I don't know actually what it mean in computer speed.For example Pentium 3 processor have 3.00Ghz and AMD have 2.Ghz someone says that both of these speed are same.How it happens? If you have any idea please help me out because I am in a big confusion.

Hey there How2Do, I am a Programmer and not really familiar with the hardware stuff but to me, the more GHZ a computer has, the faster it runs so obviously, 3GHZ would perform better than a 2GHZ and by the way, GHZ is the CPU processing speed. However, even with the lower GHZ, a computer can still run fast depending on how much RAM (Random Access Memory) it has and the more RAM it has the more tasks it can handle and thus, it performs faster. But still, there are other guys who are more of the hardware experts who can give you a better understanding about GHZ. Hope my post helps a little. Cest_moi

Oh you are a programmer anyway thanks this pleasant surprise a programmer posting about hardware stuff.This is good to know everything about something so you could post this comment am I right? I knows the CPU speed now More GHZ performs more power like that now I using 2.4 AMd processor.My friends were using Intel I can't compare my PC with others like intel processors.Thnks...happy My lotting...

You are correct!You have started an interesting post so everyone can learn more aspects about computer as well as myself. BTW, I heard that P5 (Pentium V) will be released sometime in 2010 or something like that, if I am not mistaken, with a CPU clock speed of 10GHZ.

GHZ stands for Giga Hertz.Giga refers to 10 to the power 9 and Hertz is an unit of number of cycles per second(1/sec).Now these speeds you mention refer to the clock speed of the processors...i.e 300000000 clocks( or electrical voltage pulses) per second..is the speed of these processors...So now faster your processor is and faster,the computer can execute the instructions,provided all the other peripherals remain same.Hope this helps you.Good Luck.

The first responses said it very well, but I wanted to add that I haven't seen much of 'mips' these days. Clock speeds are nice and all that, but I remember when mips was a better measure (millions o processes per second). That measured actual processes if I remember right. I wonder if they still use that...

I don't know why it didn't use in market now if it available our calculations will be easy and silly.We have to wait for that as I think in olden may be used but now what happens in clock speed?

With AMD, you don't really measusre by the clock speed. The Front Side Bus is a little better than an Intel chip so a 1.7GHz Amd Athlon XP is actually the equivilant of and Intel P4 at 2.4GHz

Yes this was my question Actually doubted in this case I didn't know how it differ from Intel and Amd performance.Now it is easy to understand but I have a question remaining why it comes difference in its speed calculation?can you say...?

GHz - Gigahertz, commonly used for measuring computer performance and radio frequency, In computer in refers to the clock speed of CPU (Central Processing Unit).

you could go to www.tomshardware.com/ there is an article there that will describe what is cpu performance about -Speed "GHZ" -Front side Bus -L1 and L2 cache -Ram Lantency,Cache Lantency -Over clocking -Multi core CPU and approach Is a long learning curve but is interesting to learn how a computer ticks : D
