Also question is, how many GHz is a core?

A core is a single processing unit, multi-core processors have multiple processing units. So a dual-core 3.0GHz processor has two processing units each with a clock speed of 3.0GHz. A six-core 3.0GHz processor has six processing units each with a clock speed of 3.0GHz.

Subsequently, question is, are 4 cores better than 2? It's a little more complicated than that. More cores are faster only if a program can split its tasks between the cores. A newer dual core CPU with a higher clock speed will often outperform an older quad core CPU with a lower clock speed.

Thereof, is it better to have more cores or higher GHz?

Clock speeds are measured in gigahertz (GHz), with a higher number equating to higher clock speed. Multi-core processors were developed to help CPUs run faster as it became more difficult to increase clock speed.

Is 1.6 GHz good?

Once, a higher number meant a faster processor, but advances in technology have made the processor chip more efficient so now they do more with less. The i series 1.6 GHz CPU runs faster and outperforms the old style Pentium 4 CPU.
