Non-K Intel Alder Lake CPU specs confirmed by Asus and Colorful

Written by

In brief: Intel is expected to reveal the non-K versions of Alder Lake (12th-gen Core) at CES on Tuesday, but Asus and Colorful have confirmed some of their specifications in advance. Some models are a bit disappointing, while others are compelling options for the non-overclockers out there.
It’s not uncommon for motherboard vendors to include unreleased processors in their lists of supported hardware, which is what’s happened here.
In the tables below, we have core counts, base clocks, and TDPs from Asus and Colorful, and the boost clocks from leaked marketing materials and prematurely published product pages. Not included in the tables are the leaked prices from Best Buy, but you can look at those here.
*There are both vanilla and “F” versions of this processor and they share their specs.
According to Asus, Alder Lake uses two steppings: C-0 and H-0. Both the i9 and i7 families use the C-0 stepping, which has eight performance and eight efficiency cores. The H-0 stepping has six performance cores and no efficiency cores.
Intel separates the two steppings at the junction between the 12600K, which uses the C-0 stepping, and the 12600 (non-K), which uses the H-0 stepping. Because of this, the 12600K has four efficiency cores that the non-K doesn’t have.
All of the non-K i5 and i3 processors use the H-0 stepping.
*This is the only “F” processor to have a lower TDP than its vanilla counterpart.
It might’ve made sense for entry-level parts to use efficiency cores. But, because the H-0 stepping has none, they’re stuck with hungry performance cores.
Intel will announce these processors in a few days, and we’ll be benchmarking them and drawing conclusions soon. But in the present, they seem like a worthy addition to the Alder Lake generation, which is all that we can ask for.
