Final Thoughts & Conclusion
This CPU was a bit interesting to test due to its performance level. When compared with mainstream CPU’s of the last few generations, it just mopped the floor with all of them. With many of our benchmarks placing this CPU in line with High-End Desktop CPU’s as far as scores were concerned, it often appears when looking at the charts that this CPU is near the bottom. That is quite obviously not the case, but we decided to compare this CPU more to our high-end charts where it actually placed, rather than out mainstream charts where it should belong.
Some users may be a little miffed by the lack of backward compatibility with motherboards, but the changes Intel made were purposeful and seemed to work quite well. We tested several z370 motherboards, and the VRM’s never even got warm, even while overclocked. The improved memory layouts also made for some greatly increased performance across the board. You won’t be able to use 8th generation CPU’s in your existing 100 and 200 series boards, but you wouldn’t want to anyway.
Overall, If you are looking at building a new affordable gaming machine, you might consider the unlocked i5-8600K for the extra clock speeds but if overclocking isn’t your thing, or you just need a high-performance workstation for productivity reasons, the i5-8400 would be a great choice. 50% more cores and significant performance gains for only a very small increase in price makes this a tough choice to beat and gets our recommendation. Great job Intel!
