Intel Core i5-8400H vs Intel Core i7-10875H

Core i5-8400H vs Core i7-10875H comparison

According to the hardwareDB Benchmark tool, the Core i7-10875H is faster than the Core i5-8400H. Despite this, the Core i5-8400H has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7-10875H has significantly more cores than the Core i5-8400H. Indeed, the Core i7-10875H has 8 cores compared to 4 cores found in the Core i5-8400H. It also has more threads than the Core i5-8400H. With our hardware info, we find that the Core i5-8400H has a slightly higher clock speed than the Core i7-10875H. Despite this, the Core i7-10875H 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, the Core i7-10875H has significantly more L2 cache when compared to the Core i5-8400H. 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 i5-8400H has more threads than cores. Each physical core is split into multiple threads.
