Core i7-8750H vs Core i7-1255U specs and performance
Our benchmark analysis concludes that the Core i7-1255U performs better than the Core i7-8750H. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8750H in all gaming tests too.
In terms of the number of cores of each of these CPUs, the Core i7-1255U has significantly more cores than the Core i7-8750H. Indeed, the Core i7-1255U has 10 cores compared to 6 cores found in the Core i7-8750H. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-8750H has a slightly higher clock speed compared to the Core i7-1255U. Despite this, the Core i7-1255U has a slightly higher turbo speed. The Core i7-1255U outputs less heat than Core i7-8750H 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 i7-8750H. The Core i7-1255U also has slightly 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. Indeed, the Core i7-8750H has more threads than cores. Each physical core is split into multiple threads.
