Intel Core i5-6400 vs Intel Core i7-4900MQ

Core i5-6400 vs Core i7-4900MQ specs and performance

According to the hardwareDB Benchmark tool, the Core i7-4900MQ is faster than the Core i5-6400. Despite this, the Core i5-6400 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-4900MQ has more threads. These CPUs have different clock speeds. Indeed, the Core i7-4900MQ has a slightly higher clock speed compared to the Core i5-6400. Also, the Core i7-4900MQ has a slightly higher turbo speed. The Core i7-4900MQ outputs less heat than Core i5-6400 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i7-4900MQ also has slightly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
