Intel Core i5-10400 vs Intel Core i9-9880H

Core i5-10400 vs Core i9-9880H specs and performance

Our benchmark analysis concludes that the Core i9-9880H performs better than the Core i5-10400. Despite this, the Core i5-10400 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i9-9880H has slightly more cores than the Core i5-10400. Indeed, the Core i9-9880H has 8 cores compared to 6 cores found in the Core i5-10400. It also has more threads than the Core i5-10400. These CPUs have different clock speeds. Indeed, the Core i5-10400 has a slightly higher clock speed compared to the Core i9-9880H. Despite this, the Core i9-9880H has a slightly higher turbo speed. The Core i9-9880H 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. In terms of cache, the Core i9-9880H has slightly more L2 cache when compared to the Core i5-10400. The Core i9-9880H also has slightly more 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.
