Question: what is difference between core i3 and i7?
Answer: A Core i3 with Hyper-Threading can process two threads per core which means a total of four threads can run simultaneously. ... i7 processors do have it, so can process eight threads at once. Combine that with 8MB of cache and Turbo Boost (below), and you can see why Core i7 chips are more powerful than an i5 or i3.
