The fastest graphics processor currently available in a laptop is the Nvidia Geforce RTX 4090, with the usual Max-Q variants. The Max-Q versions run at slower frequencies than their full-size siblings -- that keeps down the noise and heat and allows them to fit into thinner designs. RTX models also accelerate ray-traced rendering and provide intelligent upscaling (also known as DLSS) where it's explicitly supported. If your favorite games don't use it, the lower-end Nvidia GTX 1660 Ti incorporates Turing, the last generation of Nvidia's technology, without the extra cost or power burden of the RT cores.  We're finally seeing a lot more system implement Nvidia's Advanced Optimus version of Max-Q, which is great. It's smarter, with integrated and discrete graphics sharing (rather than switching) the same pipeline to the display, no reboot necessary.  The older version of Optimus, that's still used by a lot of laptops, requires you to reboot in order to switch between a high-power-draw dedicated GPU mode and a power-saving mode; the latter only uses the GPU for accelerating, not actually drawing the screen (so every frame has to travel from the GPU's dedicated memory over the system bus to the CPU and then to the screen rather than going directly from the GPU memory to the screen). That means it can't take advantage of adaptive refresh-rate technologies and it can negatively affect frame rates.  We haven't yet tested models with AMD's current high-power laptop GPUs, the RX 7600M, RX 7600M XT, RX 7700S and RX 7600S, but based on the performance of desktop 7000 series models I don't expect them to hit the highs of Nvidia's best, but they tend to be solid midrange performers. The "S" versions are the lower-power models designed to fit better in the thinnest laptops. Intel launched its first generation of Arc discrete high-performance GPUs a while back, but we've yet to see any for gaming laptops.
