I've been super excited for Strix Halo, but I'm also nervous. Strix Halo is a multi-chip design, and I'm pretty nervous about whether AMD can pull it off in a mobile form factor, while still being a good mobile chip.

Strix Point can be brought down to 15W and still do awesome. And go up to 55W+ and be fine. Nice idles. But it's monolithic, and I'm not sure if AMD & TSMC are really making that power penalty of multichip go down enough.

Very valid concerns! AMD's current die-to-die interconnects have some pretty abysmal energy/bit. Really hope they can pull off something similar to Intel's EMIB maybe?

The rumors saying Strix Halo will be a multi-chip product are saying it's re-using the existing Zen5 CPU chiplets from the desktop and server parts and just replacing the IO die with one that has a vastly larger iGPU and double the DRAM controllers. So they might be able to save a bit of power with more advanced packaging that puts the chiplets right next to each other, but it'll still be the same IF links that are power-hungry on the desktop parts.

The 7945HX3D needs 55W minimum, if that's any indicator.
