I say first, don't expect magic. These GPUs are all limited by power consumption. There is no point in dumping in more cache, more CUs, more clockspeed etc because its only going to drive up power consumption.
These GPUs on'y have 15-30W power envelope, so even a GTX3090TI is absolutely useless here. And then, there is thermal too.... Cooling in these laptops are nowhere near decent, mostly even inadequate.
This is why I said earlier that the performance is pretty decent. You will find many of these GPUs in thin and light laptops weighing less than 1.5KG, so you can imagine the environment these chips and in and the cooling capacity. USers only expect them to be better than the integrated GPUs by Intel/AMD, thats all.
