       One third-party vendor claimed to me that the SandPiper SIMMs use 80
   ns memory (presumably, they could use faster, but it wouldn't do one any
   good), so I guess the Alpha must be doing some heavy-duty pipelining. I
   guess the alternative was having memory no one could afford (the
   traditional DEC solution?).

Well, yes, it is doing some "heavy-duty pipelining", but as a previous
post mentioned, it's the cache that allows the processor to run much
faster than the main memory.  This is certainly not unique to Alpha --
even many (most?) PCs these days have to do this.
