Core i9-7940X vs Core i7-12800H comparison

Our benchmark analysis concludes that the Core i9-7940X performs better than the Core i7-12800H. Despite this, the Core i7-12800H has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i9-7940X has more threads. Our comparison shows that the Core i9-7940X has a slightly higher clock speed compared to the Core i7-12800H. Despite this, the Core i7-12800H has a slightly higher turbo speed. The Core i7-12800H outputs less heat than Core i9-7940X thanks to a 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 i9-7940X has more threads than cores. Each physical core is split into multiple threads.
