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.
Intel Xeon Phi has 4-way SMT (with time-multiplexed multithreading) with hardware-based threads which cannot be disabled, unlike regular Hyper-Threading. [8] The Intel Atom , first released in 2008, is the first Intel product to feature 2-way SMT (marketed as Hyper-Threading) without supporting instruction reordering, speculative execution, or ...
All models support: MMX, SSE, SSE2, SSE3, Hyper-threading, Intel 64, XD bit (an NX bit implementation) Intel VT-x supported by: 6x2 e.g. Model 662 and 672; Enhanced Intel SpeedStep Technology (EIST) supported by: all except 620. Transistors: 169 million; Die size: 135 mm 2; Steppings: N0, R0
Later versions introduced Hyper-Threading Technology (HTT). The first Pentium 4-branded processor to implement 64-bit was the Prescott (90 nm) (February 2004), but this feature was not enabled. Intel subsequently began selling 64-bit Pentium 4s using the "E0" revision of the Prescotts, being sold on the OEM market as the Pentium 4, model F.
Overall efficiency varies; Intel claims up to 30% improvement with its Hyper-Threading Technology, [1] while a synthetic program just performing a loop of non-optimized dependent floating-point operations actually gains a 100% speed improvement when run in parallel.
HyperTransport (HT), formerly known as Lightning Data Transport, is a technology for interconnection of computer processors. It is a bidirectional serial/parallel high-bandwidth, low-latency point-to-point link that was introduced on April 2, 2001. [1] The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology.
The NetBurst microarchitecture includes features such as Hyper-threading, Hyper Pipelined Technology, Rapid Execution Engine, Execution Trace Cache, and replay system which all were introduced for the first time in this particular microarchitecture, and some never appeared again afterwards.
