While AMD will announce its release Ryzen mobile 5000 series next week during CES 2021, some are already testing these processors. A Chinese website has published some benchmarking with the Ryzen 7 5800U processor based on Zen 3. Actually, AMD will launch the U-series for laptops and the H-series for gaming during CES 2021 which will be held on January 12 .

Chinese website Uniko’s Hardware has published the results of testing the Ryzen 7 5800U processor with CPU-Z and Cinebench. This will allow us to understand the performance changes made by the Ryzen 4000 version based on the Zen 2 architecture. The Ryzen 7 5800U is codenamed Cezanne-U. It consumes a TDP power from 15 to 25 Watts. For information, the H series intended for the gaming world has a TDP of 35 to 45 watts. The Ryzen 7 5800U processor has 8 cores and 16 threads. Onboard transistors switch at 2 GHz. At boost clock, it reaches its maximum frequency 4.4 GHz. This is 200 MHz more compared to the 4800U series. This processor has 16 MB L3 cache.

Benchmark du Ryzen 7 5800U

Tested on CPU-Zthis processor takes 592 points with only one active thread. Once all threads are activated, it’s done 3812 points. This result allows us to conclude that this processor is very efficient. Indeed, it far outperforms the Core i9-10900K with a CPU-Z score of 584 points. Regarding the CPU-Z score of the Ryzen 7 5800U in multithreading, we assumed it was a software bug. The score obtained is actually 3812 points while the Ryzen 7 4800U CPU gets 4000 points. It is inconceivable that the new Ryzen 7 5800U could be less efficient than its predecessor Ryzen 7 5800U.

At the software level Cinebench R20, the Ryzen 7 5800U CPU scores 509 stitches with one thread et 3614 points in multiple threads. For comparison, the Ryzen 4 4800U CPU scores 479 points and 2836 points, in single-threaded and multi-threaded mode, respectively. Tested in the R23 version, the new Ryzen 7 5800U processor gets more points, namely 1311 single-threaded and 9326 with all threads active.

In short, if the Ryzen 4000 series was already known to perform well compared to Intel processors, this new Ryzen 5000 series is even more so. Its architecture is brand new: Zen 3 and the etching process is now at 7 nanometers. It should be noted though that the Ryzen 5000U processors will not all be with the new Zen 3 architecture. Some will remain with the old Zen 2 architecture.
