The early 32 bit processors where indead a bit slower than contemporary 16 bit 
ones. Also, early 32 bit programms where almost always slower than 16 bit 
versions when running on the same 32 bit processor. It's worth noting that 
almost all 16 bit processors had at least 20 bit address bus, up to maybe 32 for 
the latest. Also, ALL 8 bit CPU had 16 bit address path before the 8086 (20 bit 
address space).
