Intel Core i5-9400 vs Intel Core i7-11390H

Core i5-9400 vs Core i7-11390H specs and performance

According to the hardwareDB Benchmark tool, the Core i5-9400 is faster than the Core i7-11390H. Despite this, the Core i7-11390H has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i5-9400 has significantly more cores than the Core i7-11390H. Indeed, the Core i5-9400 has 6 cores compared to 4 cores found in the Core i7-11390H. Despite this, the Core i7-11390H has more threads than the Core i5-9400. The Core i7-11390H outputs less heat than Core i5-9400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. For instance, the Core i5-9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
