Core i9-11900K vs Core i7-12800HX benchmarks

Our benchmark analysis concludes that the Core i7-12800HX performs better than the Core i9-11900K. Despite this, the Core i9-11900K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-12800HX has significantly more cores with 16 cores compared to the Core i9-11900K that has 8 cores. It also has more threads than the Core i9-11900K. Our comparison shows that the Core i9-11900K has a significantly higher clock speed compared to the Core i7-12800HX. Also, the Core i9-11900K has a slightly higher turbo speed. The Core i7-12800HX outputs less heat than Core i9-11900K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Core i7-12800HX also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i9-11900K has more threads than cores. Each physical core is split into multiple threads.
