Every Intel 32 bit processor since the Pentium Pro has a 36 bit memory address bus.
Now days the memory address bus is 64 bits wide in current micro processors.
There are several other (older) processors that are 128 bit processors.
The Matrox G400 is called a 256 bit processor.

The real issue is what defines the generic name of X number of bits in a processor - memory bus, data bus, instruction size, numeric precision, ... They've all been used to define a processor. The earliest microprocessors had an 80 bit floating point processor.
