RISC OS Performance Page

[Computers]  [Home] [Links] 

This page is to show the relative performance of RISC OS computers. Benchmarks may not mean a lot but this does at least show how performance has changed over the years. Running these benchmarks clearly shows that their performance depends in part on the screen size, the greater the scrren size and number of colours, the worse the performance measure. To try and ensure consistent results I have run the benckmark programs in mode 15 for the earlier Archimedes computers and 800x600 at 60MHz and 256 colours, any exceptions to this will be highlighted. To minimise the impact, if any, of other programs on !Alarm and !Edit will be on the icon bar. The results are also shown under the individual computer. My chosen measures are:

  1. Mathias Seiffert's !SICK 1.22 for Dhrystones/sec and kWhetstones/sec
  2. J.Abbott & Nick Smith ARMSi v4.0 (7 Aug-1996) for MIPS

Please note that these benchmarks were collected from the actual computers in my collection, with their unique combination of hardware, software and modifications. There is no guarantee that you will get the same results on your computer!

1. !SICK abends when run on an ARM7 CPU (ARM710 or ARM7500) which means I do not have Drystones/sec or kWhetstones/sec figures for these systems. This bug was fixed in V1.26 and I must retest the ARM710/7500 computers which failed.
