These results are promising and hopefully carry over to the upcoming Strix Halo which I’m eagerly awaiting. With a rumoured 40 compute cores and performance on par with a low power (<95W) mobile RTX4070, it would make an exciting small form gaming box.

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.

I hope Strix Halo gets a desktop motherboard (no socket :-( for the memory bandwidth for faster compiles (Go). That or a 9950X3D (like the 7950X3D).

  Me too. There's at least one manufacturer who makes pretty sweet mini-ITX motherboard with R9 7945HX, I hope they will follow up with Strix Halo once it's released.

That kind of performance will still require significant cooling, which if you want it to be quiet is helped by a larger box.
