when buying a laptop what does GHZ mean?

Question

is it better to have 2.4 or 1.8

Answer 1

Laptop or desktop, GHz means the same thing.

First off, Hertz (Hz) means "cycles per second" and is a common way of talking about waveforms in physics and electronics.

The "G" in front means "giga" and that prefix stands for a billion.

The microprocessors in computers are commonly rated by something called their "clock speed," and that is rated in GHz (giga Hertz), and the rating indicates how many instructions per second the chip can manage.

In general, more GHz is better, so you'd want to pick a 2.4 over a 1.8. But whether or not you'll even notice the difference depends on what you're doing with the computer. If you're just doing word processing and simple Internet surfing, you'll never be able to tell the difference. However, other applications require faster processors. For example, if you do any kind of music recording, a fast processor is essential. By "music recording," I'm not talking about changing your CDs to MP3 files to listen to on your portable device, but rather actually using analog/digital convertors to make your laptop into a recording studio. Those kinds of activities do a lot of stuff in short time periods, so you'll often notice problems with slower processors.

But still, all thigns being equal, faster is better if faster fits into your budget.

Hope this helps!

Answer 3

Only a few above point out that "other factors" are involved. It is not as simple as GHz alone. for example, GHz is the "clock speed" , so DO NOT compare clock speed unless they use the same line of processors, such as Intel core i3, i5 or i7. A 3.5 GHz with an i5, would be slower than say a 3.1 GHz with an i7, for example.

It means gigahertz, and is a unit of frequency (billions of pulses per second). As far as computers go, it represents the normal clock frequency of the computer's central microprocessor. A good rule of thumb (with some exceptions) is that the processor with the highest clock frequency is fastest. So given no other information, I would go with the 2.4 GHz processor unless the price difference was dramatic or I was short on money. Good night!

Answer 5

GHZ is gigahertz, a general reference for the speed of the processor. Generally, 2.4 GHZ is faster than 1.8. Go with the 2.4 if you can afford it, but for most applications, the difference isn't all that critical.

Answer 6

GHZ is Gigahertz, its a measure of the speed at which your processor runs (its a bit more complex than that but that pretty much sums it up)

Higher numbers are always better (faster)

Answer 7

For all other factors identical, the 2.4Ghz will process 33% faster.

Of course there are a lot of other factors to consider. The main ones being the CPU internal cache size (Celeron is lowest), number of cores (many newer Intel processors come with 2 integrated processors), the bus speed and the amount of memory.

Answer 9

GHZ basically represent the clock speed of the processor. Like a cars has horsepower, processor has clock speed.

Answer 10

GHz is basically how fast the processor is. So, the more GHz, the faster processor, the faster computer. In other words get the 2.4Ghz
