I think support for GPU compute has reasonable odds. I'd place worse odds on GPU support for back-end graphics rendering or display driving. And of course support for any Nvidia card would continue to have very poor odds.

Heck, we're talking about a company that put an A13 into a monitor. I wouldn't put it past Apple to put an M2 Ultra onto MPX modules and have that GPU/ANE compute performance automatically available through existing APIs. (Would be a great way to bin M2 Ultra chips with a failed CPU core.)
