A direct quote from the Byte Magazine article describing the new SE/30 ...Clearly, this machine is in a whole different league than the standard Mac SE. In particular, note that processor-intensive tests, such as the Sieve, String Move, and floating-point tests, show the SE/30 sometimes outperforming the standard SE by almost and order of magnitude. To be fair, I should note that the standard SE does not have an FPU. ALMOST AN ORDER OF MAGNITUDE FASTER, ALMOST...a 16 MHz 68030 with a 16 MHz 68882 is NOT EVEN AN ORDER OF MAGNITUDE FASTER than a <12 MHz 68000 WITHOUT a floating point coprocessor? Is this for real?

Is this for real? etc., etc... Pipe down. This is the 68030 doing (in)SANE float calculations. Someone ought to post an SE-SANE vs. SE/30-SANE vs. SE/30-68882 benchmark. If it runs as usual the 68882 will run wide open about 100 times faster (doing the FP directly) than through the marginally SANE libraries ... -- v v sssss|| joseph hall || 201-1D Hampton Lee Court v v s s || jnh@ece-csc.ncsu.edu (Internet) || Cary, NC 27511 v sss || the opinions expressed herein are not necessarily those of my -----------|| employer, north carolina state university . . . . . . . . . . .
