Discussion Xbox Helix (Magnus SoC) thread

Unless the NPU and GPU can snoop into each other's caches, the answer is probably nothing.

I saw video from GDC where they demoed co-pilot on Xbox. The idea is prob you can talk to the console and it can guide player and answer and questions. Hopefully not autocomplete BS.
That's prob the limits of the feature realistically. Maybe some background stuff offloaded. Anything else has to run on GPU due to latency reasons for reasons you laid out.

This looks like >RDNA2 spec similar to the SFS HW customizations.

Best case MS provides emulation fallback for old HW and unifies native workgraphs support via next GDK for XSX, XSS, and Helix. Also Sony does some form of emulation similar to vkd3d-proton to support it on PS5 and PS5 Pro with PS6 having native support.

Worst case everyone ignores it and we won't see games using it till +5 years from now.

Even if emulation is not optimal, it's still far better than EI. Fingers crossed we see a paradigm shift during crossgen rather than well into 2030s.
