Coffee Lake Thread

Despite a few missteps, Core i7-8700K lives up to Intel’s claims. While it doesn't beat the -7700K by a massive margin, the Coffee Lake flagship does deliver better performance in stock and overclocked form. Of course, adding a Z370 motherboard and competent cooler knocks you over the $400 mark, so be ready to pay for that privilege.

Value-seekers have to be asking if Core i7-8700K's price tag is even worth paying, then. After all, you can get Ryzen 7 1800X-class performance out of an overclocked Ryzen 7 1700 for $300 or less. But based on our matrix, Coffee Lake gives you the best performance (furthest to the right) without getting too crazy on price. We're naturally wondering how Core i5-8600K will fare. For now, though, Core i7-8700K is the gaming CPU to own.

Whereas Kaby Lake tends to fall behind Ryzen once we jump out of the games and start looking at rendering/encoding workloads, Coffee Lake's extra cores, higher clock rates, and overclocking headroom help close that gap. Applications previously notorious for going AMD's way are now more hotly contested.

Unfortunately, you will have to buy a new Z370-based motherboard to support Core i7-8700K. Coffee Lake necessarily breaks compatibility with the not-altogether-old Z270 chipset for higher memory data rates and improved power to the CPU's package. And of course, the Z-series platform controller hub is a requisite if you want access to unlocked ratio multipliers. Lower-end B- and H-series chipsets are coming, but not until next year.

We're also disappointed that Core i7-8700K still utilizes thermal paste between its die and heat spreader. Whereas this was a significant issue during our Skylake-X evaluation, though, it's not as problematic on a 95W CPU. You can easily stave off throttling with a heat sink and fan, or dial in a respectable overclock under a closed-loop liquid cooler.

It's an exciting year to be an enthusiast. Intel obviously planned to beef up its line-up years back, but we can thank AMD for the accelerated timeline and competitive pricing. Competition truly is a wonderful thing.
