It’s a slightly more performant GPU with a worse CPU than a Z1. (Zen3 vs Zen4, 680M vs 740M)

But we’re talking very slightly better GPU performance, so calling it essentially equivalent for gaming is probably perfectly reasonable.

Except, of course, you can find the Z1 Ally for $250 at BestBuy damn near any day of the week, soooooo uh, yeah that pricing huh.
