Honestly it depends on the specific CPU. Most i5 7th gens are shit and only have 4cores/4threads. Some i7 7th gens are soo bad. The best i5 7th gen is probs i5 7400/7500 and the best i7 7th gen is i7 7700 with 4cores and 7threads. BUT trust me: you are way better of going with an i3 8100 or an i5 8400 for locked cpus. Also, research the specs of the cpu. Give me your country reigion and budget so I can help you search
