I noticed in the recent announcements that the 20Mhz MPC-100 is rated at
27 mips, and the 25MHz MPC-200 rated at 33.8 mips.
I thought that the Delta 8864SP (88K with 128K cache @ 20Mhz) was rated
at 17 mips, and the 25Mhz version at 21 mips., and I thought the MPC
systems used the same boards.
1) On the surface, it seems surprising that these machines just jumped
a factor of 1.6X in performance....
2) Could anybody that knows say:
a) Do the MPC machines have a different memory system than the
older machines?
b) Did the compilers get a bunch better?
c) Or is there some other reason for this that I've missed?
