While AMD will announce the release of the Ryzen mobile 5000 series next week during CES 2021, some are already testing these processors. A Chinese site has published some benchmarking with the Ryzen 7 5800U CPU based on Zen 3. AMD will in fact release the U series for laptops and the H series for gaming during CES 2021 which will take place on January 12.
The Chinese site Uniko's Hardware has released the results of testing the Ryzen 7 5800U processor with CPU-Z and Cinebench. This will allow us to understand the performance changes made since the Ryzen 4000 version which is based on the Zen 2 architecture. The Ryzen 7 5800U is codenamed Cezanne-U. It consumes a TDP power of 15 to 25 Watts . For information, the H series intended for the world of gaming has a TDP power of 35 to 45 Watts. The Ryzen 7 5800U processor has 8 cores and 16 threads . The integrated transistors switch at 2 GHz. In boost clock, it reaches the maximum frequency of 4.4 GHz . That is 200 MHz more compared to the 4800U series. This processor has a 16 MB L3 cache memory.
Ryzen 7 5800U benchmarking
Tested on CPU-Z , this processor obtains 592 points with a single active thread. Once, all threads are activated, it gets 3812 points . This result allows us to conclude that this processor is very efficient. Indeed, it greatly exceeds the Core i9-10900K processor with a score of 584 points on CPU-Z. Regarding the CPU-Z score of the Ryzen 7 5800U in multithreading, we thought it was a software bug. The score obtained is in fact 3812 points while the Ryzen 7 4800U CPU obtains 4000 points. It is unthinkable that the new Ryzen 7 5800U could be less efficient than its predecessor Ryzen 7 5800U.
Cinebench software , the Ryzen 7 5800U CPU obtains a score of 509 points with a single thread and 3614 points in multi-threading . For comparison, the Ryzen 4 4800U CPU scores 479 points and 2836 points, in single-threaded and multi-threaded mode, respectively. Tested on version R23, the new Ryzen 7 5800U processor obtains more points, i.e. 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 range is even more so. Its architecture is brand new: Zen 3 and the engraving process is now at 7 nanometers. It should nevertheless be noted that the Ryzen 5000U CPUs will not all be with the new Zen 3 architecture. Some will remain with the old Zen 2 architecture.
