There are several ways in which CPU speed can be measured. The most common unit is a hertz, such as 3 gigahertz. 1 hertz is another name for 1 CPS. A CPS is a Cycle Per Second. So 3 gigahertz would mean that the CPU is doing roughly 3 billion cycles per second. (A giga in computer speak means billion.)

This was the most common form of measurement during the Pentium Chip era. The last Pentium chips were reaching 3.8 gigahertz. However, you may notice that newer chips such as the Core series by Intel have much fewer hertz, but run much faster. That is because the CPU manufactures learned that there are better ways to make a CPU faster than just by increasing the hertz.

With newer CPUs they have put two or more processor cores on the same chip. These processor cores work in tandem. By working together and sharing the processing load, the overall speed of the computer is greatly improved despite the fact that they are running at slower hertz speeds.

Another way to measure the speed of a CPU is by using FLOPS (FLoating Operations Per Second). 1 FLOPS is generally considered 1 addition or multiplication operation in the processor, however FLOPS also pertain to exponential, sine and cosine. FLOPS do not have as much merit in home computing as they do in research super computers because research uses more mathematical types of computation.

It is hard to compare actual FLOPS between CPU architecture. A Graphics Card Processor (GPU) would consider an exponential 1 FLOPS while it would take many FLOPS on a normal CPU. GPUs can compare FLOPS much better than CPUs because they do use mathematical calculations for their graphics rendering.

Some basic FLOPS highpoint counts of Processors as of Jan 2010 are as follows:
Pentium 4 - 7 gigaflops
Core2 Quad - 70 gigaflops
Xbox 360 CPU - 115 gigaflops
Playstation 3 CPU [Cell Processor] - 218 gigaflops
Xbox 360 GPU - 240 gigaflops
Playstation 3 GPU - 1800 gigaflops (1.76 teraflops)
nVidia Geforce GTX 295 [top PC graphics card now] - 1788 gigaflops (1.75 teraflops)
Jaguar [top super computer now] - 1,759,000 gigaflops (1.75 petaflops)
Folding@Home Distributed Computer [as of now] - 8,500,000 gigaflops (8.10 petaflops)

8.10 petaflops is 9.11978925 x 1015 FLOPS or 9,119,789,250,000,000 mathematical operations per second!

What is the speed of a CPU?

there are different speeds... you can tell what your speed is my right clicking my Computer and going to properties. depending on your OS you might have to click the general t

What determines the speed of a CPU?

The speed of a CPU depends on the number of core processors and the speed at which these run ( generally measured in GHz). The higher the speed, and the more cores, the faster

What is one other place not in windows or any documentation where you could determine the CPU CPU speed and amount of ram installed on your system?

You can find this in your BIOS. You can reach this area of your PC in different ways. Like in Dell you press F2 on you keyboard when you see the the dell logo on your display,

How can you determine the CPU speed?

four main things determine a cpu's speed: 1. The processor 2. The hard drive 3. The mother board 4. Ram drive and stick In order to have your computer truly fast the first thr

The speed of the CPU is determined by?

The Speed of a CPU or Central Processing Unit is determined by Hz, Mhz, Ghz. These are all frequencies and tell you how many calculations it can do at a time. 1 Ghz is 1000

What are the speeds of various CPUs?

The CPU speed, and processor speed is the amount of cycles that aCPU can perform per second.CPU speed is not a good indicator of CPUperformance.

CPU clock speed is measured in?

CPU speed is often measured in Hertz [Hz] which is simply cycles per second. One thousand Hertz = 1kHz (kilohertz) One million Hertz = 1MHz (Megahertz One billion Hertz

What does a CPU determin?

CPU - The Central Processing Unit or the processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element

Speed of the CPU measured in?

There is no one measurement of CPU speed. Different CPU's may perform differently on various tasks. For instance, you might find something like this: CPU 'A' runs program 1 i

What factors determine CPU perfomance?

It actually depends up on many factors like which processor u r using , size of RAM(Random Access Memory) , and many more factor but they are depends on the processor like reg
