Cool but I wish it had a single big APU chip like the consoles and Strix Halo - and unified memory. PCs are long overdue for adopting this change, and the only reason it makes sense to keep the separate is to make graphics cards swappable. Considering how big GPU silicon is, when you have both integrated and custom, it'd have made sense to integrate them.
I hope that if this is a success, they'll have the numbers to justify a Strix-Halo like APU with a smaller CPU but keeping the big GPU for the next generation of the device.
