I helped port a large FORTRAN program from VAX 750 to Mac II, with minimal graphics to the screen. Before adding all the Mac user interface stuff, we got a 4x speed up. Therefore, (scribbling furiously on back of envelope): VAX 11/780 == 1.0 MIPS (industry standard) VAX 11/750 == .6 MIPS (according to DEC) Mac II ==> 2.4 MIPS (my ballpark estimate) Mac SE ==> .6 MIPS or slower (no floating point chip) Mac IIx ==> 2.8 MIPS (Apple claimed 15% speedup) Mac IIcx ==> 2.8 MIPS (basically same as IIx) Mac SE/30 ==> 3 MIPS (Small B&W screen slightly faster!) Mac IIci ==> 4 MIPS (claims of 50% faster than IIcx, with cache card) Mac IIfx ==> 11 MIPS (IIfx 4x faster than IIx) I have no idea what an LC or Si are worth. Your mileage may vary. -- Rex
