Dell has this Alienware m17 17" gaming laptop equipped with AMD's most powerful CPU and GPU for $2600.
Likewise, the AMD Radeon RX 6850M is currently AMD's most powerful mobile GPU and its performance hovers somewhere in between the RTX 3070 Ti and the RTX 3080.
An equivalent Intel-based gaming laptop equipped with an Intel Core i9-12900HK CPU and an RTX 3070 Ti or 3080 GPU would easily run over $3K-$4K.
