Intel Core i5-8400 vs Intel Core i3-3220

Core i5-8400 vs Core i3-3220 specs and performance

Our benchmark analysis concludes that the Core i5-8400 performs better than the Core i3-3220. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-3220 in all gaming tests too.

With info from our database, we find that the Core i5-8400 has significantly more cores with 6 cores whereas the Core i3-3220 has 2 cores. It also has more threads than the Core i3-3220. These CPUs have different clock speeds. Indeed, the Core i3-3220 has a slightly higher clock speed compared to the Core i5-8400. The Core i3-3220 outputs less heat than Core i5-8400 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
