Intel Core i5-6400 vs Intel Core i5-6440HQ

Core i5-6400 vs Core i5-6440HQ specs and performance

According to the hardwareDB Benchmark tool, the Core i5-6400 is faster than the Core i5-6440HQ. Despite this, the Core i5-6440HQ has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-6400 has a slightly higher clock speed compared to the Core i5-6440HQ. Despite this, the Core i5-6440HQ has a slightly higher turbo speed. The Core i5-6440HQ outputs less heat than Core i5-6400 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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
