Intel Core i5-10400 vs Intel Core i5-9400F

Core i5-10400 vs Core i5-9400F benchmarks

In our benchmarks, the Core i5-10400 beats the Core i5-9400F in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i5-10400 has more threads. In terms of clock speed, the Core i5-10400 and Core i5-9400F are identical in this regard. Despite this, the Core i5-10400 has a slightly higher turbo speed. 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i5-10400 also has slightly more L3 cache.

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. Indeed, the Core i5-10400 has more threads than cores. Each physical core is split into multiple threads.
