Indeed, the Core i7-12800H has 14 cores compared to 8 cores found in the Core i7-9700K. It also has more threads than the Core i7-9700K. With our hardware info, we find that the Core i7-9700K has a significantly higher clock speed than the Core i7-12800H. Also, the Core i7-9700K has a slightly higher turbo speed. The Core i7-12800H 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. The info from our database shows that the Core i7-12800H has more L2 cache than the Core i7-9700K. The Core i7-12800H also has significantly more L3 cache.

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. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
