Intel Core i3-10300 vs Intel Core i5-9400

Core i3-10300 vs Core i5-9400 comparison

Our benchmark analysis concludes that the Core i5-9400 performs better than the Core i3-10300. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-10300 in all gaming tests too.

With info from our database, we find that the Core i5-9400 has significantly more cores with 6 cores whereas the Core i3-10300 has 4 cores. Despite this, the Core i3-10300 has more threads than the Core i5-9400. These CPUs have different clock speeds. Indeed, the Core i3-10300 has a slightly higher clock speed compared to the Core i5-9400. Also, the Core i3-10300 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. The cache sizes of these CPUs are different. Indeed, the Core i5-9400 has significantly more L2 cache than the Core i3-10300. The Core i5-9400 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 i3-10300 has more threads than cores. Each physical core is split into multiple threads.
