The faster your processor speed, the faster your computer will move, and, all things being equal, the more it will cost. However, given the high speed of modern processors, it's possible to buy one that is faster than you need. On the other hand, there are other ways to speed up a computer that can have a more meaningful impact than CPU speed.
When you see a processor's speed in GHz, it refers to the speed of the processor's internal clock. Every time that the clock ticks, the processor can execute an instruction or read and write data. Internal clock speeds don't tell you how fast the processor can communicate with the outside world.
That is defined by its external clock speed or bus speed, which is usually much slower. This means that if you can't get enough data into the processor to keep it busy until it can communicate with the outside world again, it'll sit idle. This can cause a significant decrease in speed, or sometimes the total blocking of the WiFi signal. The 5 GHz band is much less congested, which means you will likely get more stable connections and witness higher speeds.
The longer waves used by the 2. The shorter waves used by the 5 GHz band makes it less able to penetrate walls and solid objects. As always in life, it depends. Mostly 5 GHz router is more perspective choice, but sometimes changing from one version to another may turn out useless if we cannot use it fully. If we live in place where there are few other networks, and our Internet connection is less than Mbps, we can think about a 2.
On the other hand, if we have a very fast Internet connection and we live in a place where there are many networks, then we should invest in a 5GHz router to escape from crowded 2.

However, the processor's speed rating is just one of many factors that impact how fast it actually processes data. Given that some specialized applications can be very computationally demanding, choosing the fastest computer is more important than buying a machine with the highest clock speed.
Processors work according to a clock that beats a set number of times per second, usually measured in gigahertz. For instance, a 3. Each clock beat represents an opportunity for the processor to manipulate a number of bits equivalent to its capacity -- bit processors can work on 64 bits at a time, while bit processors work on 32 bits at a time.
The clock that usually gets included in marketing materials is the internal clock, but a processor also has an external clock that determines how quickly the processor can communicate with the outside world. The internal clock represents how quickly the processor can manipulate the data it already has, while the external clock specifies how quickly it can read the information it needs to manipulate or how quickly it can output the manipulated data.
As of the date of publication, external clocks are frequently significantly slower than internal clocks. For example, while a processor may run at 3 GHz, its external clock could be anywhere from a few hundred MHz to 1 GHz. Since the external clock determines how quickly the processor can communicate with the system's memory, it has a significant effect on your processor's real-world speed.
