AMD's Ryzen 7 5700G Desktop APU which will be part of the Zen 3 powered Cezanne lineup has appeared at eBay. As per the listing by the seller who got an engineering sample of the chip, the Ryzen 7 5700G is a fully functional processor that delivers a great performance that you'd expect from a modern 8 core CPU.

Given that this particular chip is an engineering sample, the final specifications might change but we have already seen the chip in various leaks so the specifications including the clock speeds are close to the final retail chip. The AMD RYzen 7 5700G is part of the Cezanne family that comes with a major architecture change in the form of Zen 3 over the Zen 2 based Renoir offerings.
