The megahertz, abbreviated MHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one million hertz (1,000,000 Hz). The megahertz is commonly used to express microprocessor clock speed.
Hereof, what is the difference between the megahertz and gigahertz?
Differences between the two: One GHz equals one billion cycles per second whereas one MHz equals one million cycles per second. GHz is used to study the electromagnetic spectrum other than computing and radio transmission.
What is the best GHz?
It depends on how well the chip's single threaded performance is. For example, a 3.5 GHz Intel i7 quad core performs better in most games than a 4.0 GHz 8-core AMD, because it has better single-thread performance. It really depends between which two you are picking between.
What is GHz in frequency?
A band of frequencies clustered around 2.4 GHz has been designated, along with a handful of others, as the Industrial, Scientific, and Medical radio bands. "A lot of the unlicensed stuff — for example, Wi-Fi — is on the 2.4-GHz or the 900-Mhz frequencies, the ISM bands.
