD K7 Athlon – microarchitecture of the AMD Athlon classic and Athlon XP microprocessors. Was a very advanced design for its day. First generation was built with a separate L2-cache chip on a board inserted into a slot and introduced extended MMX. The second generation returned to the traditional socket form factor with fully integrated L2 ...
The Turing microarchitecture combines multiple types of specialized processor core, and enables an implementation of limited real-time ray tracing. [4] This is accelerated by the use of new RT (ray-tracing) cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual triangles.

Zen 5 ("Nirvana") [1] is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022, [2] launched for mobile in July 2024 and for desktop in August 2024. [3] It is the successor to Zen 4 and is currently fabricated on TSMC's N4X process. [4] Zen 5 is also planned to be fabricated on the N3E process in the future. [5]
The Intel Core microarchitecture (provisionally referred to as Next Generation Micro-architecture, [1] and developed as Merom) [2] is a multi-core processor microarchitecture launched by Intel in mid-2006. It is a major evolution over the Yonah, the previous iteration of the P6 microarchitecture series which started in 1995 with Pentium Pro.
The microarchitecture is the same as in the six-core Gulftown/Westmere-EP processor, but it uses the LGA 1567 package like Beckton to support up to eight sockets. Starting with Westmere-EX, the naming scheme has changed once again, with "E7-xxxx" now signifying the high-end line of Xeon processors using a package that supports larger than two ...
