What Do Gigahertz Do?

Gigahertz is often used to measure central processing unit (CPU) clock speed. In general, higher CPU clock speeds indicate faster computers. That being said, speed-impacting factors include pipeline depth, instruction sets, internal cache, network/bus speed, disk performance and software design.

Is higher GHz better?

The higher the clock speed, the faster the car (system) will go. Clock speed is measured in GHz (gigahertz), a higher number means a faster clock speed.

Is a 2.3 GHz processor good?

2.3GHz is enough, but if the cost is too much for you, then skip out on 2.6. Though the extra boost and upgrade in the Iris Pro may be useful for doing 3D with the integrated card. Compile times should also increase.
