These should basically only be different packaging versions. You can find the two processors at https://ark.intel.com/content... (Ordering and Compliance section). The box version is Intel Core i7-12700K (LGA 1700, 3.60 GHz, 12 -Core) (BX8071512700K) and this one (CM8071504553828) is tray/reboxed. Under lithography, Intel unfortunately only specifies "Intel 7", for both. At our suppliers I find different information about the production technology (10 nm/7nm) and I can possibly imagine that both are correct (depending on the production date). But otherwise, these should simply be different packaging variants (box and tray), as is usual with other AMD and Intel processors. Both variants should be without an included cooling solution.
