AMD is expected to launch its Zen3-based Ryzen 5000 mobility APUs in early 2021, and it looks like things are going to get a bit confusing for Team Red’s fans. Apparently, the laptop-grade Ryzen 5000U APU family will include rebranded Ryzen 4000 APUs with Zen2 cores codenamed Lucienne combined with new Zen3-based models codenamed Cezanne. For example, the Ryzen 5 5500U and Ryzen 7 5700U we have seen in previous leaks are part of the Lucienne refreshes. However, today we get to see how the Zen3-based Cezanne models measure up via a new Geekbench leak for the Ryzen 7 5800U model.
According to the Geekbench database entry, the upcoming Ryzen 7 5800U APU features 8 cores / 16-threads clocked at 1.9 GHz by default (2.0 GHz might be the correct speed), which can boost to a maximum frequency of 4.44 GHz. L3 memory cache is set to 16 MB, while the iGPU is clocked at 2.0 GHz, and cTDP should be between 10-25 W. Compared to the Ryzen 7 5700U clocked at 1.8 GHz default / 4.3 GHz boost and with a 1.9 GHz iGPU, we are seeing only 100 MHz uptick across the board, so we should not really expect significant improvements. This is clearly demonstrated by the multi-core scores that are only 2.6% higher, yet, despite the DDR4 RAM clocked at only 2666 MHz, the single-core results are surprisingly 20% higher, which can be corroborated with the great single-core improvements we already see on the Zen3-based desktop versions.
Hopefully, AMD does not mix things up for the more powerful Ryzen 5000H family. Judging by previous release schedules, the 5000H series will most likely be launched a few months after the 5000U, so probably in early Q2 2021 at the earliest.
