Question: what is the difference between core i5 and core i7?
Answer: 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. ... A higher number means better performance, as the i5-6500 is faster than the i5-6400.
