Unannounced top-of-the-line Ryzen 9 4900H APU spotted in the wild on an Asus TUF Gaming laptop
AMD revealed all the Renoir Ryzen 4000 laptop APUs up to the Ryzen 7 4800H at CES this year, but some online retailers had already leaked information about a Ryzen 9 4900H by the end of 2019. At first, it was not clear if that was some sort of typo in the specs listed online by said retailers, since AMD did not mention this model in the official CES reveal. Then Asus decided to spill the beans, leaking the specs for its upcoming G14 ROG Zephyrus that features a Ryzen 9 4900HS APU. To further prove that the Ryzen 9 4900H APUs are real, a Videocardz source recently revealed pictures of a real-life TUF Gaming laptop from Asus, which happens to come with specs and serial numbers printed on a sticker.
According to Asus, the Ryzen 9 4900HS model is supposed to be a 35 W TDP APU with 4.4 GHz boost clocks. We also knew that the 4900H is supposed to have a 45 W TDP from previous listings and now the TUF model reveals that this APU can only go up to 4.2 GHz in boost mode, same as the Ryzen 7 4800H. Both the H and the HS models are rumored to integrate Vega iGPUs with 8 CUs, so we are not exactly sure why there has to be such a differentiation. Furthermore, the sticker does not mention anything about the iGPU part, and what is even more odd is that it does not mention anything about a discrete GPU either.
The TUF Gaming laptops from Asus always come with discrete GPUs, so could it be that the Vega 8 iGPU in the Ryzen 9 4900H is fast enough to replace a GTX 1650 or a Radeon RX 560X? Or maybe the Ryzen 9 4900H could integrate a better iGPU?
