Intel Core i5-6400 vs Intel Core i7-3770

Core i5-6400 vs Core i7-3770 comparison

According to the hardwareDB Benchmark tool, the Core i7-3770 is faster than the Core i5-6400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-3770 has more threads. Our comparison shows that the Core i7-3770 has a slightly higher clock speed compared to the Core i5-6400. Also, the Core i7-3770 has a slightly higher turbo speed. A Core i5-6400 CPU outputs less heat than a Core i7-3770 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i7-3770 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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
