Regarding this, is i5 or i7 better?
What's the difference between the Intel Core i5 vs Core i7? You might think it's the number of cores, but for the most part desktop Core i5 processors have four cores, just like i7s. Intel Core i7 processors generally have faster base clock speeds, or in other words they have more Ghz.
Secondly, how much better is the i7 processor than the i5? The difference: Each of the processors has a slightly different boost clock speed, starting at 4.0GHz with the i5-1130G7 and topping out at 4.8GHz with the i7-1185G7. As with desktop chips, Core i7 CPUs tend to be a lot more expensive.
Thereof, will I notice the difference between i5 and i7?
i5-U and i7-U CPUs differ little in performance, as the only differences are a slightly increased cache size and slightly higher frequencies. For so-called standard voltage CPUs, which may have a TDP of around 35W to 45W, the difference is more significant.
Do I need i5 or i7 for gaming?
Answer: Intel Core i5 is more than enough for mid-range systems. Only get an Intel Core i7 for high-end systems with SLI GPU configurations. If you are building a mid-range or a more powerful high-end gaming PC, then you might face a dilemma when it is time to choose the CPU.
