The alleged technical specifications circulate online of the entire Ryzen range 5000 U series, formed by a mix of models belonging to the Cezanne project, based on Zen 3 architecture, and Lucienne, a Renoir refresh again based on Zen 2 core.

In 2021 AMD will present, as per tradition, a new family of APUs for the mobile segment which will be part of the Ryzen
series . The name will be the same as the Zen 3 desktop CPUs debuting on November 5th, due to AMD’s choice to skip the Ryzen family 4000 on desktop in order to align the nomenclature with the architectures.
Based on the latest rumors spread on Twitter, which reinforce previous rumors, the new range of mobile APUs will be based on two projects, one called Cezanne and one Lucienne , at least as far as the proposals of the U series with TDP of 15 W (configurable between 10 W e 25 W). Cezanne is the name of a totally new APU based on Zen 3 architecture, while Lucienne will again use Zen 2 architecture. The Ryzen range 5000 mobile will therefore be a mix of these solutions, with higher operating frequencies of 85 MHz compared to the Renoir solutions of the series 4000 and a more powerful GPU for some models than their predecessors.
| First name | Code name | Core / Thread | Base Clock | Boost Clock | Core GPU | GPU Clock |
|---|---|---|---|---|---|---|
| AMD Ryzen 5000 U | ||||||
| Ryzen 7 5800 U | Cezanne (Zen3) | 8C / 16 T | 2 GHz | 4.4 GHz | 8 | 2 GHz |
| Ryzen 7 5700 U | Lucienne (Zen2) | 8C / 16 T | 1.8 GHz | 4.3 GHz | 8 | 1.9 GHz |
| Ryzen 5 5600 U | Cezanne ( Zen3) | 6C / 12 T | 2.3 GHz | 4.2 GHz | 7 | 1.8 GHz |
| Ryzen 5 5500 U | Lucienne (Zen2) | 6C / 12 T | 2.1 GHz | 4 GHz | 7 | 1.8 GHz |
| Ryzen 3 5400 U | Cezanne (Zen3) | 4C / 8T | 2.6 GHz | 4 GHz | 6 | 1.6 GHz |
| Ryzen 3 5300 U | Lucienne (Zen2) | 4C / 8T | 2, 6 GHz | 3, 85 GHz | 6 | 1.5 GHz |
| AMD Ryzen 4000 U | ||||||
| Ryzen 7 4800 U | Renoir (Zen2) | 8C / 16 T | 1.8 GHz | 4.2 GHz | 8 | 1, 75 GHz |
| Ryzen 7 4700 U | Renoir (Zen2) | 8C / 8T | 2 GHz | 4.1 GHz | 7 | 1.6 GHz |
| Ryzen 5 4600 U | Renoir (Zen2) | 6C / 12 T | 2.1 GHz | 4 GHz | 6 | 1.5 GHz |
| Ryzen 5 4500 U | Renoir (Zen2) | 6C / 6T | 2.3 GHz | 4 GHz | 6 | 1.5 GHz |
| Ryzen 3 4300 U | Renoir (Zen2) | 4C / 4T | 2.7 GHz | 3.7 GHz | 5 | 1.4 GHz |
For example, the Ryzen 7 5700 U should have the same number of cores and threads as the 5800 U, and also the same number of Comput Units (CU) as the GPU, with the architecture (Zen 2 and not Zen 3) being the main difference. The GPU architecture, on the other hand, will always be Vega (Graphics Core Next), as the transition to RDNA 2 is only foreseen in the 2022, although optimized to reach higher frequencies.
The Ryzen range 5000 should finally see another change from the series 4000, with U series models all equipped with SMT (Simultaneous Multi-Threading) active, where three Renoir models do not have one and therefore do not offer logical cores but only physical cores.
