You are watching: What factors determine the processing power of a cpu
Multiple coresCache memory,clock speed,word length,address bus width,data bus width.
Let’s begin by looking at the many cores
In the Anthony Neuman method, i beg your pardon is the method of computer architecture used by many computers, instructions space fetched and also executed one in ~ a time. Today but we now have actually dual core and quad core computers and each core has actually its own fetch and execute cycle.
This way that a processor deserve to be increase to two or four times much faster than a regular processor . But the actual rate of the processor is dependency on the software program that’s being run.
Not all software will take advantage of the quad and double cores. Game software and video editing software are usually written to take full advantage of this main point technology, whereas native processor software application or spreadsheet software possibly not.
The processor requires a clock pulse in stimulate to operate correctly, so a genuine time clock is detailed to provide the clock pulse.
A computer clock rate is generally in the gigahertz region. The is a exchange rate cycles per second. Typical speeds space two to four gigahertz. The quicker the clock speed, the quicker the instructions have the right to be processed by the processor.
Cache storage is a tiny amount the high performance ram (Random access Memory) that is developed into the processor. This ram stores data which has actually been repeatedly provided by the processor and also it walk not call for a request from the system memory. This form of data is vital to the quick processing of video editing games and 3D applications. Utilizing this type of storage will rise the speed of processing the data.
This word length is the word size of a CPU . This is the variety of bits a CPU can process simultaneously. For instance a 32-bit processor is much faster than a 16 little processor because it has a broader word length. A typical computer system word length is normally between 32 and 64 bits.
The 8088 processor has a clock speed of 4.77 MHz and has one 8-bit indigenous length.The 80486 has a clock speed of 50 to 80 MHz and has a word size of 32 bits.The Pentium 4 together a clock rate of 1.5 gigahertz to 3.2 gigahertz and also has a word length of 64 bits.
The attend to bus broad is the broad of the attend to bus and also determines the maximum quantity of addressable locations. For instance if you have an deal with bus that 8 bits, this way that you have the right to have 256 addresses. This addresses or memory areas will it is in numbered 0 to 255.

The Data bus width is the number of bits that deserve to be transferred simultaneously from one maker to another. Usually the data bus is the exact same size together the deal with bus but not always. If the data bus is 16 bits and also the attend to bus is 32 bits, therefore the data is fetched in 2 x 16 little groups.
