Intel Core i7-8750H vs Intel Core i5-8400

Core i7-8750H vs Core i5-8400 comparison

Our benchmark analysis concludes that the Core i5-8400 performs better than the Core i7-8750H. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8750H in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-8750H has more threads. These CPUs have different clock speeds. Indeed, the Core i5-8400 has a slightly higher clock speed compared to the Core i7-8750H. Despite this, the Core i7-8750H has a slightly higher turbo speed. A Core i7-8750H CPU outputs less heat than a Core i5-8400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache and 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 i7-8750H has more threads than cores. Each physical core is split into multiple threads.
