Core i9-7900X vs Core i7-12800HX comparison

According to the hardwareDB Benchmark tool, the Core i9-7900X is faster than the Core i7-12800HX. Despite this, the Core i7-12800HX has the advantage in our gaming benchmark.

With info from our database, we find that the Core i7-12800HX has significantly more cores with 16 cores whereas the Core i9-7900X has 10 cores. It also has more threads than the Core i9-7900X. With our hardware info, we find that the Core i9-7900X has a significantly higher clock speed than the Core i7-12800HX. Despite this, the Core i7-12800HX has a slightly higher turbo speed. The Core i7-12800HX outputs less heat than Core i9-7900X 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 i9-7900X has more threads than cores. Each physical core is split into multiple threads.
