What is intel VT Virtualization Technology ?

Intel Virtualization Technology (Intel VT) is a set of hardware enhancements to Intel server and client platforms that provide software-based virtualization solutions. Intel VT allows a platform to run multiple operating systems and applications in independent partitions, allowing one computer system can function as multiple virtual systems.

What is Hyper Threading Technology ? HT

What is Hyper Threading HT ?.

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.

With Hyper-Threading, a microprocessor's "core" processor can execute two (rather than one) concurrent streams (or thread s) of instructions sent by the operating system. Having two streams of execution units to work on allows more work to be done by the processor during each clock cycle . To the operating system, the Hyper-Threading microprocessor appears to be two separate processors. Because most of today's operating systems (such as Windows and Linux) are capable of dividing their work load among multiple processors (this is called symmetric multiprocessing or SMP ), the operating system simply acts as though the Hyper-Threading processor is a pool of two processors.

What is Intel Turbo boost Technology ?

What is turbo Boost Technology ?

Intel® Turbo Boost Technology 2.01 automatically allows processor cores to run faster than the rated operating frequency if they’re operating below power, current, and temperature specification limits.

Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests a frequency higher than the rated frequency of the processor.  Whether the processor enters into and the amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.

Maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. Intel Turbo Boost Technology frequency varies depending on workload, hardware, software and overall system configuration.

Due to varying power characteristics, some parts with Intel Turbo Boost Technology 2.0 may not achieve maximum turbo frequencies when running heavy workloads and using multiple cores concurrently.

Availability and frequency upside of Intel Turbo Boost Technology 2.0 state depends upon a number of factors including, but not limited to the following:

• Type of workload
• Number of active cores
• Estimated current consumption
• Estimated power consumption
• Processor temperature

When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize frequency and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its TDP configuration and data sheet specified power for short durations to maximize performance.

What is Clock Speed?

Question :- What is clock Speed ?

Ans:- Clock speed is a measure of how quickly a computer completes basic computations and operations. It is measured as a frequency in hertz (Hz), and most commonly refers to the speed of the computer's Central Processing Unit (CPU). While computer developers and users can refer to this term regarding CPU performance, this has fallen out of favor as CPUs have become more complex. The easiest ways to boost clock speed in a computer include upgrading components and "overclocking" a piece of hardware.

Question :- What Clock Speeds Measure ?

Ans:- There is a small quartz crystal inside of a CPU that vibrates at a particular oscillation or frequency. This frequency sets the "speed" of processes in the computer and is usually very high; they are typically measured in megahertz (MHz) and gigahertz (GHz). A megahertz is one-million cycles per second, while a gigahertz is one-billion cycles per second. So a computer with a clock speed of 800 MHz is running 800,000,000 cycles per second, while a 2.4 GHz computer is running 2,400,000,000 cycles per second.

These cycles set the speed for all processes within a computer. This ensures that all components and memory are working together at a rate that remains harmonious. Different components and processes can also run as a fraction of the primary CPU speed, which allows each element of a computer to work on its own and still function with the primary frequency of the CPU .

Question :- How to Improving CPU Performance

Ans :- There are a number of ways in which a computer user can increase the speed of his or her computer. Upgrading an older CPU to a new one, for example, can provide hardware with a higher clock speed or multiple "cores." Multi-core processors are essentially two or more CPUs in one, which offer greater performance for software programs that can take advantage of multiple cores.

It is also possible to "overclock" a processor. This basically increases the clock speed of a CPU beyond what is recommended by the manufacturer, allowing the computer to run faster. Overclocking a CPU is not generally recommended, however, as it produces additional heat that can damage the processor or other components and typically voids most computer's warranties.
