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

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Grand Theft Auto V, Hitman & Shadow of Mordor

Grand Theft Auto V

Grand Theft Auto V continues to favor Intel architectures and, more generally, multi-core designs. The Core i7-8700K offers 7.6% more performance than the -7700K at stock settings. This grows to a 11.5% lead after some tuning.

Kaby Lake- and Coffee Lake-based Core i7 processors set themselves apart from the pack during our benchmark, specifically offering a 16-25% performance advantage over the Ryzen models at stock settings.

Hitman (2016)

Core i7-7800X finally shows up in the top half of our chart thanks to its effective architecture and 6C/12T configuration. It's still no match for the -8700K, though, probably due to its more conservative 4 GHz Turbo Boost ceiling.

The new -8700K offers the best performance in stock form, demonstrating a 9 FPS advantage over its nearest competitor. Meanwhile, Core i7-7700K turns the tables with a slight lead after overclocking. Given their similar architectures and manually-defined frequencies, a little variance there is expected. Consider the chips to be tied after tuning.

Middle-earth: Shadow of Mordor

The Core i7-8700K surprisingly falls behind its predecessor at stock settings. We examined each chip's Turbo Boost behavior and discovered that the -8700K ran through at a higher frequency. But, like the -7700K, it doesn’t reach peak frequencies. Rather, it drops to lower clock rates throughout our run.

As mentioned at the outset of our performance testing, we saw higher benchmark numbers from the lower-end Core i7-8700 in several games. Coffee Lake and its Z370 platform are new, so perhaps firmware tuning will iron out some of these issues over time.

    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.
