Or are people trying to boost the performance of the SE > in their minds to save the machine? How about some benchmarks? A few years ago, I ran a benchmark on every computer I could find. I used a variety of text-book examples, each chosen to find out something specific about the machines. Here are some of the numbers. Chip Machine Run Time (Seconds) ----- ------- ---- 8088 IBM-PC 343 8086 ATT 6300 242 68000 Mac + 200 68000 Mac SE 189 80286 AST286 55 80386 ATT 6386 42 68020 Mac II 42 Although I have not mentioned processor speed, each was state of the art at that time. Take a close look at the Mac + and Mac SE numbers. About a 6% difference overall. I also looked at individual numbers for each of the ten parts of my benchmark. It looks like this: Component Tested % Mac SE Is Faster Than Mac + ---------------- ----------------------------- Integer Math 0% Floating Point Less Than 1% Sorting 7% Disk & I/O 15% Recursive Procedures ~25% (PS-please insert some type of standard benchmark disclaimer here.) As far as I know, the 68000 in the Mac SE runs at exactly the same speed as the 68000 in the Mac Plus--7.133MHz. The integer math number above would seem to support this claim. The differences in the SE are more modern ROM routines and improved I/O. The I/O speed was just enough faster to allow 2:1 interleave rather than the 3:1 suggested for the Mac Plus, which speeds up the fixed disk access a bit. > I ,myself, am almost completely content with my Plus. Same here, once I got rid of that stupid hi-rise keyboard. I still need to have a unix machine around though (to unpack the news 8-). -john- -- =============================================================================== John A.
