Now, before you decided to comment on Ken's i7-8086K article, consider he is not the only one who has encountered issues with Intel's Anniversary silicon. The Tech Report offers succinct advice in their review as well "the i7-8086K isn't worth the $75 upcharge over the i7-8700K at stock speeds." They manually overclocked the chip and found the same 5.1GHz limit, as the processors are thermally identical regardless of the handpicked artisan silicon inside the i7-8086K. The 5GHz stock speed advertised does not seem to be available right out of the box but instead requires a bit of work.
On the other hand, if you like the idea of an Anniversary model CPU and would enjoy manually overclocking, the extra $75 might mean very little to you.
"Intel's Core i7-8086K is the company's first CPU with a 5-GHz Turbo speed out of the box. We dig deep to see whether this chip has the cachet to live up to its limited-edition billing."

A Weekend of Misadventure
Last Friday marked the release of the Intel Core i7-8086K to consumers through retail channels like Amazon, Newegg, and Microcenter. Announced just earlier that week at Computex, the i7-8086K is essentially an i7-8770K, running slightly higher clock speeds, and is meant as a limited edition item to commemorate the 40th anniversary of Intel’s 8086 processor, which marked the beginning of the x86 microarchitecture.
Eager to test this new CPU, I picked one up from our local Microcenter on Friday evening, and plugged it into our Coffee Lake CPU testbed, powered by a Gigabyte Z370 Aorus Gaming 7 motherboard (updated to the latest BIOS), let my first pass of automated CPU benchmarks run, and went off with the rest of my evening.
Saturday, when I came back to look at the results, they seemed mediocre at best, with the i7-8086K trading blows with the i7-8700K. While the extra 300MHz of clock speed seemed like it would provide more of a benefit than I was seeing, it wasn’t entirely unexpected that performance might not be spectacularly higher than the i7-8700K so I continued to run through the rest of our standard CPU benchmarking suite, as well as our CPU gaming benchmarks.
Finally looking at all of the data together, it appeared there was no change from the i7-8700K to the i7-8086K leading me to do some more digging.
Equipped with Intel’s Extreme Tuning Utility, I began to measure the clock speeds during several benchmarks.
Much to my surprise, even on purely single-threaded workload, such as Cinebench R15 in Single mode, the processor wasn’t getting close to its 5.0GHz Single Core Turbo Boost frequency, in fact, I never saw it get above 4.5GHz. We corroborated these issues with another piece of CPU monitoring software, HWInfo64.
As you can see in the screenshot from XTU, the processor was sitting at a cool 48C while this was going on, and no other alerts such as the motherboard power delivery or current limit throttling were an issue during our testing.
Moving to another motherboard, the ASUS Strix Z370-H Gaming, again on the latest UEFI release, we saw the same behavior.
So far, we have been unable to get this processor to operate at the advertised 5.0GHz Turbo Boost frequency, on a multitude of different hardware and software setups.
However, if we manually overclock the processor, we can get an all-core frequency of 5.1GHz, although with a temperature around 85C.
At this point, we are left puzzled and disappointed by the launch of the i7-8086K. This is the same hardware and software setup we used for all of our CPU benchmarking for the recent Ryzen 7 2700X review, with no issues. We even tried a fresh, fully updated Windows install on a separate SSD, to help eliminate any potential for weird software issues.
Jeff at The Tech Report used the same Gigabyte Z370 Aorus Gaming 7 motherboard as us, and while he didn’t see great performance overall, you can see explicit scaling in pure single-threaded workloads like Cinebench in his review.
As far as the ASUS motherboard we also tried is concerned, the i7-8086K is listed on ASUS’ CPU compatibility list for UEFI 1301 (which we are running), so it seems there should be no issue.
This morning, the i7-8086K we ordered on Amazon showed up, and did the exact same thing, in both test setups.
To be fair, based on the reviews that we have seen pop up thus far, including The Tech Report, the resulting performance if things were configured correctly doesn’t appear to be worth the extra cost.
What was meant to be a celebration of Intel’s 40 years of the X86 architecture seems more like a rushed release than a fully baked product. Remember, we bought this processor directly from a retail outlet with no intervention from Intel. Without the proper BIOS-level support, and potentially a more widespread issue affecting normal consumers building machines with i7-8086K.

The 40th anniversary of the original Intel 8086 microprocessor launch is just days away (June 8), and ahead of this VideoCardz.com has posted screen captures of online listings for the rumored 8086 anniversary CPU - the Core i7-8086K.
(Screen captures above sourced from VideoCardz.com)
"Some retailers have already started listing the new SKU on their websites, indicating 70 USD/EUR premium over i7-8700K (~480/470 EUR). Not much is known at this point, but the CPU is rumored to be 5.0 GHz chip out of the box. It is, however, still expected to be a 6-core SKU."
Beyond the online retailer listings accidentally posted early, presumably, not much is known; though it seems fair to conclude that this may indeed be a higher-clocked version of the current i7-8700K and would therefore remain a 6-core/12-thread product. Intel is going to be at Computex beginning June 5 where they "will showcase how the company is powering the future of computing" so might we hear an announcement of a new product on the eve of the 8086 anniversary? The possibility is too logical to ignore.

I kind-of hope that this is true… for the pun alone.
What do you get when the following three things happen: the 40th anniversary of your introductory part, a product line that can contain your original products model number, and, of course, strong competition from your primary competitor? Maybe the Intel Core i7-8086K. Maybe an elaborate internet hoax.

The rumor claims that it will be a slightly up-clocked Core i7-8700K. It will retain the 6 cores, 12 threads, 12MB of L3 cache, and 95W TDP, but the core will be clocked at 4.0 GHz (up from 3.7) and it can boost on a single core up to maybe 5.1 GHz. Basically, if true, it sounds like Intel cherry-picked a few high-performing dies out of Coffee Lake-S and set them aside for a promotion around the Computex or E3 time frame.
From a consumer standpoint? The last anniversary processor was a great deal, so pricing will become the deciding factor. If you were interested in the Core i7-8700K, then you might want to wait and see whether this slight notch above is true.
