Is i5 4th gen better than i3 5th gen?
The i3 has 2 physical cores, hyperthreading, and turbo boost. Without question the i5 is better. On top of that Broadwell (5th gen) is just a die shrink of Haswell (4th gen). So unless you’re going to use the integrated GPU extensively, there is virtually no performance difference between the two generations.
Is a 4th gen i3 better than a 3rd gen i5?
As others have said, i5 3rd gen is stronger than i3 4th gen. Of course, an i3 4th gen CPU will allow you to get a motherboard that’ll last longer before going obsolete.
Which is better Core i3 6th gen or Core i5 4th gen?
Any 4th Gen I5 will cost more than any 6th Gen I3 you buy, but the I5 overall will have better multi-threaded performance but most I3s have a higher stock frequency and some higher instructions-per-clock for better single-core performance. As for motherboard, if getting an I5-4690K, a Z97.
Which is better i3 5th gen or i5 2nd gen?
The differences are that the i3 is a duo core cpu with hyperthreading which makes up 4 logical cores, while the i5 has 4 physical core without hyperthreading, the newer i3 will have better single core performance to close some of the gap in performance but the i5 in my books is still the more powerful cpu.
