Intel Core i5-7400 vs Intel Core i7-4770K

Core i5-7400 vs Core i7-4770K specs and performance

According to the hardwareDB Benchmark tool, the Core i7-4770K is faster than the Core i5-7400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7400 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-4770K has more threads. With our hardware info, we find that the Core i7-4770K has a slightly higher clock speed than the Core i5-7400. Also, the Core i7-4770K has a slightly higher turbo speed. A Core i5-7400 CPU outputs less heat than a Core i7-4770K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Core i7-4770K also has slightly more L3 cache.

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