AMD just released its Ryzen 4000 'Renoir' CPUs but details of its next-generation Ryzen 5000 APUs have already started leaking out. The latest details come from Dell whose documents listed AMD's next-gen processors for the mobility part which would be replacing Ryzen 4000 CPUs in 2021.
The documents were posted over at Anandtech Forum members (via Rogame & Uzzi38). It looks like AMD has already started work on its next-generation APU lineup and that is to be expected since Zen 3 core development has finished and we will be getting the first processors based on it later this year. But while Zen 3 would initially be deployed in desktop and server platforms, the mobility market will have to wait till 2021 since Ryzen 4000 just launched this month. But like the Ryzen 4000 family, AMD will again try to disrupt the notebook segment with more performance & higher efficiency unlike anything before.
AMD currently refers to its new Ryzen 4000 (Mobile) lineup as 3rd Gen simply because it's based on the Zen 2 architecture while the rest of the Ryzen 4000 processors (Desktop) will be referred to as 4th Gen since they will be based on the Zen 3 architecture. The same would be the case with Ryzen 5000 CPUs which would be referred to as 4th Gen since it will make use of the Zen 3 core architecture.
The details for AMD's next-generation Cezanne 'Ryzen 5000' processor lineup featuring Zen 3 CPU & RDNA2 GPU cores have leaked out.
