How many cores does an i7 have?
Most of the latest Intel Core i5 and Core i7 CPUs have four or more cores, which is what we consider the sweet spot for most mainstream users. Many late-model desktop Core i5 and Core i7 chips have six cores, and a few ultra-high-end gaming PCs come with eight-core Core i7s.
How do I know if my CPU is bad?

How can a single core processor run multiple tasks at once?

Multitasking on a multiple-processor system still involves the processors switching between tasks because there are almost always more tasks to run than there are processors.
