First and foremost, these processors are not THAT high end. They are configured on a lower 35W TDP and are “only” quad-core processors.
Today’s High-end H-series laptop processors are typically 8-cores and have a TDP of 45Watt.
As you can guess from the processor’s lower configured TDP, this laptop doesn’t have a large Thermal Capacity. Which means it cannot use high-end GPUs. On the laptop market, people mainly speak of Nvidia, which has given much more attention to high-end GPUs recently, so there is no full-fledged successor in the TDP range of the GTX 1650, which is quite old. The 3000 series laptop GPUs are around the corner, The Super revisions have also only come for the RTX 2070 and RTX 2080 in laptops.
There are already rumors about the RTX 3050, but before it comes out and a laptop version is made of it, it will take a while. And it could have a higher TDP than the GTX 1650, given that it is RTX, and that the 3000 desktop series generally also run on higher TDPs
