Intel's next-generation desktop CPUs haven't been released or even announced yet. Codenamed "Raptor Lake" and likely to be branded as 13th-generation Core chips, rumors suggest we'll see them sometime in September or October, but Intel hasn't officially said anything yet.

That isn't stopping motherboard makers from updating their existing motherboards to support the new chips, though. In the last month, Asus, ASRock, MSI, and (most recently) Gigabyte have all either released BIOS updates supporting the next-gen CPUs in their current-gen Z690, H670, B660, and H610-series motherboards or announced plans to do it soon.
