Amiga ChipRam R/W 32bits (MB/s): 3.020 / 5.330 (SysSpeed)
No. Just no. Don't use crappy software when you want to get your facts right.
The hw bandwidth is 7MB/s read/write. Use 'bustest' to check how good your cpu is at getting the full bandwidth (I can't remember what the plain 1200 does, but it should be close to the theoretical max).
Just looking at the sysspeed page linked shows so many baloney numbers that you have to shake your head. Please don't use syssped if you want to check Amiga memory speeds.
