Intel Core i5-8300H vs Intel Core i5-8400H

Core i5-8300H vs Core i5-8400H specs and performance

According to the hardwareDB Benchmark tool, the Core i5-8400H is faster than the Core i5-8300H. Despite this, the Core i5-8300H has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-8400H has a slightly higher clock speed compared to the Core i5-8300H. Also, the Core i5-8400H 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. 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 i5-8300H has more threads than cores. Each physical core is split into multiple threads.
