Core i5-7400 vs Core i7-2700K specs and performance

According to the hardwareDB Benchmark tool, the Core i7-2700K is faster than the Core i5-7400. Despite this, the Core i5-7400 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i7-2700K has more threads. Our comparison shows that the Core i7-2700K has a slightly higher clock speed compared to the Core i5-7400. Also, the Core i7-2700K has a slightly higher turbo speed. A Core i5-7400 CPU outputs less heat than a Core i7-2700K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
