Core i7-9700K vs Core i5-12450H benchmarks

Our benchmark analysis concludes that the Core i7-9700K performs better than the Core i5-12450H. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-12450H in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i5-12450H has more threads. Our comparison shows that the Core i7-9700K has a significantly higher clock speed compared to the Core i5-12450H. Also, the Core i7-9700K has a slightly higher turbo speed. The Core i5-12450H outputs less heat than Core i7-9700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache and L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
