AMD knocked it out of the park with its Ryzen series of mobile CPUs, but there's no question that its discrete mobile GPUs have been falling behind. The Radeon RX 7900M rights the ship by being just as powerful as the mobile RTX 4080 fur hundreds of dollars less.
Market share aint about good vs bad. I saw many people being forced to buy 2050s 3050s because there are not laptops at their price ranges. If amd shat out tons of budget laptops or high end laptops like this on stock that overtook the model amount nvidia had they would took over pretty fast. Because people buy these cheap alternatives and worry about its idle draw problems later in this market. Its that amd doesnt dish out many chips that laptop manufacturers make a lot of models for them
