Core i9-9940X vs Core i7-12650HX specs and performance

According to the hardwareDB Benchmark tool, the Core i7-12650HX is faster than the Core i9-9940X. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9940X in all gaming tests too.

Our spec comparison shows that they have an identical amount 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 i7-12650HX. Despite this, the Core i7-12650HX has a slightly higher turbo speed. The Core i7-12650HX outputs less heat than Core i9-9940X 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 i9-9940X has more threads than cores. Each physical core is split into multiple threads.
