What you lose shuffling between CPU and GPU you gain by not having your GPU and CPU sharing the same bandwidth.
Apple gets away with it by having an ungodly massive memory bus. I don’t think valve is getting a 512 bit memory bus on what’s probably a RX 7400/Ryzen 7600 tier CPU. Both of those combined would be like half that?

It’s kind of impressive how effective Apple’s marketing team was towards developers when they started that push towards ARM PCs. A lot of people can remember that having shared memory benefits from not having to copy memory between the CPU and GPU, but barely any of them remember that the only reason it’s feasible is because Apple gave their devices insanely high memory bandwidth.
On the opposite end of the spectrum, look no further than the original Nintendo Switch. With an incredible 64-bit memory bus and 1600MHz memory clock speed, it was already being bottlenecked by its memory bandwidth 2 years into its lifespan. And that’s counting first-party titles like the Link’s Awakening remaster, not even shitty ports of games made for other consoles.
