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.
