Intel Core i9-10850K vs Intel Core i7-1255U

Core i9-10850K vs Core i7-1255U specs and performance

According to the hardwareDB Benchmark tool, the Core i9-10850K is faster than the Core i7-1255U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-1255U in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i9-10850K has more threads. These CPUs have different clock speeds. Indeed, the Core i9-10850K has a significantly higher clock speed compared to the Core i7-1255U. Also, the Core i9-10850K has a slightly higher turbo speed. The Core i7-1255U outputs less heat than Core i9-10850K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-1255U has significantly more L2 cache than the Core i9-10850K. Despite this, the Core i9-10850K has significantly more L3 cache compared to the Core i7-1255U.

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 i9-10850K has more threads than cores. Each physical core is split into multiple threads.
