Is the size of the data bus irrelevant?

They're wrong :-). The "size" of the CPU is defined by the size of the
internal registers. I am astonished there is actual discussion debating
this.
I think people who maintain the size of the data bus as being the
measure of a CPU are hardware people who have never optimized an inner
loop in machine code.
What do you consider 80386 to be?
how about the 80386-SX? It's hardware seems similar to 80286; what is
THAT?
32-bit. It can process 32 bits in a single operation and deposit the
results into a 32-bit register. Again, I'm astonished there is any
debate at all.
