Intel Core i3-8350K vs Intel Core i5-8400H

Core i3-8350K vs Core i5-8400H specs and performance

Our benchmark analysis concludes that the Core i5-8400H performs better than the Core i3-8350K. Despite this, the Core i3-8350K has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i5-8400H has more threads. Our comparison shows that the Core i3-8350K has a significantly higher clock speed compared to the Core i5-8400H. The Core i5-8400H outputs less heat than Core i3-8350K thanks to a significantly lower TDP. 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 i5-8400H also has significantly 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. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
