Intel Core i7-8086K Anniversary Limited Edition, 5 GHz, 6 Core, 12 Thread Processor Review

Test Setup

For testing, we used the latest Intel Core i7-8086K, Core i7-8700K and Core i5-8600K CPUs which were sent to us by Intel. The Intel Coffee Lake family comes with a higher core count on the mainstream platform but prices are close to the predecessors in the same segment. The CPUs were tested on the AORUS Z370 Gaming 7 motherboard.

Intel Core i7-8086K Test Bench:

Processor	Intel Core i7-8086K
Motherboard	AORUS Z370 Gaming 7
Power Supply	Corsair RM 750X Gold Plus
Solid State Drive	Samsung SSD 960 EVO M.2 (512 GB)
Memory	G.SKILL Trident Z RGB Series 32 GB (4 x 8GB) CL16 3600 MHz
Video Cards	MSI GeForce GTX 1080 Ti Lightning X
Cooling Solutions	Corsair H115i GTX
OS	Windows 10 64-bit

Our test rig includes the Samsung 960 EVO 500 GB SSD that boots up our main OS while a 2 TB Seagate HDD is used for demonstration purposes for the Intel Optane memory. In addition to these, we are running an MSI GeForce GTX 1080 Ti Lightning X graphics card, a Corsair RM 750X Gold Plus power supply and 32 GB of G.Skill provided Trident Z RGB series memory which runs with a clock speed of DDR4-3600 MHz. For cooling, we used the Cryorig R1 Ultimate and Corsair H115i PRO coolers to see how the new Coffee Lake CPUs perform on both air and liquid cooling solutions.

We won't be focusing on Intel's Core i7-8086K architecture in this review since it is entirely the same chip as Skylake along with minor improvements. The Skylake / Kaby Lake architecture analysis can be seen in detail here. For overclocking, I made the following tweaks to the CPUs:

• Intel Core i7-8086K @ 5.3 GHz With 1.373V (100 x 53)
• Intel Core i7-8700K @ 5.2 GHz With 1.358V (100 x 52)
• Intel Core i5-8600K @ 5.1 GHz With 1.280V (100 x 51)

WCCFTECH RATING

The Intel Core i7-8086K features great performance out of the box and celebrates one of the most iconic moment in the x86 architecture history but the Core i7-8700K does almost everything that the 8086K could do for $70 US less.

Pros

• Great out of the box performance (4 GHz base / 5 GHz boost clocks)
• Fastest Intel 6 core processor as of right now
• Faster multitasking performance
• Excellent Gaming performance
• Features enhanced 14nm++ process node and 6/12 core config
• Over 4 GHz boost across all cores at stock configuration
• Great overclocking capabilities

Cons

• Very high price ($429 US)
• Very high power consumption when overclocked
• Very high temperatures when overclocked
• Performance not that great when compared to the Core i7-8700K (both stock and overclocked)
