Intel Core i5-10400 vs Intel Core i7-4790K

Core i5-10400 vs Core i7-4790K comparison

Our benchmark analysis concludes that the Core i5-10400 performs better than the Core i7-4790K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-4790K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-10400 has significantly more cores than the Core i7-4790K. Indeed, the Core i5-10400 has 6 cores compared to 4 cores found in the Core i7-4790K. It also has more threads than the Core i7-4790K. Our comparison shows that the Core i7-4790K has a slightly higher clock speed compared to the Core i5-10400. Also, the Core i7-4790K has a slightly higher turbo speed. A Core i5-10400 CPU outputs less heat than a Core i7-4790K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-10400 has more threads than cores. Each physical core is split into multiple threads.
