The RTX 4000 series also supports DLSS4. Only MFG 3X and 4X are exclusive to the 5000 series

GeForce RTX 5080 laptop with water cooling system is a respectable 25 to 35 percent improvement over average value of RTX 4080 laptops in pure rasterization

Except none of these tests used the Oasis water-cooler, all of them were done on air. It wouldn't have mattered much in GPU-bound scenarios anyways, because most of these laptops have no issue sustaining 175W on the dGPU—it's the CPU that water-cooling would make the largest difference in.
