The first AMD Ryzen 3 processor based on the new Zen 3 microarchitecture has been spotted on eBay, sporting impressive gains over its predecessors. The chip in question is a desktop APU, the AM4 equivalent of Cezanne, and manages to beat even the Ryzen 3 3300X which was the fastest quad-core part on the market, up until now that is. This is despite the fact that this is an engineering sample that runs at a lower boost clock with a much higher latency and cache bandwidth than expected due to the use of slower memory and modified firmware.
As you can see in the below benchmarks, the Ryzen 3 5300G is a fair bit faster than both the Ryzen 3 3300X as well as the 4350G. However, it still doesn’t quite score the same as the already existing Zen 3 parts. This can largely be explained on the basis of a lower boost clock and lack of micro-code updates as well as the inclusion of sub-par memory for the benchmarks:
