AMD Ryzen 9 4900U Mobile Processor Leaked by Lenovo

At CES 2020, AMD launched its Ryzen 4000 “Renoir” mobile APUs, with five models, going from the quad-core Ryzen 3 4300U to the octa-core Ryzen 8 4800U. However, there was no mention of a Ryzen 9 part, as seen in the desktop space. Well, it seems like Lenovo has spilled the beans and there might actually be a Ryzen 9 4900U for low power laptops and notebooks.

The 4900U was mentioned in a demo video posted by Notebook Italia. The vid details the Lenovo Yoga Slim 7 14″ and 15″. There’s an Intel variant as well as an Intel model. The latter features the Ice Lake mobile lineup, up to the Core i7-1065G7, while on the AMD side, you get up to a Ryzen 9 4900U.

We’re not sure about the core count, but the logical conclusion would be a higher clocked 8 core/ 12 thread CPU. While it’s possible that it could be a 12 core part, that wouldn’t make sense as you don’t need that kind of firepower on the go. Furthermore, the clocks would have to be much lower than competing Intel chips, hindering the performance in day-to-day single-threaded tasks. On top of that, there would need to be a bulky heatsink to prevent the laptop from exploding. Considering that the laptop weighs just 1.1kg, I’d say it’s definitely an octa-part alright.

Both laptops feature SSDs ranging from 256GB to 1TB and memory from 8 to 16GB DDR4. As for the display, you get a FHD screen with a decent 300 nits of brightness and 100% of sRGB color pallet. For the AMD model, you get integrated Vega graphics but the Intel one also has the option to include a low-end NVIDIA part, in addition to the Gen11 graphics.

Keep in mind that this is just one listing and could also be the result of an error or placeholder. There have been literally no rumors about a Ryzen 9 4900U, like none of them. So take this with a grain of salt.
