How does Alienware handle power sharing between the CPU and GPU?

I'm looking for a beast of a gaming laptop and I'm wondering how Alienware handles power distribution between the CPU and GPU.

Most gaming laptops, even with those huge power bricks, have a single power pool for the CPU and GPU. This means they fight for power when you're gaming hard. It's like trying to share a single pizza with a really hungry friend. The CPU and GPU might get hungry, and that can cause stuttering and lower frame rates in demanding games.

So, which Alienware laptops have separate power supplies for the CPU and GPU? I know a lot of gaming laptops from brands like Asus and MSI share a power pool.
