The Coffee Lake CPUs are the best Intel processors around right now, and we’ve got the CPU benchmarks to help you decide which one is right for your gaming PC.
We’ve tested the best Z370 motherboards, as well as the top H370 and B360 boards for mainstream rigs, from Gigabyte, MSI, and Asus and if you want nothing but the absolute best gaming performance Coffee Lake is the platform for you. AMD may have the best overall gaming processors right now, but there is still the slightest Intel processor advantage for gamers. Though the best Intel 8th Generation chips might not be what you expect…
Check out our pick of the best gaming CPUs.
The Intel Coffee Lake CPU range has expanded this year too, with new six-core mobile CPUs, mainstream desktop processors, and affordable mobo chipsets expanding the eighth generation. There are even rumours of a potential eight-core Core i9 in the works for sometime later in the year. So, what do these 8th Gen chips offer the previous 7th Gen ones couldn’t?
Intel Coffee Lake release date
Intel's latest desktop gaming CPUs launched October 5, 2017, with the mobile gaming chips arriving in April 2018. There's also a potential 8-core desktop chip - a Core i9 maybe - possibly arriving at the end of the year.
Intel Coffee Lake pricing and availability
The top Core i7 starts at around $339 (£318), with the two Core i5s from back in October costing $250 (£222) and $179 (£160) respectively. The two i5 chips that launched in April cost $213 and $192.
Intel Coffee Lake specifications
There are six six-core chips: two K-series and four 65W. The Core i7 8700K will top out at 4.3GHz, and the i5 8600K at 4.1GHz, all-core Turbo clockspeeds. There's also three four-core i3 chips finishing the lineup.
Intel Coffee Lake CPU benchmarks
The single-core performance of Intel's new Coffee Lake chips makes them great gaming CPUs. And when you bring in the prospect of 5GHz+ overclocking that makes things tough for AMD's Ryzen.

After less than a year of 7th Gen Kaby Lake processors, Intel moved on to the 8th Gen. It might seem rather unusual for Intel to be retiring Kaby Lake so quickly, but there are a number of factors at play which are making this generation different from previous ones. For a start there is now increased competition in the CPU market from AMD’s Ryzen 2 processors, but Intel are also struggling against the continual demand for CPU die shrinks and the increasing difficulty of making ever smaller transistors.
So now we’re looking at another stop-gap processor generation, based on the same basic architecture as Skylake and Kaby Lake, as well as the same lithography Intel have been using since the 2015 Broadwell designs. Indeed there have been Kaby Lake refreshes mixed in with the Coffee Lake and Cannon Lake chips, in the form of the Kaby Lake G CPUs sporting Radeon graphics silicon made by AMD. We're actually pretty confident that was one of Nostradamus' doom-laden prophecies foretelling the end of the world.
Intel’s old-school tick-tock release cadence - where they launched a new architecture on an old process before re-engineering it again for a smaller lithography - was retired because successive CPU generations were having to stick on a particular production process for longer periods of time. It was then replaced by a new release cadence they called Process>Architecture>Optimisation... which didn’t even make it through one cycle. Now it’s just Process>Architecture>Optimise>Obey>Submit.
So if it’s all essentially the same why should we care about Coffee Lake? Well, this time it’s all about the AMD-inspired increased thread-count and a six-core i5...
Intel Coffee Lake CPUs first launched October 5, 2017, but this release date only saw a handful of chips make it to market. The initial Coffee Lake launch included some of the best gaming CPUs on the market, including: the i7 8700K, i7 8700, i5 8600K, (the stupendous) i5 8400, i3 8350K, and finally, the i3 8100.
However, only a single motherboard chipset, Intel's Z370 chipset, launched alongside these processors. It wasn't until April, 2018, that Intel finally launched the full range of motherboards to compliment the complete stack of Coffee Lake processors. The H370, H310, B360, and Q370 are now all available for purchase, although Intel have put H310 chipset production on hold for the time being due to 14nm fab limitations.
Intel also expanded the Coffee Lake CPU lineup at this time, with the i5 8600, i5 8500, i3-8300, and a handful of 35W low power chips. Intel also launched its most powerful mobile CPU to date, the i9 8950HK - a six core / twelve thread overclockable mobile powerhouse. There's also the two slightly toned-down hexacore mobile chips: the i7 8850H, and i7 8750H.
If that wasn't enough for you, Intel has now confirmed its Z390 chipset. This 14nm chipset offers native USB 3.1 Gen2 functionality and is expected to launch sometime in September - although Intel has not confirmed the launch date at this time.
Z390 motherboards are expected to be in preparation for another 8th Gen chip, the Intel Coffee Lake eight-core CPU. This octacore chip has already appeared online through various leaks, but isn't likely to launch until the end of the year, though we are hoping that an eight-core Intel i9 will also arrive along with the refreshed processor line.
Thankfully stock is far more readily available for the vanguard of Intel's Coffee Lake CPUs than they were at launch - especially since the refreshed chips made it onto the shelves in the spring.
