Tuesday 12 January AMD will announce the new range of Ryzen mobile APU 5000 , both the proposals of the U series for the thinnest laptops and the H solutions for the gaming world. While waiting to have all the details of the case, the Uniko’s Hardware website has published the results obtained from anonymous sources of a laptop (a prototype) based on the new APU Ryzen 7 5800 U , tested with CPU-Z and Cinebench, two tests to broadly understand the breakthrough compared to the Ryzen 4000 based on Zen 2 architecture announced last year.

Ryzen 7 5800 U is based on Zen 3 architecture (codenamed Cezanne-U), the same we saw on board the first Ryzen CPUs 5000 desktop late last year (here and here). As this is a U series CPU, the nominal TDP of this model is 15 / 25 W, unlike the 35 / 45 W of the H series models.

From the point of view of the characteristics, the 5800 U offers 8 cores and 16 threads with a base frequency of 2 GHz and a boost of up to 4.4 GHz (+ 200 MHz with respect to 4800 U). On board there are 16 MB of L3 cache, double than series models 4000, supported by 4 MB of L2 cache. In CPU-Z AMD’s new APU totaled 592 stitches in single-thread and 3812 points in multi-thread: it is the first result to hit because it is higher even than that of the Core i9 – 10900 K (584 points according to the official rankings of CPU-Z).

The multi-thread test is instead very low and seems to be the result of a character problem software, as the Ryzen 7 4800 U scores 4000 points, so it is not possible for the 5800 U to do less. In Cinebench R 20 , the new Ryzen 7 5800 U touches 509 stitches in single-thread and 3614 stitches in multi-thread, while with the new version R 23 is passed respectively to 1311 and 9326 points. For comparison, according to Uniko’s Hardware the Ryzen 4 4800 U on a similarly configured laptop tap 479 stitches in single-thread and 2836 points in Cinebench R 20.

In short, if already the Ryzen 4000 mobile had appeared as finally competitive solutions compared to the Intel range, the Ryzen 5000 are preparing to relaunch thanks to the progress of the Zen 3 architecture and the refinement of the production process to 7 nanometers, especially in terms of single-thread performance. In conclusion, it must be added that based on the rumors that emerged in recent days, not all Ryzen APUs 5000 U will be based on Zen 3 architecture , but there should also be Zen 2 models, a refresh of Renoir solutions called Lucienne. We just have to wait a few days to get a clear and complete picture.
