Core i7-6850K vs Core i5-1235U comparison

According to the hardwareDB Benchmark tool, the Core i7-6850K is faster than the Core i5-1235U. Despite this, the Core i5-1235U has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i5-1235U has significantly more cores than the Core i7-6850K. Indeed, the Core i5-1235U has 10 cores compared to 6 cores found in the Core i7-6850K. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-6850K has a significantly higher clock speed compared to the Core i5-1235U. Despite this, the Core i5-1235U has a slightly higher turbo speed. The Core i5-1235U outputs less heat than Core i7-6850K 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 i5-1235U has significantly more L2 cache than the Core i7-6850K. Despite this, the Core i7-6850K has slightly more L3 cache compared to the Core i5-1235U.

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 i7-6850K has more threads than cores. Each physical core is split into multiple threads.
