We don't know what Intel is planning to unveil at CES officially yet, but according to reports, we can expect new processors and motherboards. The 13th Gen Core desktop processor lineup should expand with the introduction of non-K CPUs, as well as more affordable B-series motherboards.
According to ITHome (via VideoCardz), Intel will announce the desktop 13th Gen Core non-K chips and the B760 motherboards at CES 2023. The report doesn't mention H770 motherboards, so we're still unsure if those are on the way.
The announcement is scheduled for January 3rd, likely during Intel's keynote at CES 2023. During the event, Intel will probably share a list of all the upcoming chips, which should include 16 models, ranging from i3 to i9 CPUs with 35W and 65W TDPs (the non-K i3 may come with a 60W TDP).
Besides the new desktop chips and motherboards, Intel is also expected to announce the mobile 13th Gen Core series. Some also believe we could see more about the Core i9-13900KS, but that hasn't been confirmed yet.
KitGuru says: CES 2023 is stacking up to be quite the event, with Intel, AMD and Nvidia introducing new products to the mobile and desktop market.
