what is Ghz?

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

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...

its Gegahertz its the speed of the pc I dont tknk pentium 3 can has 3.00 ghz happy lottin and have a nice day

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

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

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
