This is cool, but I can't help but think that running a VM on an iPad or iPhone would be horrendously slow.

The iPad Pro is very impressive, here a video of one playing Half Life 1 in XP using UTM [0]

Have you played Civ VI on an iPad? Except for being slightly harder to click on things (and no keyboard shortcuts) it plays the same as the desktop version. Same UI and graphics.

Nice.

Why would you think that? Apple's processors are very powerful.

Because it is fairly slow :)

Emulation is slow.

Emulation is slow because it is emulating a CISC processor with a RISC processor. You are better off running QEMU on your Mac than on your iPad.

Does to hard drive limitations in space might not be able to run Windows 10 on an iPad or Macbook Pro.

It’s slow because it’s emulating, period. CISC/RISC has little to do with it.

Under the hood, intel processors emulate a CISC processor with a RISC processor, so there’s nothing fundamentally slow about that.

Staying with the same instruction set (e.g. x86 -> x86) does help with performance though.

There’s a discussion of this here: https://stackoverflow.com/questions/5806589/why-does-intel-h...

Sure but if it's to emulate a computer from 1985 with half a meg of RAM, it might not be so bad :)

Edit: my bad, somehow I thought this was UAE the amiga emulator.
