It’s time to replace your computer. Maybe it was purchased during the last Republican administration, or you ruined it with a spilled drink, or maybe you’ve just got some money to burn and you’d like to blow it on Intel’s new Kaby Lake microarchitecture. Whatever the reason, you’re ready to upgrade your computer, and you’re going to be left with a big choice. Do you spend the extra cash for the categorically faster i7 processor, or do you pinch a few pennies and go with the i5.
After running both processors (the 4.5GHz i7-7700K and the 4.2GHz i5-7600K) through the ringer in a computer that was otherwise the exact same, we can say, without a doubt, that you should save your money. For most people the i7 just isn’t worth it.
