Intel Core i7-8086K Coffee Lake Review (Page 8)

What's Hot

Excellent Performance: While we might see that the CPU performs just like the 8700K in many tests, it's still an excellent CPU. The 8700K might spoil us in many ways and slightly tint our view of this CPU, but this is a superior CPU if we look past the price difference.

High Single Core boost: The boost clock for a single thread is 5GHz, which is 300Mhz higher than the 8700K, and in tests where that difference is measured we see the 8086K pull ahead.

Overclocking : It seems that Intel went to the line and told their machines to bin the incoming CPUs as far as they could go, and they took those bins and branded them as the i7-8086Ks. It's evident that the 8086K is a better overclocker than the 8700K. While I was able to hit 5.0GHz for one or two runs with my 8700K, 5.1Ghz would barely get past POST, and 5.2GHz was impossible. This CPU boots into Windows at 5.2Ghz with ease, and easily posts at 5.3GHz but it cannot get past the Window's load screen at 5.3GHz. If you want 5GHz all cores, this is your best bet.

Limited Edition: While Intel won't confirm how many of these they made, the retail package, even unopened, it's destined to be a collector's item, as is the note inside signed by former CEO Brian Krzanich.

What's Not

Cost: At $50 above the 8700K you are seeing gains on paper you won't really notice in real life; instead you get a better overclocking CPU and a collector's item.

Final Thoughts

For now, the 8086K is the best CPU for the Z370 platform, and it's the best overclocking CPU I have seen from Intel. Overclocking is really the strong point of this CPU if you are looking at practicality. You are basically guaranteed a 5GHz OC on all cores (I do not promise that though...). The fact that this is a collector's item also adds to its value, and you will need to consider whether or not that is enough to spend an extra $50.


Now, if you do a lot of single core stuff, like working with audio editing, then this CPU is actually worth it. However, if you want to save $50 and don't care about hitting 100-200MHz higher on all cores and the fact that it's a collector's item, then you should probably venture towards the 8700K. That being said, the 8086K is a very cool CPU, and we are recommending it as our favorite overclocking pick! It's basically hitting the overclocks people saw with Sandy Bridge, but with the increased IPC from Coffee Lake (well Skylake).

The Bottom Line: The Intel i7-8086K is a beast of an overclocker ready to handle whatever you can throw at it now, and then sit in a trophy case after it retires.
