In terms of 64 bit ARM....
RPF (Raspberry PI Foundation) recently donated optimized bitblt for
ARM64 [1] like they had done in the past for ARM32. This is not in a
current VM for long and not very interesting reasons but soonish they
will be.
If I remember I'll send a note around when ARM64 should speed up on
the graphics side.
cheers
