More power AMD Ryzen 4000 APUs have been spotted a day after the first chip leaked out in the 3DMark benchmark. The new processors, which are part of the Renoir APU family, will be offering even more cores and threads than we had expected with a launch scheduled for early 2020.

We got to see some of the 15W Ryzen 4000 U-series SKUs yesterday with the leak of the Ryzen 7 4700U APU. Today, we are looking at three 45W SKUs, all of which have some beefy specs and will rival Intel's 9th Generation mobility SKUs. The details come from Mobile01 Forums where a user has revealed that the top SKUs of the 45W Ryzen 4000 APU lineup would be the Ryzen 9 4900H & the Ryzen 7 4800H.
