Core i3 The Intel Core i3 processors feature the most versatility when it comes to choosing the ideal processor if you’re on a budget. The i3 models are some of the most inexpensive ones, meaning they are the least powerful of the rest on this list. All i3 Intel Core processors can be found with either 2 or 4 cores. This is usually known as a dual-core processor with decent amounts of power and a relatively low price. Intel Core i3 11-Gen series is out now and all of the models feature either 2 or 4 cores with 6MB and 8MB of Intel Smart Cache.
