Eli5: How are i5 processors able to compete with i9 processors

1.16K viewsOtherTechnology

I always thought bigger number = better in the terms of pc components. Recently ive learned i5s can compete with i9s. I saw a post one day that said “i could replace your processors with i3’s and almost none of you would even notice”

How does this work?

Compete? Only in the same sense that a Fiat 500 can compete with a Lamborghini in getting from one red light to the other.

It’s not to say that the 500 is in any way equivalent, just that the circumstances make it perfectly adequate for purpose, while the Lamborghini is completely underutilized.

In the same sense, if all a user does is web browsing, taxes and using Office, they wouldn’t even notice if their CPU would get replaced with a lower teir obe, because it’d be perfectly adequate for purpose. If they have a high end CPU, they overpaid.

The other part is how the task behaves. Even an i9 will struggle if the program only uses a single core, because then 95% of the CPUs processing power goes completely unused, with just one core being run ragged. As long as the individual cores are equivalent, an i3 and i9 will do identical work.

But give the PC any computing intensive task that is properly distributed between cores, and the difference is immediate and unmistakable.
