In our series of CPU Gaming Performance articles, we're today having a closer look at two mid-range Intel CPUs. We ran a set of benchmarks as well as even more games on a Core i5-4670K as well as on a Core i5-2500K. In the end we wanted to find out how big the difference between a Haswell quad core and a Sandy Bridge quad core part is. We also overclocked both CPUs to 4.5 GHz and in this regard it was really interesting to see by what margin power consumption went up with both these CPUs.
