It has some peripherals on chip.  The 386SL according to the publicized data
(i.e. EE TIMES) is a highly intergrated chipset that has some peripherals
on board.  Check out some of the hard core magazines for a better profile.

The SL differs from the SX exactly like the SL differs from the DX.  The SX and
DX don't have peripherials on chip per say.  

As for the clock rates, I've seen a press release about a 100MHZ 80X86 cpu.
(I don't think production will be very soon and I'm try to figure out how they
keep the CPU from melting the board -- must have some freon cooling)

As to the SL VS. SX no idea on the performance.  I would guess that the SL
will beat an SX if the clock speed are about the same. 

"Running faster" can always be done with a 386DX (32 bits) but if you have a
jamming 286, you might be able to beat a 386SX (16 bits * 2).
