The Pentium has the same 32-bit address and data bus internal to the chip as
the 486 series. The wider addressing modes are synthesized by a decoder unit
which breaks memory transactions into 32-bit units.
The agressive write-through cache subsystem in the Pentium is severely
hampered on systems such as laptops which don't have L2 caches (SRAM sucks
almost as much power as a Pentium chip).
