Question: what is the difference in speed between i5 and 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.
