One of the most contentious and long-running discussions in the world of computers is the old "My computer is faster than your computer" argument. Whilst a lot of variables come into play when testing computers, this page has been created in order to give a rough indication of 'real world' speed tests.
I've specifically avoiding using industry benchmarks, such as Dhrystone and Whetstone tests etc, as these can often give misleading results, especially when manufacturers may optimise their hardware to 'cheat' at particular well known testing protocols.
If you would like me to perform any specific additional tests, then please let me know and I can add the results to the table below.
|Description of test carried out||Acorn Risc Kinetic Risc PC||Castle Iyonix||WindowsXP PC||Apple iMac||Apple PowerBook|
|Power up machine from initial switch on to logon prompt.||28.7s||35.3s from power-up to desktop||31.7s||1m 8.28s||1m 52.53s|
|Time from entering username/password to reaching a useable desktop environment.||25.2s||11s||18.8s||33.09s|
|Time to shutdown the machine, having quit all applications.||<1s||<1s||11.09s||10s||11.76s|
A quick look at various photo manipulation and graphics speed comparisons.
As a quick comparison of graphical processing speed, I've performed the following tests on a 600MHz XScale powered Iyonix, a 233MHz Kinetic powered Risc PC and a 1GHz G4 powered Apple Mac. All timings are in seconds.
I used Photodesk Olympic edition on RISC OS and GraphicConverter on Mac OS X.

Acorn Risc PC
This is one of the last generation of Acorn computers running RISC OS. The machine under test was a RPC 700 model which has been upgraded to a 233MHz Kinetic processor and has 192MB of RAM fitted. It is installed with RISC OS Select 4.37
Castle Iyonix PC
This is the latest generation of computers running RISC OS. The machine under test was a top-end machine with a 600MHz xScale processor and 512MHz of RAM. It has an nVidia GEForce graphics card and 120GB hard drive.

Iyonix power-up - As RISC OS 5 currently doesn't have multi-user capability, the time taken is from power-on to a working desktop environment. This includes an approx. 13s of hardware delay on initial power-on. I'm not sure at present what causes this.
