AMD's 4th Generation Ryzen APUs codenamed 'Renoir' that are based on the new 7nm Zen 2 core architecture have been spotted along with their performance benchmarks. The AMD Renoir family of APUs would be introduced around CES 2020, offering better compute performance than existing 3rd Gen 'Picasso' family while the 7nm process node would increase its overall efficiency, making them a great option for mobility products such as notebooks and gaming laptops.

AMD's 4th Generation Renoir APUs (Ryzen) will be based on the 7nm Zen 2 architecture and would succeed the 3rd Generation Piccaso APU lineup which is based on the Zen+ core architecture. The 7nm APU family would have a lot of new features to talk about aside from the Zen 2 cores, it would be highly efficient than the current 12nm Zen+ parts and would feature a new graphics engine that would either be entirely Navi based or a hybrid Vega core with a more modern feature set.
