Intel Core i5-12400F vs Intel Core i7-7820X

Core i5-12400F vs Core i7-7820X comparison

In our benchmarks, the Core i5-12400F beats the Core i7-7820X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7820X in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-7820X has slightly more cores than the Core i5-12400F. Indeed, the Core i7-7820X has 8 cores compared to 6 cores found in the Core i5-12400F. It also has more threads than the Core i5-12400F. These CPUs have different clock speeds. Indeed, the Core i7-7820X has a significantly higher clock speed compared to the Core i5-12400F. Despite this, the Core i5-12400F has a slightly higher turbo speed. A Core i5-12400F CPU outputs less heat than a Core i7-7820X CPU because of its significantly 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 i5-12400F has more threads than cores. Each physical core is split into multiple threads.
