7 Most Common Questions about Processors

IT | Feb 11, 2018 |

1.What is a HyperThreaded Processor?
Part of the Programming glossary: Hyper-Threading is a technology used by some Intel microprocessor s that allows a single microprocessor to act like two separate processors to the operating system and the application program s that use it. It is a feature of Intel’s IA-32 processor architecture.

2.How many Threads are in a Core?
You have 4 CPU sockets, each CPU can have, up to, 12 cores and each core can have two threads. Your max thread count is, 4 CPU x 12 cores x 2 threads per core, so 12 x 4 x 2 is 96. Therefore the max thread count is 96 and max core count is 48.

3.What is a Logical Processor?
Physical cores are just that, physical cores within the CPU. Logical cores are the abilities of a single core to do 2 or more things simultaneously. This grew out of the early Pentium 4 CPUs ability to do what was termed HyperThreading (HTT).

4.What is a Virtual Core Processor?
A virtual core is a CPU with a separation between two areas of the processor.Virtual cores take on some of the processing of the computer without interfering with the other area. As opposed to physical cores, which has something that physically separates the cores, virtual cores do not have physical separation.

5.What does HyperThreading Mean?
Hyperthreading (officially called Hyper-Threading Technology or HT Technology, and abbreviated as HTT or HT) is Intel’s proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations (doing multiple tasks at once) performed on x86 microprocessors.

6.What is a thread in a Processor?
It means that the CPU has 2 physical cores but can process 4 threads simultaneously through hyperthreading or Simultaneous multithreading (SMT). In reality, one physical core can only truly run one thread at a time, but using hyperthreading, the CPU exploits the idle stages in the pipeline to process another thread.

7.What is the Difference b/w HyperThreading and Multi-Threading?
HyperThreading is a commercial trademark for Intel’s proprietary implementation of SMT. Simultaneous multithreading (a.k.a. hyperthreading) allows a different thread to execute every cycle. This is possible because the hardware includes support to quickly switch between threads.

The countdown has started for Windows 7


Jan 17, 2019 | Category: Microsoft | Comments

Microsoft will stop free support by 2020.

It has been known for a long time that the official support for Windows 7 is nearing the end. January 14, 2020, is the date, then Microsoft will no longer provide free support to users of this OS and security updates will stop. You will still be able to use Windows 7, but in many ways, you will be left to yourself, at your own risk.
