I think it will be different for different laptops. On my laptop i don’t think there will be any improvement. My next laptop will not be HP, probably a gaming laptop, like asus rog or acer predator.
Just save yourself trouble and don’t buy nvidia next time. Or anything with dual GPU.
I just read your comment, went into Brave and disabled hardware acceleration and now it seems to be running fine - before it was often spiking up to 85C plus, now it’s around 57C. Thanks.
