VideoCardz has shared the official slides for AMD’s Zen 3-based Ryzen 5000 Series “Cezanne” Mobile processors. The slides confirm various aspects of the APU’s engineering and architecture, such as a 180 mm2 die size, 10.78 billion transistors, double the L3 Cache (16 MB), and an updated memory controller with LPDDR4 memory support.

According to one slide in which AMD elaborates upon its design goals for Zen 3, Ryzen 5000 Series Mobile processors represent a “historic” single-thread performance uplift, with select SKUs offering an impressive 23 percent improvement in that department (e.g., Ryzen 9 5980HX vs. Ryzen 9 4900H). AMD also claims that the Ryzen 9 5900HX offers up to 19 percent higher single-thread performance than Intel’s 10980HK. Additionally, users can expect up to two hours of more battery life with the Ryzen 7 5800U thanks to process improvements.

“AMD revealed that their Zen3 mobile CPU has taped out just months after the Zen2 was introduced,” VideoCardz noted. “The Cezanne APU has a lot in common with Renoir, with the only major difference being the upgraded compute Zen3 core. The GPU still relies on Vega 7nm integrated GPU, however, there has been an upgrade on this front as well. The new Vega iGPU is now clocked up to 2.1 GHz.”

“There are new power regulating features that improve battery life up to 2 hours, AMD claims. For instance, the Zen3 based APU now has a deep power state for the memory controller or the APU can now regulate voltage per core, which reduces the power input of the whole processor.”

Laptops with AMD’s new Ryzen 5000 Series Mobile processors will begin shipping starting in Q1 2021. The most powerful SKU is the Ryzen 9 5980HX, an 8C/16T processor with a boost/base frequency of up to 4.8/3.3 GHz and TDP of 45+ watts. Some of the processors, such as the Ryzen 7 5700U, leverage last generation’s Zen 2 architecture.
