AMD has officially announced its brand new Radeon RX 6000M Mobility lineup for gaming laptops which are powered by the RDNA 2 graphics architecture. The lineup consists of several variants & various GPUs that are going to power premium notebook designs based on Ryzen 5000 platforms.

While the AMD Radeon RX 6000 Desktop lineup starts with the Navi 21 GPUs, the Radeon RX 6000M Mobility lineup is starting with the Navi 22 GPU. The reason is plain and simple, just like the NVIDIA Ampere GA102 GPU, the Navi 21 GPU is just too big and too power-hungry for laptops to handle, as such, both companies are offering their 2nd best GPU on gaming laptops. NVIDIA's best chip on the platform is the GA104 and AMD's best chip is the Navi 22.
