Core i7-8700K overclockability silicon lottery stats

Silicon Lottery, a company that sells delidded and binned chips with warranty, has published additional statistics on Coffee Lake. Specifically, the company has published new information on Intel’s current mainstream flagship processor, the hexa-core Core i7-8700K.

The part has been sorted into five frequencies ranging from 4.9 GHz to 5.3 GHz with 100% of the parts reaching at least 4.9 GHz. Note that those values are as of November 11, 2017.

 

8700K Overclockability
% of chips Frequency AVX Offset Vcore
100% 4.9 GHz -2 1.387 V
Top 81% 5.0 GHz -2 1.400 V
Top 58% 5.1 GHz -2 1.412 V
Top 30% 5.2 GHz -2 1.425 V
Top 6% 5.3 GHz -2 1.437 V

Last month (October 16), the company published similar statistics regarding the Core i3-8350K which were binned at slightly lower frequency and had a higher voltage.

8350K Overclockability
% of chips Frequency AVX Offset Vcore
Top 96% 4.8 GHz -2 1.400 V
Top 82% 4.9 GHz -2 1.412 V
Top 59% 5.0 GHz -2 1.425 V
Top 27% 5.1 GHz -2 1.437 V
Top 14% 5.2 GHz -2 1.450 V

Those values are expected to further improve over time.

My 8700K hit 5GHz at 1.2500v with a zalman cnps 9700 all copper 11 year old (but new) cpu cooler. (I know) i think i got the top 1% of binned chips. I can hit 5.5GHz at 1.35000v without it throttling. Granted i have it on a Gigabyte Aorus Gaming 7 with the vrm not even reachin 60°c. The funny thing is i bought both these parts at microcenter as open box (returned) items. The motherboard had bent pins but was sent back to Gigabyte and fixed basically to perfection and the 8700K’s box looked like it got ran over by a steel roller. I paid $280 for the cpu and S150 for the board. I needed an upgrade. Coming from a 775 socket eVGA nVIDIA 680i SLI rev.2 MB and Q6600 OC’ed to 3.6GHz. My ram in this Z370 is running faster than my Q6600 was. I can def. say i am a happy customer. I would recommend anyone that is lookin to upgrade to the Z390 or the i9 9900K. Don’t look past the 8th gen chips and z370 board from Gigabyte. Specifically the gaming 7 because it has the same vrm as the z390 EVGA DARK’ which is a $500 board. The VRM on the Gaming 7 didn’t even reach 60°c when under prime95.

Voltages dont mean crap without knowing VLL calibration or Vdroop. Things don’t go Picasso until FL anyway.
