At Computex 2018, Intel revealed its limited edition Core i7-8086K CPUs, marking the 40th anniversary of the original 8086 processor. It appears the 8086K is already a specially binned version of the i7-8700K, as der8auer discovered at the conference, but this has not stopped Silicon Lottery from binning them again, based on their overclocking potential. Additionally, Silicon Lottery has delidded these CPUs, replacing the stock thermal paste under the IHS with Thermal Grizzly Conductonaut. The fact that Intel uses a thermal paste, or specifically the amount of paste used, has been something the company has come under fire for recently, especially compared to AMD's strategy of soldering most of its Ryzen CPUs. Replacing the stock thermal paste may result in better thermal performance.

The MSRP of the i7-8086K is $425 and it has a base clock of 4.0 GHz with a boost up to 5.0 GHz. The cheapest Silicon Lottery 8086K is $469.99 but has been successfully tested with a multiplier of 50, so overclocked to 5.0 GHz, at a Vcore of 1.400 V. This is the same multiplier/vcore pair as the 8700K offered by Silicon Lottery, though at the price of $429.99. All of the 8086Ks Silicon Lottery tested were able to reach 5 GHz or greater, while only 86% 8700Ks can do the same, and these are at the same settings, remember. Actually, I think comparing these test results might be interesting, so here is a table of them:

Multiplier Vcore (V) 8700K Percentage 8700K Price 8086K Percentage 8086K Price
50 1.400 86 $429.99 100 $469.99
51 1.410 50 $479.99 92 $499.99
52 1.425 17 $689.99 60 $589.99
53 1.435 N/A N/A 14 $859.99

Looking at these results, I wonder how much lower the Vcore could go for some of these 8086Ks.

By the way, it appears AMD is having a little fun with the one-day sweepstakes Intel held, where people could win a Core i7-8086K. Instead of keeping the limited edition CPU, you could instead send it to AMD, getting a Ryzen Threadripper 1950X CPU. Only the first 40 people from the United States to apply for the offer will be offered it.

My question is - allowing for water cooling (good setup), what is the life of a stock 8700K vs an overclocked 8700K. I would think the voltage boost would eventually push the VRMs to extinction let alone the CPU.

If cooled properly and kept under max temps/vcore, you are not degrading the chip by overclocking, same thing with high end motherboard VRMs.


And if your running hot with poor air flow, inadequate cooling, exceeding max temps/vcore, throttling,.. your degrading killing your hardware.  


High end overclocking boards are overbuilt to withstand higher voltage, if cooled properly with water or proper air flow across all areas that generate heat, you will be upgrading platform long before anything degrades or fails due to overclocking.  :)
