Single core processors are still in use in some niche circumstances. Some older legacy systems like those running antiquated operating systems (e.g. Windows 98) cannot gain any benefit from multi-core processors. Single core processors are also used in hobbyist computers like the Raspberry Pi and Single-board microcontrollers. The production of ...

Diagram of a generic dual-core processor with CPU-local level-1 caches and a shared, on-die level-2 cache An Intel Core 2 Duo E6750 dual-core processor An AMD Athlon X2 6400+ dual-core processor. A multi-core processor (MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called ...
Core i7, on the desktop platform no longer supports hyper-threading; instead, now higher-performing core i9s will support hyper-threading on both mobile and desktop platforms. Before 2007 and post-Kaby Lake, some Intel Pentium and Intel Atom (e.g. N270, N450) processors support hyper-threading. Celeron processors never supported it.
Pentium D [2] is a range of desktop 64-bit x86-64 processors based on the NetBurst microarchitecture, which is the dual-core variant of the Pentium 4 manufactured by Intel.Each CPU comprised two cores.
[a] SMT, or Intel's marketing term HyperThreading, allows a single physical CPU core with 2 threads to execute two tasks simultaneously. In the early 2000s, SMT was a way to add more processing threads to dual and quad-core CPUs while not using too much die space. The removal of SMT allows the physical core die area to be reduced.
A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.
