Core i7-12700H vs Core i9-9940X comparison

In our benchmarks, the Core i7-12700H beats the Core i9-9940X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9940X in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i9-9940X has more threads. Our comparison shows that the Core i9-9940X has a significantly higher clock speed compared to the Core i7-12700H. Despite this, the Core i7-12700H has a slightly higher turbo speed. A Core i7-12700H CPU outputs less heat than a Core i9-9940X 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 i7-12700H has more threads than cores. Each physical core is split into multiple threads.
