Well, in this case he speaks of ARM as being the slow option. It seems safe to assume he's coming from x86, PPC, et al.
There are corner cases like DSP and high speed FPGA's, but I'm not aware of any general-purpose embedded chips that make ARM look slow.
Of course, this is only my opinion, having spent the majority of my time with embedded devices at or below 1MHz. Those 72MHz ARM cores are speed demons in comparison!
