The first block diagram of AMD's Ryzen 5000 "Cezanne" APUs based on the Zen 3 architecture has been leaked by now Videocardz. The block diagram shows that AMD's Ryzen 5000 'Cezanne' APUs will feature some major design changes compared to the current generation and are not just a simple refresh of the current 3rd Gen Ryzen 4000 'Renoir' APUs. What is noticeable is that the die is much larger than the Ryzen 4000 'Renoir', which is also due to the larger cache of Zen 3.
AMD's Ryzen 5000 'Cezanne' CPUs will be based on the Zen 3 core architecture, which is known to bring huge gains in IPC and efficiency. It is also based on an optimized 7nm process node from TSMC and also includes restructuring of the cache design along with fundamental upgrades to the core design.
The AMD Ryzen 5000 'Cezanne' CPUs and APUs will be found on both mobile and desktop platforms (if they exist at all). However, we will see it first in the mobile space and an announcement to that effect is expected as early as next week at digital CES 2021. The Ryzen 5000H and Ryzen 5000U processors, all based on the Zen 3 core architecture, are being adopted by all of AMD's major OEM partners.
In terms of configurations, the Ryzen 5000 Zen 3 CPUs will offer up to 8 cores, 16 threads, 4MB of L2 cache, 16MB of L3 cache, and 8 enhanced Vega GPU compute units with a total of 512 shaders. The L3 cache, as mentioned earlier, has received the biggest upgrade, as it was limited to just 8MB on the Ryzen 4000 "Renoir" CPUs. This significant increase will definitely help to boost the overall CPU and GPU performance of these chips. Looking at the block diagram, the Ryzen 5000 "Cezanne" is larger than the Ryzen 4000 "Renoir". It is estimated that the exact die size of the chip is somewhere around 175 mm², which is 20 mm² larger than Renoir, who had a die size of 156 mm².
Fortunately, we'll also get to see AMD's Ryzen laptop CPUs combined with NVIDIA's top-of-the-line GeForce RTX GPUs for the first time. And it's also quite possible that AMD has even more powerful Cezanne-H CPUs planned for announcement at the CES 2021 keynote in January. Rumors of Ryzen 9 5900H and Ryzen 9 5900HX CPUs have been circulating for a while now, and if Intel's Tiger Lake-H will be available in the market around the same time as Cezanne-H, we can look forward to a very heated battle in the high-performance notebook segment this year. Availability of the components provided of course.
