Community Feedback

What Owners Say

Fans love the high boost speeds for gaming, calling it a fun special edition chip. The usual gripe is the high heat output, needing a good cooler to keep it from throttling.

Pros

Stays cool under heavy loads
Plays games with no stutter
Handles multitasking like a champ
Still feels fast for daily use

Cons

Still expensive for what it is
Needs a beefy cooler
Worse value than newer chips

Verdict

Our verdict on the Core i7-8086K

The Intel Core i7-8086K is a limited-edition Coffee Lake chip that runs faster out of the box than any other Intel desktop CPU of its generation.

Get it if you want a collector's piece or need top single-thread speed in an older Z370 build. Skip it if you're building new today, as a modern mid-range chip easily beats it for less cash.
