AMD Ryzen 5 5600F isn’t the only new AM4 CPU

Mysterious Ryzen 3 SKU found on Chinese internet.

AMD has apparently released a new CPU, but never told anyone about it. In fact, this SKU had already appeared on our site in 2023 , when Gigabyte mentioned such an SKU in the CPU support list. However, it was never seen anywhere until now that Hardware detective @momomo_us shared a picture apparently from a Chinese retail platform showing a Ryzen 3 5100 CPU.

The CPU appears to be labeled as “100‑00000456” OPN Code, which returns no results. The CPU is also marked as a 2020 model (same as the 5600F, by the way), which means it’s not a new SKU. One would think that this might be a special OEM version, so rare that even AMD didn’t bother to mention it on its official website. The fact that it appeared on a Chinese site also suggests it was not meant to be released globally.

Unfortunately we can only speculate about its specs, but given that the 5300G already has four cores, this SKU almost certainly has the same core count or lower (hopefully not). The 2023 leak mentioned it is based on Cezanne and features four cores. When asked, Momomo responded by sharing our old leak, which we assume means that the specs were accurate. If that’s the case then the CPU should have a 3.8 GHz base clock and a 4.2 GHz boost clock. Worth noting that the CPU has no GPU block listed, which likely means it has no integrated graphics.

AMD’s AM4 socket has just crossed its ninth anniversary on the market. It started with pre‑Zen era APUs and ended with Zen 3 architecture. If the naming convention hasn’t changed for this SKU then it should also be a Zen 3 SKU. Most likely as an AMD “Vermeer” silicon but could also be based on Cezanne.
