The same SKU was previously spotted in Gigabyte's own CPU support list, but now @momomo_us has spotted it in China. Of course, the Ryzen 3 5100 might be an OEM-only SKU, as it is not listed on AMD's site and the CPU is marked as a 2020 model. Of course, the Ryzen 5 5600F is also marked as a 2020 model, as noted by Videocardz.com.

Unfortunately, the leak does not provide any specifications, but the Ryzen 3 5100 is most likely a 4-core/8-thread SKU with 65W TDP, and could be positioned below the Ryzen 3 5300G, making it the cheapest Ryzen 5000-series SKU.
