Nubus was a 32 bits 20Mhz plug and play tecnologie
PCI is just a little improvement over NuBus (from 20Mhz to 33 Mhz at first). Later the PCI Bus was implemented in 64 bits ( mainly in G4s) and at 66, 133, 266 Mhz (PCI-X)
In the PC world it was a huge revolution, because the ISA bus that live at the same time as NuBus were ridiculously primitive.

i never knew that VESA local bus was such an improvement over ISA
and that VLB can surpass PCI/32bit! to 160MB/s potential
of course this VLB is only for 486 CPUs..  ;D
