CD32 with SX-32 Pro 8 MB fast gives 2.39 mips which makes it 2.5 times faster. But I really find it ironic that the add-on has this written on its board:
That's why Commodore failed with CD32 - it was supposed to be a console but it ended as cut-down Amiga that Amiga fans expanded so that it would be an Amiga computer again. But, of course, every hardware has its charms so I understand the love for CD32 that comes from some people.
