HT Technology (Hyperthreading)
Intel's HT Technology (hyperthreading) allows a single processor or processor core to run two sets of instructions at the same time. HT Technology essentially divides a single physical processor core into two virtual processors.
In March 2002, HT Technology released Xeon workstation-class CPUs with a 533MHz system bus. It first appeared in regular desktop PC CPUs in November 2002, with the Pentium 4 3.06GHz processor. Because HT Technology predates multicore processors, it may or may not be supported by processors with multiple physical cores, like the Core 2 and Core i-series, depending on the exact processor version. A quadcore CPU with HT Technology (such as Intel's Core i-series) would appear to the OS as an 8-core processor; the Core i7-5960X has eight cores and supports up to 16 threads. An HT-enabled processor includes two sets of general-purpose registers, control registers, and other design components for each core, but the cache, execution units, and buses are shared by both logical processors. Each logical processor is responsible for a single thread during operations.
With HT Technology-enabled, a processor may fill otherwise idle time with a second process for each core, improving multitasking and single-threading application performance.
The CPU models are shown using four 3 x 9 grids that are shaded according to the number of threads they manage. When the CPU is idle, thread 1 is represented by black, thread 2 by grey, and the blocks are left white or blank. The single CPU model is made up of a single 3 cross 9 grid, with the majority of the grid colored in black and the rest blank or white. The Dual-physical CPUs are made up of two 3 cross 9 grids, the first of which is colored in black and the second in grey, with a few empty blocks in both grids. The Hyper-threaded CPU is made out of a single 3 cross 9 grid with black and grey coloring and a few blank blocks.
Although the overall performance of an HT-enabled machine isn't as fast as a CPU with as many physical cores, speed increases of up to 25% are possible when multiple applications or multithreaded applications are running.
You'll need the following to make use of HT Technology:
Processor with HT Technology Support: Many (but not all) Core i-series, Pentium 4, Xeon, and Atom CPUs fall within this category. To be sure, check the CPU specs for your individual model.
Chipset compatibility: HT Technology may not be supported by some older chipsets.
BIOS support for enabling/disabling HT Technology: Make sure HT Technology is enabled in the BIOS Setup.
HT Technology enabled OS: HT Technology is supported by Windows XP and later. HT Technology is supported by Linux distributions with kernels 2.4.18 and above. You may check the Device Manager in Windows to see how many CPUs are detected to determine if HT Technology is working properly. The Windows Device Manager displays twice as many processors as there are physical CPU cores when HT is supported and activated.
