Not exactly. Digits still uses a Blackwell GPU, only it uses unified RAM as virtual VRAM instead of actual VRAM. The GPU is probably a down clocked Blackwell. Speculation I’ve seen is that these are defective and repurposed Blackwells; good for us. By defective I mean they can’t run at full speed or are projected to have the cracking die problem, etc.
Pocketpal is what I run. It works well on Android at least.
