Silicon Lottery: Roughly 20% of Intel Core i7-10700K achieve a stable 5.1GHz 24/7

We mentioned Silicon lottery quite a few times already if you are interested in purchasing a processor can guaranteed to reach a certain overclocking frequency, you can purchase them binned. Comet Lake has been added to the Silicon lottery lineup and reveals some interesting facts.

Silicon Lottery, dedicated to selling binned and pre-tested/validated tweaked processors, launched their first Core i7-10700K in versions that reach 4.9GHz, 5.0GHz and 5.1GHz on all-core overclocks. Along with each product, it has been shared what the percentage of chips reaches that binned frequency..

According to these statistics, 20% of the chips reach 5.1GHz with 1.4V in BIOS (1.32V), 68% reach 5.0GHz with 1.375V in BIOS (1.3V), and 100% reach 4.9GHz with 1.35V in bios (1.28V). They all hit an extra 100MHz when using only 4 cores.

Speaking generally this means that 5.0GHz on 8 cores and 5.1GHz in 4 cores hits 68% of the processors available. This also means that 20% of the processors can reach 5.1GHz in its 8 cores and 5.2GHz in 4 cores.

The particular details about the testing methodology and the different adjustments can be found on the official Silicon Lottery site by clicking on the product pages, whose links can be found below:

Do always find it funny, that they keep trying to push the GHZ when they reached this cap back in sandy bridge days, my 2700k got to 5ghz, Knew some people who could push a little more than that but it was rare. But they just pushing the thermal limits of the design, either need a new one... or as I've been saying for years just more cores and get devlopers to use them effectively

20% hitting 5.1 is pretty good considering how high that is, I was hitting 4.5 on my sandy and ivy bridge CPU's when they where relevant and that was amazing then.

4.5 was bare minimum on those CPU's. I have 2 3770K's, one hits 4.7 and one 4.9

Maybe i lost the lottery i even delidded the 3770k but temps easily hit between 70 and 80c at 4.5ghz with a 240mm aio that's as far as i was comfortable with.

Yeah something off there. I ran a delidded one in a custom loop at 4.9/1.416v for a few years and temps stayed in the 60's in IBT. The 4.7 was cooled with an NH-D14 running at 1.44v and even it barely got into the 70's.

Been a while since i had that system now but i remember being around the same voltage somewhere between 1.4 and 1.45 oh well i always find i get shafted compared to hilbert here and others in forums even my 2 ryzen+ CPU's and flare-x kits refuse to go any higher than 3266mhz ram speed.
