The existence of the Ryzen 9 4900H APUs was first rumored back in late 2019, but now we have actual proof that the model is no mere typo, as Videocardz sources spotted a TUF Gaming laptop powered by the unannounced processor. The 45 W APU will be able to boost to 4.2 GHz, which is 200 MHz slower than the 35 W Ryzen 9 4900HS leaked earlier by Asus. Moreover, the TUF Gaming laptop appears to be missing a discrete GPU.

The photo with the specs has FA506IV written at the top. The last letter suggests the GPU is an RTX 2060. If the last letter would be a W, then the GPU would be an RTX 2070.
