Yep, the SHARK uses SDRAMS running at 66MHz (cas latency 2, according to 
the notes I have); the RPC uses FPRAMS (Fast Page mode, or whatever they 
are called) running at 32MHz, using 2 clks per S cycle and 5 per N cycle 
(RPC TRM).

So on any application that busts the cache (compiling being a pretty good 
example) a RPC+SA will tend towards just under half the speed of a SHARK.
