In terms of raw CPU power running tightly programmed routines under
8-bit mode, the IIc+ will win.  However, the IIc+ uses caching with a
mere 8k of cache memory.  Everything else on the motherboard still
runs at 1Mhz.  The IIGS, on the other hand, usually truly runs near
3Mhz (2.5, 2.6, or 2.8 depending on the thing it is doing).  There are
some times when it drops down to 1Mhz, but nowhere near what the
IIc+ is doing.

Run a small program on Applesoft that just counts loops and the IIc+
will win.  Run 8-bit GEOS (a GUI OS for 8-bit Apple IIe, IIc and that
works on the 16-bit IIGS in 8-bit mode) and it will run faster on the
IIGS than on the IIc+ despite the IIc+'s 4Mhz.