The mainstream Coffee Lake motherboard chipsets also launched on April 3, 2018. The H370 and B360 chipsets are now available, with the Z370 still sitting in the top spot. Hold on, did someone say Z390?
Due to the long period of time between the initial October launch for Intel's Coffee Lake and the refresh in April, motherboard manufacturers have been creating some pretty budget-friendly Z370 boards. This has left the premium H370 boards in a bad spot, at least until prices for the mainstream and budget chipsets start to drop in the coming months.
Coffee Lake is the latest 14nm CPU design after Kaby Lake, which Intel is calling 14nm++ in an attempt to make it seem different. What’s making the new generation relevant, however, is the fact they’re bringing six-core / 12-thread processors into high-end laptops and standard desktops for the first time.
This is the big news for Coffee Lake: both the Core i7 and Core i5 ranges have a six-core CPU at the top. The Core i7 comes with six cores and 12 threads while the Core i5 version dodges HyperThreading and so is stuck with a straight six-core design.
That's rather exciting for us gamers because it means there’s a robust 14nm six-core part combining Intel's high-end single-threaded gaming performance with an extra two cores to give it decent multi-threaded chops too.
There were four six-core Coffee Lake CPUs at launch: a pair of Core i7 chips, one a K-series and another non-overclockable variant, and another two six-core i5 CPUs. These were joined by two new six-core CPUs in April: the i5 8600 and i5 8500. The specs show a disappointingly low base clockspeed for all the chips, most especially the Core i5 8600K.
Thankfully they have more acceptable all-core Turbo clockspeeds, especially when matched with a belligerent Asus Z370. The Core i7 8700K has a rated Turbo of 4.7GHz, which is rather stellar if we're able to hit that as a matter of course. Some motherboards, such as the MSI Z370 we used in our testing, will stick to Intel’s guidelines and only offer 4.3GHz and 4.1GHz all-core Turbo speeds for the i7 8700K and i5 8600K respectively.
There’s also two quad-core processors making their way into the budget-oriented Core i3 range too, the Core i3 8350K and Core i3 8300. The i3 8350K is essentially a Core i5 7600K with an almost budget price tag, though not budget enough considering the close proximity to the cost of the superior Core i5 8400.
Somewhat frustratingly Intel have nixxed backwards compatibility for the Coffee Lake chips, meaning you can’t just drop an 8th Gen chip into your existing 200-series motherboard. Given the Z270 and Z370 platforms look almost identical quite why the 200-series won't support Coffee Lake remains unclear, though there are suggestions it's down to the Intel Management Engine providing remote support in the corporate environment. It doesn't look like the 300-series will be backwards compatible either.
There will also be Cannon Lake chips coming later on, and potentially eight-core Coffee Lake CPUs, and that might hint at why the new chipset needs to be separated out from the last-gen 200-series. But, at the moment it's still all speculation on that front until we hear a definite yes or no from Intel. But hopefully that won't be long coming.
April also saw the launch of a handful of powerful high-end mobile CPUs. The top of the stack is the the six-core twelve thread Core i9 8950HK - marking the first i9 chip on mobile.
Following the i9 there's the two six-core Core i7 chips and two four-core Core i5s: the i7 8850H, i7 8750H, i5 8400H, and i5 8300H. All come with a 45W TDP.
Benchmark databases offer a wealth of pre-release notifications about upcoming hardware, and with the latest leak detailing what looks like an early engineering sample of an eight-core Coffee Lake chip. It looks like an engineering sample because it's running in what is reported to be an Intel test platform and the 3DMark results screen has no idea what lithography it's using or its TDP.
It does show a 2.2GHz clockspeed, which is also indicative of early silicon. That means it's likely not coming until around the end of the year... coincidentally that's when we're expecting to see the high-end Z390 chipset appear. Funny that.
Coffee Lake Core i9 anyone?
The real headline grabber from the first Coffee Lake performance tests is the fact that you can easily get 5GHz+ frequencies out of both the K-series Core i7 and Core i5 parts. You don’t have to go crazy with liquid nitrogen or set the CPU voltage to dangerous levels to get there either, and the temperatures at those speeds shouldn’t frighten you either.
With that overclocked performance the Core i7 8700K is capable of outperforming the top AMD Ryzen CPU, the 1800X, despite the fact that it has two fewer cores than its main rival. The superior gaming performance was almost a given, but the fact it can match it for general multi-threaded performance too is seriously impressive.
The problem for the two Coffee Lake K-series chips, however, is the fact that such CPU-intensive performance doesn’t matter one jot to us gamers. Even when they’re running at over 5GHz that doesn’t deliver them any extra gaming frame rates compared with the brilliant Core i5 8400.
That’s a straight six-core Coffee Lake chip, with no HyperThreading, no access to multiplier overclocking and gaming performance to rival anything on the market right now. Only the super CPU-heavy Civilization VI gives it any cause for concern. Even then, it matches the Kaby Lake Core i7 7700K benchmarks in everything from Cinebench to GTA V.
