Civilization VI Graphics & AI, Dawn of War III
Civilization VI AI Test
Civilization's AI test measures performance in a turn-based strategy game and tends to favor per-core performance.
In our Core i7-8700K review, we pointed out that Intel's vanilla -8700 often outperformed the flagship -8700K in our gaming benchmarks. Obviously, those results were difficult to explain, given each CPU's specifications. But the issue persisted for several months (and many motherboard firmware updates). Intel and its motherboard partners have been unable to explain this phenomenon. However, we did notice that it was resolved around the time updates went out for our Spectre/Meltdown patch testing. We still saw a few scattered cases of Core i7-8700 beating the flagship K-series chip, but they're typically results that fall within a margin of error.
Our Civilization VI AI test results are a perfect example. The Core i7-8700 with Corsair's cooler slipped past the Core i7-8700K, but just barely. More important is that you can get -8700K-class performance from the locked model if you don't plan on overclocking.
Civilization VI Graphics Test
The Civilization VI graphics test shows Intel's Core i7-8700 beating the -8700K by a larger margin. In fact, strong performance put the -8700 on equal footing with a tuned Ryzen 7 2700X, and within striking distance of the overclocked Core i7-8700K.
Separately, we saw the Core i7-7700K about 6 FPS ahead of the -7700. This illustrates the bigger gap between Intel's previous-gen locked and K-series models, attributable to large differences in base and Turbo Boost frequencies.
Warhammer 40,000: Dawn of War III
Core i7-8700 almost kept up with the stock -8700K. But tuning Intel's flagship Coffee Lake-based CPU solidified its lead.
