What is the clock speed of the CPU?

Answer 1

There's no real way to determine the "average clock speed" of a CPU, unless you can account for every microprocessor ever made. Microprocessors, including those used for central processing units, have ranged in speeds from 500 KHz to 6 GHz.

Answer 2

Also called clock rate, the speed at which a microprocessor executes instructions. Every computer contains an internal clock that regulates the rate at which instructions are executed and synchronizes all the various computer components. The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second. Clock speeds are expressed in megahertz (MHz) or gigahertz ((GHz). The internal architecture of a CPU has as much to do with a CPU's performance as the clock speed, so two CPUs with the same clock speed will not necessarily perform equally. Whereas an Intel 80286 microprocessor requires 20 cycles to multiply two numbers, an Intel 80486 or later processor can perform the same calculation in a single clock tick. (Note that clock tick here refers to the system's clock, which runs at 66 MHz for all PCs.) These newer processors, therefore, would be 20 times faster than the older processors even if their clock speeds were the same. In addition, some microprocessors are superscalar, which means that they can execute more than one instruction per clock cycle. Like CPUs, expansion buses also have clock speeds. Ideally, the CPU clock speed and the bus clock speed should be the same so that neither component slows down the other. In practice, the bus clock speed is often slower than the CPU clock speed, which creates a bottleneck. This is why new local buses, such as AGP, have been developed.

Answer 3

It is the speed taken by a microprocessor in the CPU to execute instructions.. It is often measured in MHz and most often GHz. The faster the rate is the faster your computer can perform calculations and do instructions..

Answer 4

These are terms that have become somewhat disconnected from reality nowadays. System speed usually refers to the rate at which data can be shuffled around in a PC and it varies from peripheral to peripheral (sound cards, RAM, HDs, etc..). In a modern PC, the rate for the Front Side Bus is frequently used for this number. These are typically numbers like 233MHz, 333MHz, 533MHz or 1066MHz (MHz is Mega Hertz, or millions of cycles per second). This brings us to the second part, Clock Frequency, and where reality and specifications depart company. A clock is a time base used to synchronize other clocks, like the Front Side Bus and CPU. Typically, these low frequency clocks are multiplied to get all of the other frequencies for the system. A clock of 133MHz is fed to the CPU which multiplies it by 16 to get the CPU clock of 2.13GHz and by 8 to get the Front Side Bus speed of 1066MHz.

Answer 5

The system clock is a very fast and accurate electronic timer used to synchronised data transfer at a specific clock pulse. A faster system clock means that the number of instructions executed by the CPU per second is higher.

Answer 6

The clock speed of a computer is the speed at which the CPU (central processing unit) runs, in the older computers it was a maximum of 236 MHz, but now a computer's clock speed can go as fast as 4.0 GHz!

Answer 7

for a 2000 MHz CPU, the pace of the system clock is 2,000,000,000 ticks per second. The system clock in a PC running any version of Microsoft Windows will run at the same pace as actual time.
