Intel Core i7-8700 vs Intel Core i5-9400F

Core i7-8700 vs Core i5-9400F benchmarks

Our benchmark analysis concludes that the Core i7-8700 performs better than the Core i5-9400F. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8700 has more threads. Our comparison shows that the Core i7-8700 has a slightly higher clock speed compared to the Core i5-9400F. Also, the Core i7-8700 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 i7-8700 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. Indeed, the Core i7-8700 has more threads than cores. Each physical core is split into multiple threads.
