AMD has renewed the Ryzen Mobile range in recent weeks by presenting a dual offer of APU dedicated to both thin notebooks (U series) and notebooks intended for gaming and productivity (H series). We have seen how the Ryzen 9 4900HS behaves on board the Asus Zephyrus G14 and soon we will test other laptops based on the new APUs "Renoir".
It seems that AMD has not yet finished with the news. In these hours we return to talk about a new U-series chip – characterized by a 15 watt TDP – called Ryzen 9 4900U. The name had already circulated some time ago inside a datasheet of a Lenovo Yoga Slim, but this APU has never been heard of since. As we have seen, it is not part of the launch lineup.
The hardware leaker TUM_APISAK has however unearthed references to this new model in UserBenchmark and 3DMark. Like the Ryzen 7 4800U, the APU would count on 8 cores and 16 threads, while as regards the frequencies, the only data that could prove to be coherent is the 1.8 GHz base clock (like the 4800U). It is rumored that the alleged new APU can push to 4.3 GHz in Turbo boost, compared to 4.2 GHz of the current top model of the series, but it cannot be excluded that AMD justifies the name Ryzen 9 going even further.
The results indicated by UserBenchmark for the Ryzen 9 4900U APU, tested on a platform called AMD Ted3-RN, are not of great help in understanding the actual performance, even if the 136 points of the 1-core score and 198 points of the 2-point score cores are very good. The other scores are not very exciting, but being a developing chip, they could be the result of drivers and other non-optimized variables.
As for the graphic part, at the moment there is no precise information: the Ryzen 7 4800U counts on 8 Compute Units at 1750 MHz and we do not expect changes in this regard for the Ryzen 9, even if in the absence of reliable data nothing can be excluded. On the availability front, it cannot be excluded that AMD will announce something in the coming months, perhaps in early June: an APU of this type would certainly have been a good protagonist of Computex (postponed in late September due to COVID-19).
