What is processor speed?

Question

I want to buy a laptop but I am concerned about processor speed. What is it? What do I need to know?

Thanks

Answer 1

it is the speed of the cpu, or processor...basically, the faster the processor, the faster the computer, as long as you have a decent amount of ram

Answer 2

The processor speed tells how many instructions the processor executes in a second. The higher the number, the faster it is.

Other factors affect actual processor throughput: the type of chip it is (Celerons, for example, are less capable than a Pentium operating at the same speed, because of the internal architecture of the 2 chips) and on board cache memory (the more, the better) are two.

Other factors determine how fast the computer is in performing real-world applications (i.e., the speed you "feel"): The type and speed of the bus (which carries the communications between the processor, the external memory, the hard disk, and other peripheral devices), the video processor specs, the screen specs to a certain extent, the hard disk type and rotation speed, the amount, type, and speed of the RAM, and the software you run all determine how speedily your laptop will operate. The processor speed is not the most important factor unless you are looking at something really low-end.

Answer 3

The speed that the processor can run at is a function of many different factors. Some of these are related to design of the processor itself, which dictates the internal timing requirements that limit the maximum speed the processor can handle. Manufacturing factors relate to the process technology used, circuit size, die size and process quality.

In general, the smaller the chip, the faster it can run. This is due in part to reduced power consumption and heat generation; heat is generated when transistors switch from a zero to a one or vice-versa, and the faster the chip runs, the more switching in a given unit of time, so the more heat that is produced. A chip that overheats locks up or causes computation errors. Designers move chips to smaller circuit sizes to keep heat down as they ratchet up CPU speed.

In addition, there are manufacturing variabilities that allow some chips to run faster than others even though they were produced with the same process and even with the same wafer. This is called speed rating and is done during testing.

Answer 4

Processor speed is the speed at which the computer can process information...everything the computer does needs processed and so it passes through the processor. The faster, the better.

Answer 5

The processor runs off a clock. This sets the pace at which the processor can do things like access memory, add/subtract, make decisions.

It is tough to compare processor speeds between differnt types. An AMD 2.2GHz runs differently than a Pentium IV 2.2GHz, so you can't just compare their clock rates to know which is faster.

Answer 6

it depends upon the budget , latest and the most talked about processor is the centrino duo 2, which is fastest available. just dont get any of those pentium mobiles. try centrino mobile processors, they are good. all brands offer them

Answer 7

Ghz Is how fast your computer is. It would be in the my computer folder then you click to view system info. It should be labeled 1Ghz, 2Ghz. For my opinion 2Ghz is plenty fast enough for a laptop.

Answer 8

its mesured in Hertz Hz .. it means how many frequency ur proccesor can do in a period of time ..
the higher ... the faster.... the better ..

Answer 9

it's how fast your computer takes to process a task
