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.
The difference between a processor's internal and external clock speeds is one limitation on its performance. Another is the number of clock ticks it takes to execute an instruction. While some instructions can be completed in one clock tick, it could, for instance, take four ticks to complete a multiplication operation.
A nanosecond is a billionth of a second. Some processors can run at 5 GHz. Intel Core i7 processors generally have faster base clock speeds, or in other words they have more Ghz. Generally, the next generation of laptops is always considered better than the previous generation appliances. Thus, it is evident that the 10th gen i5 laptop should be better than the 8th gen model. The only point of difference between both these laptops is the processor.
So i5 is just not good for the price we are paying. Also, keep in mind ti is capable but not at all future proof. So the minimum requirement in should be RTX Horizon Zero Dawn is an example of a title that really loves extra cores and threads.
For gaming, you want higher single core clock speed with a good GPU and not a heavy multi-core processor with is slow. A faster i5 is better than a slower i7. To answer your question directly, the i5 is absolutely fine for gaming. 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. Clock speeds also don't tell you how long it takes a processor to actually do something.
