hyperthreading

(1) A high-performance computing architecture that simulates some degree of overlap in executing two or more independent sets of instructions. See Hyper-Threading.

(2) (Hyper-Threading) A feature of certain Intel chips that makes one physical CPU appear as two logical CPUs. It uses additional registers to overlap two instruction streams in order to achieve an approximate 30% gain in performance. Multithreaded applications take advantage of the Hyper-Threaded hardware as they would on any dual-processor system; however, the performance gain cannot equal that of true dual-processor CPUs or a CPU with multiple cores.


Hyper-Threading vs. Standard Modes
Applications must be multithreaded in order to take advantage of Hyper-Threading whether in single-core or dual-core machines.

However, for users to see marked improvements through hyperthreading, software applications will need to be rewritten to take advantage of it, and getting developers to tweak their products can take a long, long time.Game review TimeSplitters 2 For GC, Xbox, PS2, Eidos TimeSplitters was one of the first games for the PS2 and really showed what it could do.
Hyperthreading in Intel CPUs allows two threads to run on each CPU core.
According to the Geekbench results, the i5-8520U with hyperthreading is capable of outperforming a current generation i5-7200U in multi-core performance by about 54 percent.
This research is implemented on an Intel quadcore i7, with a speed of 2.53 GHz, and supports hyperthreading. The program is coded in Java under Linux ubuntu 16.
In this era of the World Wide Web, we often use the I term "hyper" to describe mega or massive scale: Hyperlinking, hyperspeed, and hyperthreading all spring to mind.
The chip also includes improved hyperthreading for faster application performance.
* 3.2 GHz Intel Pentium 4 Processor with Hyperthreading
For a more powerful system, Intel's flagship Pentium 4 range now includes "hyperthreading", allowing the processor to perform several tasks simultaneously with no loss in performance.
(Sun does not support the Itanium 2 line of 64-bit chips from Intel, although it has created a version of Solaris 9 for that chip.) Specifically, Solaris 9 now supports the SSE and SSE2 instruction extensions in the Xeon and Opteron processors; it also supports the HyperThreading simultaneous multithreading that Intel offers with the Xeons.
