From the many benchmarks and reviews I've encountered, this doesn't seem to hold up. When it comes to value for money, the 8400 and then the i5 8600K clearly offer substantial improvements. Still, in raw performance, the i7 7700K remains ahead of the fully locked Coffee Lake i5s in most scenarios, particularly under heavy multi-threaded tasks and when boosted. That said, at the top end it sits in the 5-10 percent range, which is impressive. My i7 6700K runs a bit slower at stock speeds compared to the i5 8600K, but it edges ahead of the i5 8400. At around 4.7GHz, it slightly surpasses the stock 8600K. When boosted to that level, it edges out the 7700K by roughly a similar margin—perhaps around 10 percent, maybe even a touch more at about 15 percent. I’d argue that a 4c/8t setup performs much better than a 6c/6t in most tests.
