I am working on an older office PC for someone that wants to turn it into an inexpensive gaming PC. It has an i5-7400 processor. I went to Tom's CPU Hierarchy Chart to get an idea where the old quad core falls in comparison to today's CPUs. It's actually listed twice (?); once above the Ryzen 7 1700X/Ryzen 5 1600AF... and again below the Ryzen 5 1600/Ryzen 3 3400g. Am I correct in assuming the top slot is a mistake? (Even the lower slot seems a bit high, but a little more believable.) Thoughts?
