STREAM benchmark for various Macs

This page lists runs of the STREAM benchmark for testing memory bandwidth. The version run on these machines is the "604opt" Mac executable. If you would like to see the results for the other executables, just email me and I'll send them to you. I might put them up on the page, but that'll be later.

The PowerBook had MathLibMoto which may or may not have affected the scores any. Maybe I'll find out if it actualy does have an affect. There are LinuxPPC scores on the PowerBook as well, but I haven't gotten around to putting them up yet. I might eventually put up a Dell 233MHz PPro (EDO 66MHz), a 75MHz EDO based 375MHz AMD K6-2 system, and the same system with 100MHz SDRAM too.

I will rearrange the table so it looks better when I get other scores in. I just whipped this page up in a few minutes based on the relatively few scores I've collected.

Test values are in MB/s.
