Intel i7 8700K bins have improved since January despite the i7 8086K’s release

Since the release of Intel’s new Limited Edition i7 8086K processor, it has been speculated that bins for the company’s Coffee Lake flagship, the i7 8700K would achieve lower average clock speeds as a result, in effect limiting the silicon’s overclocking potential to by allocating Intel’s best chips to i7 8086K production.    

Silicon Lottery, a website which sells delidded and pre-binned processors, has released statistics regarding the silicon quality of Intel’s latest i7 8086K processors and has updated their data on Intel’s i7 8700K, confirming that Intel’s i7 8086K can achieve higher clock speeds on average. They found that Intel’s limited edition i7 8086K can achieve 5GHz overclocks on 100% of their tested samples, with 60% reaching 5.2GHz. 

WikiChip has taken this data and created the below tables, comparing i7 8700K binning data over time while also comparing 8700K data with Intel’s i7 8086K. From the chart below we can see that Intel’s limited edition i7 8086K offers increased overclockability over their standard i7 8700K, with 50% of i7 8700K processors reaching 5.1GHz while 60% of i7 8086K processors reach 5.2GHz.

With this data in mind, it is clear that Intel has allocated their best chips to i7 8086K production, though that doesn’t mean that i7 8700K has gotten worse, in fact, Silicon Lottery’s data shows that binning has improved since January, despite Intel’s i7 8086K production. Now, i7 8700K buyers are more likely than ever to get a 5GHz capable processor. 

Strangely, Intel i7 8700K offered users higher clock speeds on average at launch, probably due to Intel being extra cautious at the time of Coffee Lake’s release, with average overclocks getting significantly lower moving from November to January. In January, the likelihood of getting a 5.2GHz or 5.3GHz i7 8700K decreased by around half, a change that is possible due to Intel’s scramble to meet high Coffee Lake demand in late 2017. 

Silicon Lottery has stopped selling 5.3GHz i7 8700K processors, though this is likely due to the i7 8086K’s release as 5.3GHz is much more common on this SKU. It is also expected that 5.3GHz i7 8700K processors have gotten less common since January, as these dies are most likely to be allocated to i7 8086K production.
