Core i5-6600K vs Core i7 X 980 benchmarks

According to the hardwareDB Benchmark tool, the Core i7 X 980 is faster than the Core i5-6600K. Despite this, the Core i5-6600K has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7 X 980 has significantly more cores than the Core i5-6600K. Indeed, the Core i7 X 980 has 6 cores compared to 4 cores found in the Core i5-6600K. It also has more threads than the Core i5-6600K. These CPUs have different clock speeds. Indeed, the Core i5-6600K has a slightly higher clock speed compared to the Core i7 X 980. The cache sizes of these CPUs are different. Indeed, the Core i7 X 980 has significantly more L2 cache than the Core i5-6600K

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. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
