Hyper-Threading Technology is a form of simultaneous multithreading technology introduced by Intel, while the concept behind the technology has been patented by Sun Microsystems. Architecturally, a processor with Hyper-Threading Technology consists of two logical processors per core, each of which has its own processor architectural state.
The Intel Pentium 4 was the first modern desktop processor to implement simultaneous multithreading, starting from the 3.06 GHz model released in 2002, and since introduced into a number of their processors. Intel calls the functionality Hyper-Threading Technology, and provides a basic two-thread SMT engine
Multithreading (computer architecture) For threads in software, see Thread (computing). 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.
Coffee Lake is Intel 's codename for its eighth-generation Core microprocessor family, announced on September 25, 2017. [5] It is manufactured using Intel's second 14 nm process node refinement. [6] Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 ...
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.
Kaby Lake. Max. CPU clock rate. Kaby Lake is Intel 's codename for its seventh generation Core microprocessor family announced on August 30, 2016. [7] Like the preceding Skylake, Kaby Lake is produced using a 14 nanometer manufacturing process technology. [8] Breaking with Intel's previous "tick–tock" manufacturing and design model, Kaby Lake ...
Processor affinity can effectively reduce cache problems, but it does not reduce the persistent load-balancing problem. [2] Also note that processor affinity becomes more complicated in systems with non-uniform architectures. For example, a system with two dual-core hyper-threaded CPUs presents a challenge to a scheduling algorithm.
The Pentium II Xeon was a " Deschutes " Pentium II (and shared the same product code: 80523) with a full-speed 512 kB (1 kB = 1024 B), 1 MB (1 MB = 1024 kB = 1024 2 B), or 2 MB L2 cache. The L2 cache was implemented with custom 512 kB SRAMs developed by Intel. The number of SRAMs depended on the amount of cache.
