How To Find The Clock Speed Of My Computer

Are you familiar with the clock rate of your CPU? If you are a computer user, then you know that your computer'southward CPU works like a encephalon on your computer. Your computer operation most of the time depends on the functioning of your CPU. Performance of a CPU most of the time depends on the clock charge per unit of CPU. Then, if y'all desire to empathise the things that are responsible for the performance of a CPU, you lot should know what is clock rate of a CPU. Get through this article to know all about clock rate of a CPU.

What is Clock Cycle of CPU

Yous may know what is CPU in a computer. CPU is like a brain in a computer like a encephalon in a living kind. So, the speed of a computer is generally depended on the speed of its CPU. Clock Cycle is referred to the speed of a CPU. The clock cycle is the amount of time betwixt two Cycles. During a clock bicycle, one or more than instructions are candy. Then, if a CPU tin procedure a higher number of pulses per second, it will exist able to process information at a high speed.

What is Clock Rate of CPU

You lot may have seen in your CPU clarification that your CPU clock speed is ane-three GHz. Have you wondered what does that mean? Really, it is your CPU'southward clock rate. Clock rate means the number of pulses generated by CPU in one 2nd. It is generally measured in MHz (Megahertz) or GHz (Gigahertz). Today's computers mostly run at a clock rate having more than one Gigahertz. More often than not, clock speed or clock rate is determined by a quartz-crystal excursion.

History of Clock Speed in CPU

If yous wait back to 1980, you will find that Intel 8088 processor was quite popular at that time. You lot will exist surprised to know that this CPU has only a clock speed of 4.77 MHz. CPU clock speed and then started doubling every yr. Today, if yous buy a cheap estimator, it will have a CPU that has a clock speed of at to the lowest degree 1 GHz. Nowadays, a CPU having a clock speed of around 3 GHz is then common.

How Does Clock Speed Affect the CPU Operation

Think of your brain. How practice you decide the speed of a person's brain? The fast he tin can think and make up one's mind determine the speed of his brain. It is same for CPU of a computer. The fast a CPU tin can procedure instructions, the faster the CPU. CPU's clock charge per unit determines how fast a CPU tin can piece of work. The speed of a CPU is the rate at which a CPU tin can consummate a processing cycle. You know about the clock cycle.

Suppose, your CPU's clock rate is i GHz. If your friend has a CPU which clock charge per unit is 2 GHz, and so your friend'due south CPU'south clock speed is twice of your CPU's. But information technology cannot be said that the 2 GHz CPU is 2 times faster than the 1 GHz CPU. It depends on many things including calculator architecture. Suppose, the 2 GHz CPU can complete an education in 4 Cycles and the 1GHz CPU needs vi Cycles to complete the same instruction then the 2 GHz CPU will perform the same operation more than than ii times faster than the ane GHz CPU.
If the situation is opposite, that means, the ii GHz CPU needs more cycles than the 1 GHz CPU to perform the same operation, then the 2 GHz CPU will piece of work less than 2x fast than the 1 GHz CPU.

Other Factors That Make up one's mind the Functioning of a Reckoner

Computer operation depends on the processing speed of a computer. The Clock speed cannot determine the processing speed of a reckoner. It is ane measure out of calculator power. Suppose, you have only doubled the clock speed, will your CPU work ii times faster than before? The respond is, no. Information technology depends on many other things. The functioning of a CPU depends on

1. The type of microprocessor
2. The bus architecture
3. The nature of the instructions prepare
4. The amount of Random Access Retention (RAM) etcetera

Some processors can execute only 1 instruction during a clock cycle. Near of the today's CPUs tin can execute more than than one instructions per clock bike. So, the CPUs that can complete more than instructions per bike than others will work faster. In the same way, the computer with a 64-bit bus compages will work faster than the estimator work in a 32-flake omnibus compages. So, y'all cannot find whatever simplistic or universal relation among clock speed, autobus architecture.

Clock Rate Formula

CPU clock rate formula tin be determined in many ways. Hither we volition talk about two formulas to determine the performance of a CPU. To sympathise that you have to know about instructions, CPI, Clock cycle time, Clock rate. Y'all have known all these from previous sections of this commodity except CPI.

CPI: You take known well-nigh Clocks and instructions. CPI stands for Clocks per Instructions. That means, how many clocks are needed to consummate an pedagogy.

Equations:

CPU Time = I * T * CPI

Here,

I = Total number instructions in a program

CPI = Clocks needed to complete an instruction

T = Clock cycle time

CPU Time = I * CPI/R

Hither,

R = Clock rate which can be measured by the inverse of Clock cycle time that ways, R = 1/T

Annotation: T or R are more often than not measured for knowing the functioning of a processor. I require special profiling software. CPI depends on many other factors such every bit RAM, calculator architecture etcetera.

Fastest CPU Clock Speed

It is a hard thing to say almost the fastest clock speed. Because clock speed is depended on many things including cooling process, motherboard etcetera. Again, overclocking of a CPU can give higher clock speed. Vendors including AMD, Intel are manufacturing CPU having a clock speed of above 8 GHz. The clock speed of 8722.78 MHz was recorded as the globe'due south fastest clock speed until this commodity was written. The CPU is AMD FX-8370. The user of this CPU was The Stilt and liquid nitrogen cooling system was used.

Annotation: Nosotros haven't discussed the clock speed of CPUs that are used in supercomputers.

Multi-Cores vs Multi-Processors

Before 2005, all processors on the market had a single core. And then, clock speed was the main scale to measure the performance of a CPU. But nowadays, processors with multi-cores are common. Fifty-fifty a very cheap laptop present comes with at least two or three cores. Even processors with multiple processors are becoming available. Each processor in the processor has multiple cores also.

Multi-core processors became popular because a processor having a single core cannot be given likewise much clock speed because of technological limitations. A cadre of a processor is a unmarried processing unit of measurement. So, a multi-core processor has multiple processing units. A 2.0 GHz dual-core processor has two processing unit each having 2.0 GHz clock speed that comprising 4 GHz clock speed. So, a 5 core two GHz processor has a total clock speed of 10 GHz.

Clock Speed vs Cores

You at present know the benefit of having a multi-core processor with a higher clock speed. But having also many cores with a higher clock speed is non possible most of the time considering of the toll. And so, it becomes hard to choose a processor for buying. Y'all can go for a processor having slower clock speed but many cores, or you can go for a processor having higher clock speed only fewer cores. To understand this affair, nosotros are giving y'all pros and cons of these two possible choices.

Processor Having More than Cores but Slower Clock Speed

Pros:

1. It will give more than benefits to the applications that support multi-threading
2. Information technology is a cost-effective mode of increasing functioning
3. This kind of processor can run more applications at in one case

Cons:

1. This kind of processors cannot requite a higher single-threaded performance.

Processor Having Fewer Cores but Higher Clock Speed

Pros:

1. This kind of processors tin give a higher single-threaded performance.
2. Lower toll option

Cons:

1. It cannot give more benefits to the applications that support multi-threading
2. Many cores are not available to carve up between applications
