Intel Core i7-5930K vs Intel Core i7-1255U

Core i7-5930K vs Core i7-1255U benchmarks

Our benchmark analysis concludes that the Core i7-1255U performs better than the Core i7-5930K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-5930K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-1255U has significantly more cores with 10 cores compared to the Core i7-5930K that has 6 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-5930K has a significantly 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 i7-5930K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. Indeed, the Core i7-5930K has more threads than cores. Each physical core is split into multiple threads.
