Intel Core i5-9400F vs Intel Core i3-2120

Core i5-9400F vs Core i3-2120 benchmarks

In our benchmarks, the Core i5-9400F beats the Core i3-2120 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-2120 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-9400F has significantly more cores than the Core i3-2120. Indeed, the Core i5-9400F has 6 cores compared to 2 cores found in the Core i3-2120. It also has more threads than the Core i3-2120. These CPUs have different clock speeds. Indeed, the Core i3-2120 has a slightly higher clock speed compared to the Core i5-9400F. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-9400F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
