Core i7-8700K Review: Coffee Lake Brews A Great Gaming CPU

Civilization VI, Battlefield 1 & Dawn of War III

Civilization VI AI Test

Our Civilization VI AI test measures performance in a turn-based strategy game, and it tends to favor high frequencies and physical cores.

The -8700K's Turbo Boost frequencies yield surprisingly good results. At stock settings, the processor essentially ties Core i7-7700K, but leads a little more definitively after tuning.

Core i5-7600K fares respectably in Civilization VI at its stock settings. But after a 5 GHz overclock, it yields a 15.1-second result (not pictured) that even beats Intel's fastest CPUs.

The Ryzen processors are much more competitive during Civilization VI's graphics test, but Intel's overclocking headroom proves insurmountable. Compared to Core i7-7700K, the -8700K offers 3.9% more performance in stock form, and a 3% advantage after tuning. Those slim leads mean there is still good value in a Kaby Lake-based platform, particularly in light of the higher price on Coffee Lake K-series SKUs.

A graphics bottleneck limits the frame rates of our Battlefield 1 benchmark, so with the exception of Ryzen 5 1600X and Core i5-7600K, the differences between models are slight.

Intel's Core i7 processors lead. More specifically, though, the -8700K does beat its predecessor.

It’s easy to see the workload's more threaded nature during its opening phase, where a quad-core Core i5-7600K trails the test pool.

Dawn of War III scales well on CPUs with more execution resources. Naturally, then, the Core i7-8700K dominates in stock and overclocked trim.

The Core i7-7800X posts another surprisingly low score. Considering the costs associated with Intel's premium X299 platform, Skylake-X generally doesn't make much sense for gaming.

    Looks like it might be time for AMD to lower prices.

    AMD really has shaken Intel up, never would I have dreamed (before this year) I'd see Intels best gaming cpu (especially a K model) release at $360.

    AMD's price per core is still very strong. It struggles in gaming at 1080p but Tomshardware didn't provide data in 1440p or 4K.

    I'm not yet convinced that AMD is in trouble.

    Hmmm is it worth a skylake 6700K that's stable at 4.6 Overclock to upgrade? Probably not. I wouldn't mind 6 cores though. I wonder how many will hit 5.0!

    8700k is $480ca got the R5 1600 for $255ca and mobo for $120ca. $375 all together and more then happy with the gaming results. But the 8700k dose look sweet on the benchmarks. AMD with a price drop will still sell well

    Of course, while Intel's accelerated Coffee Lake-S launch makes it look today's unveiling is a direct response to heated competition, in reality, the long incubation period for new processors means it’s more likely the result of 10nm manufacturing delays.

    Ummm... Yeah, the design may have been kicking around, and ready to go before Ryzen, but when it is released months earlier than scheduled.... Saying that it wasn't a response to Ryzen seems more like misinformation more than pure fact. Yeah, I don't doubt 10nm manufacturing delays played a part in the previous release date, but Ryzen forced its release a little earlier than planned.

    To AMD fanbois who claimed that Intel was toast and couldn't respond to Ryzen's release, here's Intel's Mic drop. *thud*

    For the rest of us consumers, this is great news for continued strong competition at reduced prices from both companies. :)

    Nearly 90 degrees Celsius when overclocked gaming on an AiO. Prettttttty toasty!

    Z370 motherboards are expensive though...sheesh. And you gotta reach out to liquid cooling companies for attachments for mounting to this socket. Canon Lake may be out before you can get everything situated for a nice 8700k upgrade lmao.

    The reason is simple:
    The built-in frying fat between IHS and die :)

    I don't know if I would call 90C+ on a chiller cooler (granted its a high overclock but the 7700k had the same problem) a mic drop but it is definitely a step in the right direction. If they can get their temperatures under control in the next generation they will win my vote back.
