Intel Core i5-10400 vs Intel Core i7-10875H

Core i5-10400 vs Core i7-10875H comparison

Our benchmark analysis concludes that the Core i5-10400 performs better than the Core i7-10875H. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-10875H in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-10875H has slightly more cores than the Core i5-10400. Indeed, the Core i7-10875H has 8 cores compared to 6 cores found in the Core i5-10400. It also has more threads than the Core i5-10400. With our hardware info, we find that the Core i5-10400 has a slightly higher clock speed than the Core i7-10875H. Despite this, the Core i7-10875H has a slightly higher turbo speed. The Core i7-10875H outputs less heat than Core i5-10400 thanks to a significantly lower TDP. 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 i7-10875H has slightly more L2 cache than the Core i5-10400. However, both these chips have the same amount of L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i5-10400 has more threads than cores. Each physical core is split into multiple threads.
