New benchmarks suggest that the i7-8700K and i5-8400K may provide a 32 percent increase in performance over previous chips, such as the i7-7700K and i5-7600K. While these are synthetic benchmarks, the author notes that SiSoftware Sandra has been a good indicator of real-world performance.
Collectively, we are looking at around a 32.4 percent jump in performance. We also see that Intel's claimed performance figures are not too far off. That is encouraging, especially if you have been holding off on upgrading in hopes that Coffee Lake would bring enough of a boost over whatever architecture you are currently running. Moving onto to the Core i5-8400K, this one has the distinction of being the first-ever Core i5 chip with 6 physical cores. It does not support Hyper Threading, so we are looking at 6 cores/threads of processing.
