Specifications and Summary
As seems to be the trend for processor reviews as of late, today marks the second in a two-part reveal of Intel’s Coffee Lake consumer platform. We essentially know all there is to know about the new mainstream and DIY PC processors from Intel, including specifications, platform requirements, and even pricing; all that is missing is performance. That is the story we get to tell you today in our review of the Core i7-8700K and Core i5-8400.
Coffee Lake is the second spoke of Intel's “8th generation” wheel that began with the Kaby Lake-R release featuring quad-core 15-watt notebook processors for the thin and light market. Though today’s release of the Coffee Lake-S series (the S is the designation for consumer desktop) doesn’t share the same code name, it does share the same microarchitecture, same ring bus design (no mesh here), and same underlying technology. They are both built on the Intel 14nm process technology.
And much like Kaby Lake-R in the notebook front, Coffee Lake is here to raise the core count and performance profile of the mainstream Intel CPU playbook. When AMD first launched the Ryzen 7 series of processors that brought 8-cores and 16-threads of compute, it fundamentally shook the mainstream consumer markets. Intel was still on top in terms of IPC and core clock speeds, giving it the edge in single and lightly threaded workloads, but AMD had released a part with double the core and thread count and was able to dominate in most multi-threaded workloads compared to similar Intel offerings.
Much like Skylake-X before it, Coffee Lake had been on Intel’s roadmap from the beginning, but new pressure from a revived AMD meant bringing that technology to the forefront sooner rather than later in an effort stem any potential shifts in market share and maybe more importantly, mind share among investors, gamers, and builders. Coffee Lake, and the Core i7, Core i5, and Core i3 processors that will be a part of this 8000-series release, increase the core count across the board, and generally raise clock speeds too. Intel is hoping that by bumping its top mainstream CPU to 6-cores, and coupling that with better IPC and higher clocks, it can alleviate the advantages that AMD has with Ryzen.
But does it?
That’s what we are here to find out today. If you need a refresher on the build up to this release, we have the specifications and slight changes in the platform and design summarized for you below. Otherwise, feel free to jump on over to the benchmarks!
