An image of AMD's Cezanne hybrid processor chip has been made available to VideoCardz resource. Recall that new mobile chips series Ryzen 5000 will be presented next week. The series will include chips that use two architectures at once: Zen 3 (Cezanne) and Zen 2 (Lucienne).
According to the source, Cezanne APU will be able to offer up to 8 compute cores and 16 virtual threads, as well as up to 8 Radeon graphics cores, like the current generation of mobile Renoir (Ryzen 4000). The total number of PCIe lanes will not change either - Cezanne will get 20 lanes. The mobile Renoir (Ryzen 4000U/H) has only 8 of the 20 PCIe lanes dedicated to discrete graphics, the desktop Ryzen 4000G has 16. Earlier it was rumored that the next generation of Cezanne processors would receive PCIe 4.0 interface support. Whether it will appear in AMD's chips, which will be unveiled next week, remains a mystery as well. A quick comparison of Renoir and Cezanne chip sizes indicates that the area of the latter is larger. VideoCardz calculates that the new processors should have 175 mm2, which is 19 mm2 more than the Renoir (156 mm2). The increase in chip area is due to the use of slightly larger Zen 3 cores, as well as a larger L3 cache block. According to available information, AMD's upcoming next-generation mobile APUs will get 16 Mbytes of L3 cache memory, which is double the size of the current Renoir. The announcement of the Ryzen 5000 hybrid mobile processors is very likely to take place on January 12. The series will include both energy-efficient Ryzen 5000U (Zen 2) chips and high-performance Ryzen 5000H (Zen 3) gaming models. And only the latter will be able to offer a significant performance boost over the Renoir processors.
