Intel Core i5-6400 vs Intel Core i7-4702MQ

Core i5-6400 vs Core i7-4702MQ comparison

In our benchmarks, the Core i5-6400 beats the Core i7-4702MQ in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-4702MQ in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-4702MQ has more threads. These CPUs have different clock speeds. Indeed, the Core i5-6400 has a slightly higher clock speed compared to the Core i7-4702MQ. Also, the Core i5-6400 has a slightly higher turbo speed. The Core i7-4702MQ 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. The cache sizes of these CPUs are different. Indeed, the Core i5-6400 has significantly more L2 cache than the Core i7-4702MQ. However, both these chips have the same amount of 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.
