Ryzen 5000 series mobile tests!

While AMD will announce the release of its Ryzen 5000 series mobile processors next week at CES 2021, some are already testing them. A Chinese website has published some benchmarks of the Ryzen 7 5800U CPU, based on Zen 3. AMD will indeed release the U series for laptops and the H series for gaming at CES 2021, which takes place on January 12th.

The Chinese website Uniko's Hardware has released the results of its CPU-Z and Cinebench tests of the Ryzen 7 5800U processor. This will allow us to understand the performance improvements compared to the Ryzen 4000 series, which is based on the Zen 2 architecture. The Ryzen 7 5800U is codenamed Cezanne-U. It has a TDP of 15 to 25 watts . For comparison, the H series, designed for gaming, has a TDP of 35 to 45 watts. The Ryzen 7 5800U processor has 8 cores and 16 threads . The integrated transistors operate at a base clock speed of 2 GHz. In boost mode, it reaches a maximum frequency of 4.4 GHz , which is 200 MHz higher than the 4800U series. This processor has 16 MB of L3 cache.

Ryzen 7 5800U Benchmarking

Tested on CPU-Z , this processor scores 592 points with a single active thread. Once all threads are activated, it scores 3812 points . This result allows us to conclude that this processor is very powerful. Indeed, it far surpasses the Core i9-10900K processor, which scores 584 points on CPU-Z. Regarding the Ryzen 7 5800U's CPU-Z score in multithreading, we initially suspected a software bug. The score obtained is indeed 3812 points, while the Ryzen 7 4800U CPU scores 4000 points. It is inconceivable that the new Ryzen 7 5800U could be less powerful than its predecessor, the Ryzen 7 4800U.

In Cinebench R20, the Ryzen 7 5800U CPU scores 509 points in single-threaded testing and 3614 points in multi-threaded testing . For comparison, the Ryzen 4 4800U CPU scores 479 points in single-threaded testing and 2836 points in multi-threaded testing. Tested on the R23 version, the new Ryzen 7 5800U processor achieves higher scores, with 1311 points in single-threaded testing and 9326 points with all threads active.

In short, while the Ryzen 4000 series was already known for its performance compared to Intel processors, this new Ryzen 5000 series is even better. Its architecture is entirely new: Zen 3, and the manufacturing process is now 7 nanometers. However, it should be noted that not all Ryzen 5000U CPUs will use the new Zen 3 architecture. Some will retain the older Zen 2 architecture.
