Mystery Next-Gen ZEN 3 AMD Ryzen 5000 APU Confirmed For Mobility Computing With Hybrid CPU-GPU Design?

The AMD Ryzen 4000 Series of APUs for laptops with Vega Graphics, codenamed ‘Renoir’, will be succeeded by the AMD Ryzen 5000 Series, codenamed ‘Cezanne’. While these next-generation mobility CPU solutions will certainly be based on the ZEN 3 Architecture, there has been some confusion about the actual CPU design and layout along with the use of onboard GPU chip.

A new mystery AMD Ryzen 5000 Series APU has surfaced online. The mystery AMD Cezanne APU, which is clearly an early engineering sample, confirms the company is actively testing and refining the next generation of powerful yet energy-efficient APUs. These ZEN 3-based processors will pack an iGPU and will be designed for laptops, notebooks, ultrabooks, and other multi-form-factor portable computing devices.

Mystery AMD Cezanne ZEN 3 APU Improves Upon The ZEN 2-based AMD Renoir Ryzen 4000 Series?

The AMD Ryzen 4000 Series of APUs are based on the ZEN 2 Architecture. These capable processors with integrated GPU (iGPU) have allowed AMD to rise as a significant player in the laptop processor segment which was hereto dominated by Intel. These ZEN 2-based CPUs with onboard Vega Graphics solutions are now one of the preferred mobility computing platforms. In fact, the top-end AMD Ryzen 4000 Series APU features an 8 Core 16 Thread configuration.

AMD recently graduated the Ryzen 4000 Series Mobility APUs to desktop-grade CPUs under the Ryzen 4000G series. These CPUs aren’t easily available yet, but they have been received well. Now AMD Ryzen 5000 Series is expected sooner rather than later.

The AMD Ryzen 4000 Series APUs, codenamed ‘Renoir’, will be succeeded by AMD Ryzen 5000 Series APUs, codenamed ‘Cezanne’. These will feature the next generation of ZEN 3 Architecture. However, AMD is not going with an equally new iteration for the onboard graphics solution. Simply put, AMD is believed to have opted for a minor increment of Vega Graphics iGPU solution.

A mystery AMD Cezanne APU spotted on SiSoftware’s website was running on a platform called “Celadon-CZN Renoir”. The information strongly suggests the Renoir as well as the upcoming Cezanne series share the same physical design.

The graphics benchmark detected that the mystery AMD Ryzen 5000 Cezanne APU featured 8 Compute Units, which translates to a total of 512 Stream Processors. The iGPU was running at 1850 MHz. Although not a significant boost, the new iteration of Vega iGPU appears to be running 100 MHz above Ryzen 9 4900H Vega Clock Speed of 1750 MHz. Interestingly, the current flagship Renoir APU also had 8 CUs.

AMD Ryzen 5000 Series Will Include Laptop As Well As Desktop-Grade Processors Based On ZEN 3 Architecture?

Needless to add, the SiSoftware benchmark detected that the APU was running on a laptop, which confirms AMD is testing a mobility computing solution. However, it is important to note that AMD Ryzen 5000 Cezanne platform is expected to debut on both mobile (Cezanne FP6 socket) and desktop platforms (Cezanne AM4 socket). The FP6 socket compatibility on next-generation APU means that notebooks makers can easily shift production for this launch and quickly accommodate these new APUs with minimal to no modifications.

We recently reported that AMD could most likely launch the Vermeer desktop-grade CPUs as AMD Ryzen 5000 Series instead of the AMD Ryzen 4000 Series. This would significantly simplify the naming and branding scheme for customers who are looking to shift from Intel CPUs. Additionally, this would mean that both AMD Mobile and Desktop-grade Ryzen 5000 Series would debut with ZEN 3 core architecture.
