I’m guessing this is the first laptop Anandtech could get their hands on with this new chip. That said I’ve been out of the PC space for quite a while. Do mobile discrete GPUs greatly draw much power when mostly idle (such as general desktop work)? Did others give up on switching the discrete GPU on and off a needed as Apple used to do (and gave up on IIRC)?
I believe there are laptops you can buy that do that well, but it's not universal. Software support in Windows and Linux for swapping between a low power integrated GPU and a dedicated one on demand was rather spotty last time I had a system like that, but things might have changed since then (~6 years ago).
Since I rarely gamed I ended up using a 3rd party utility to force the discrete GPU off 98% of the time and the laptop was much better for it.
I understand why Apple did that (power draw when GPU on) and why they gave up (didn’t work well at all).
