There are several more or less sophisticated tests which cater for the
variation between instruction sets. One is 'Dhrystone' (integer, memory),
another is Whetstone.
Sample approximate dhrystone figures are:
Amiga 500 1000 (cc -O)
Atari 1040ST 1000 (mwc cc -O)
Amiga 3000 5500 (cc -O)
Acorn A3000 6000 (in mode 0, 4000 in mode 15)
Sparcst. SLC 16000 (cc)
Acorn A5000 17000
PC 486/33 MHz 25000 (gcc -O)
SPARCstation II 32000 (cc)
The dhrystone test fits into mosts caches, since it is quite small.
