AMD Cezanne are APUs consisting of one 7nm chip, which has a size of 180 mm2 and consists of 10.78 billion transistors, so according to these data, this chip has even more transistors than Navi 10, which is 250mm in size2. Compared to Renoir, however, according to these data, it is 15% larger and has 10% more transistors, which is probably reflected mainly in the new Zen 3 processor microarchitecture with twice the L3 cache capacity, namely 16 MB.
In addition, AMD states that these processors have 23% higher single-threaded performance compared to Renoir, which will be reflected in games, just as the Zen 3 CPUs already have unified 8-core units sharing the entire L3 cache, an improved LPDDR4 memory controller supporting faster versions , the processors themselves operate at higher frequencies and are currently the most powerful chips for gaming laptops.

Unfortunately, the published images are out of focus, but we can still read the essentials from them. As for the graphics, it still relies on the Vega architecture and offers a maximum of 8 CU as in the case of Renoir.

Even so, AMD promises at least a slight increase in performance with up to 2150 GFLOPS in the FP32. This will probably be due to a combination of GPU clock increases up to 2.1 GHz, as well as support for faster LPDDR4 4266 MT / s memories thanks to an improved memory controller.

However, these images (including the entire newly published presentation) still did not confirm to us whether Cezanne still rely on eight PCIe 3.0 lines like Renoir, or whether they already have the full number.
However, just in the afternoon, AMD announced that the first notebooks with the Ryzen 5000H are available from today, from Asus and Acer, with versions from HP and Lenovo coming soon. This also means that Cezanne is no longer subject to the information embargo and we will learn from Tom’s Hardware, for example, that they really have a total of 16 PCIe 3.0 lines, of which 8 are for the graphics card and the rest for two NVMe devices.
