Intel CoreIntel Core is a line of streamlined midrange consumer, workstation and enthusiast computer central processing units (CPUs) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. The lineup of Core processors includes the Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, along with the X-series of Intel Core CPUs.
X87thumb|Micro-processeur i487SX x87 est un jeu d'instructions orienté calcul en virgule flottante faisant partie de l'architecture de microprocesseurs x86. Les processeurs proposant ce jeu d'instructions sont l'Intel 8087, 80287, 80387, 80487, AMD K6, Pentium, Athlon, Pentium 4 et Athlon 64. À partir du 80486, la plupart des processeurs x86 implémentent ce jeu d'instruction directement dans le processeur principal.

Zen (microarchitecture)Zen is the codename for a family of computer processor microarchitectures from AMD, first launched in February 2017 with the first generation of its Ryzen CPUs. It is used in Ryzen (desktop and mobile), Ryzen Threadripper (workstation/high end desktop), and Epyc (server). Zen (first generation) The first generation Zen was launched with the Ryzen 1000 series of CPUs (codenamed Summit Ridge) in February 2017. The first Zen-based preview system was demonstrated at E3 2016, and first substantially detailed at an event hosted a block away from the Intel Developer Forum 2016.
Zen (first generation)Zen is the codename for the first iteration in a family of computer processor microarchitectures of the same name from AMD. It was first used with their Ryzen series of CPUs in February 2017. The first Zen-based preview system was demonstrated at E3 2016, and first substantially detailed at an event hosted a block away from the Intel Developer Forum 2016. The first Zen-based CPUs, codenamed "Summit Ridge", reached the market in early March 2017, Zen-derived Epyc server processors launched in June 2017 and Zen-based APUs arrived in November 2017.
Zen 2Zen 2 is a computer processor microarchitecture by AMD. It is the successor of AMD's Zen and Zen+ microarchitectures, and is fabricated on the 7 nm MOSFET node from TSMC. The microarchitecture powers the third generation of Ryzen processors, known as Ryzen 3000 for the mainstream desktop chips (codename "Matisse"), Ryzen 4000U/H (codename "Renoir") and Ryzen 5000U (codename "Lucienne") for mobile applications, as Threadripper 3000 for high-end desktop systems, and as Ryzen 4000G for accelerated processing units (APUs).
EpycEpyc est une gamme de microprocesseurs x86-64 pour serveur informatique d'AMD qui utilise la microarchitecture Zen. Epyc a été annoncée pour la première fois en 2017. Les puces Epyc, gravées en 14 nm, proposent jusqu'à 32 cœurs et une fréquence d'horloge de 3,2 GHz. La gamme Epyc concurrence à la gamme Xeon d'Intel. Modèles annoncés en juin 2017. La , a créé une variante de ce SoC pour le marché chinois appelé Hygon Dhyana.
Bulldozer (microarchitecture)La microarchitecture Bulldozer d'AMD, commercialisée à partir de 2011, fait suite à la microarchitecture K10 introduite fin 2007. Les processeurs l'utilisant seront d'abord gravés en . Nouvelle organisation des cœurs : AMD fusionne deux cœurs en un « module », une architecture entre double cœur et SMT (simultaneous multithreading). Une partie des composants sont mutualisés (les unités de calcul sur entiers passent de 3 par cœur K10 à 4 par module Bulldozer, l'unité de calcul en virgule flottante est utilisable par tous les threads d'un module, le cache mémoire de niveau 2 et d'autres composants sont communs).
HyperTransportL'HyperTransport (anciennement Lightning Data Transport ou LDT) est un bus local série/parallèle plus rapide que le bus PCI et qui utilise le même nombre de broches. HyperTransport est une technologie issue des laboratoires Digital. À la suite de la disparition de Digital, le développement fut repris par AMD, IBM et nVidia qui avaient acquis une licence. Le bus hypertransport a connu différentes évolutions offrant une bande passante théorique de : 1.x : : échanges jusqu'à .
Broadwell (microarchitecture)Broadwell is the fifth generation of the Intel Core Processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication. Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there were no low-end desktop CPUs based on Broadwell.
Mobile processorA mobile processor is a microprocessor designed for mobile devices such as laptops, and cell phones. A CPU chip is designed for portable computers to run fanless, under 10 to 15W, which is cool enough without a fan. It is typically housed in a smaller chip package, but more importantly, in order to run cooler, it uses lower voltages than its desktop counterpart and has more sleep mode capability. A mobile processor can be throttled down to different power levels or sections of the chip can be turned off entirely when not in use.
