Hi,

Does anyone know how many MFLOPS the Motorola 56001 DSP and 88110 CPU are  
capabale of?  I am trying to compare this to the 80 MFLOPS of the 33-MHx i860  
and to the 50 MFLOPS of the 33-MHz 96002 DSP.

If two 88110s can't beat the 50 MFLOPS of the 96002, then don't you think NeXT  
should use the 96002 in its future and/or current systems?  I am not suggesting  
the i860 because the 96002 provides binary compatibility with the 56001.

The i860 doesn't get 80 MFLOPS in practice.  10 MFLOPS is the number
that I hear a lot.  Anyway, the i860 isn't used for crunching on the
ND, it's just used for bitblits.

MFLOPS is a crappy benchmark, because it (like MIPS) does not include the  
instruction count.

If I understand correctly, the 56001 is capable of 0 mflops because it  
only computes integers.
