AMD Ryzen 7 5800U (Cezanne) Benchmark Leaks Out: 20-25% Faster than the 4800U in ST Workloads

After multiple Lucienne entries, a Cezanne benchmark has been spotted in the Geekbench 5 database. We’re looking at the next high-end Ryzen mobile part, namely the Ryzen 7 5800U. Unlike the recently spotted 5700U, this part is based on the Zen 3 core architecture, offering substantial improvements on the single-threaded front:


Compared to the Ryzen 7 4800U, we’re looking at a 22-23% gain in single-threaded performance and roughly 10-15% in multi-threaded workloads. One important thing to keep in mind here is that the 5800U tested was paired with slower 1330MHz memory while the 4800U ran a much faster 1600MHz kit. As such, the final single-threaded performance gain should be close to 30%, with the multi-threaded grit also improving by a bit.

AMD is going to launch the Ryzen 5000 APUs for notebooks in January 2021 (at CES 2021), along with a possible sneak peek of the mobile RDNA 2 GPUs.
