At the disposal of the resource VideoCardz it turned out to be an image of a Cezanne hybrid processor crystal from AMD. As a reminder, the new Ryzen 5000 series mobile chips will be unveiled next week. The series will include chips on two architectures at once – Zen 3 (Cezanne) and Zen 2 (Lucienne).
According to the source, Cezanne APUs will be able to offer up to 8 processing cores and 16 virtual threads, as well as up to 8 Radeon graphics cores, just like the current generation of mobile Renoir (Ryzen 4000). The total number of PCIe lanes will not change either – Cezanne will receive 20 lanes. For mobile Renoir (Ryzen 4000U / H), only 8 PCIe lanes out of twenty were allocated for discrete graphics, for desktop Ryzen 4000G – 16. How much for video cards allocated for Cezanne chips is still unknown. Earlier there were rumors that the next generation Rembrandt processors after Cezanne will receive support for the PCIe 4.0 interface. Whether it will appear in AMD chips, which will be presented next week, is still a mystery.
A quick comparison of the sizes of the Renoir and Cezanne crystals indicates that the latter are larger. According to calculations VideoCardz, for new processors it should be 175 mm2which is 19 mm2than Renoir (156 mm2). The increase in die area is due to the use of slightly increased Zen 3 cores, as well as a larger L3 cache block. The upcoming next-generation AMD mobile APUs are reported to have 16MB of L3 cache, double that of the current Renoir.
Ryzen 5000 hybrid mobile processors are likely to be announced on January 12th. The series will include both the energy-efficient Ryzen 5000U chips (Zen 2) and the high-performance gaming models Ryzen 5000H (Zen 3). And only the latter will be able to offer a significant performance increase relative to Renoir processors.
