2GHz is better than 1.

@Trisrock

It helps the processsor function all of it's capability faster.

But having a high Gigahertage doesn't mean that the processor is really good. It could simply be a gimmick.

You want cache size, that ranges from 4mb to 15mb.

GHz stands for GigaHertz.
Giga is approximately 1 billion
Hertz stands for ->Cycles per Second

2.0GHz to 2.4GHz is an amount not worth worrying about.

There are other factors to consider now, besides Frequency Rate for a processor. Trying to see how well a processor performs, by it's stated frequency rate, is something left behind by the single core processors.

It was found, that just increasing the frequency rate, would increase the heat given off by the processor. Heat=Wasted Energy. Also causes Electron Migration. Electrons inside the processors circuitry started jumping circuit paths, and caused resistance. Resistance causes heat. The electrons also went to the wrong circuit path, by jumping across. Eventually the processor melted down.

Processors have gone to multiple cores for this reason. Two, three, and four cores, are used now. When you see a stated frequency rate now, it is the rate for EACH core.
For example: Intel Core2 Duo E4500. This processor has TWO processor cores operating at 2.2GHz EACH. Doesn't add up to 4.4GHz. Doesn't work that way. The processor still operates at 2.2GHz. The processor cores 'piggyback' off of each other, and do twice the work in a given time.

Architecture has changed. The architecture size for a processor is stated in -> nm nm stands for NanoMeter.
1 NanoMeter is approximately 1 Billionth of a Meter. Pretty SMALL, huh?
(NOW! They started out in µm. This stands for MicroMeter. 1 Millionth of a meter.

Many processors have gone way down in architecture size. At one time 90nm was the norm. Now 45nm is the norm. Processors are headed towards 22nm before long.

1.Smaller architecture size means smaller circuitry. Less time for electrons to cross. Speeds things up.

2.Also means less heat. Less resistance. Processor runs cooler. Remember Heat=Wasted Energy

3.Smaller circuitry means less power is used.

4.Means more components can be put in a space. (More transistors and related components for the transistors)

Instruction Sets are MUCH more advanced.
Intel is using the SSE4.2
AMD is using the SSE5
(This is why, even though I prefer Intel, I state that AMD's kick booty too!
Intel has an Ad campaign that slams AMD. It even goes so far as to suade reviewers for the AMD processors! Kind of like the MAC and PC 'war' )
Advanced Instruction Sets make the processor More Efficient.

So you can't just judge a processor by it's frequency rate.
And a half gigahertz, is no increase worth writing home to mom about!
