Omega and Iyonix compared

Posted by Phil Mellor on 02:47, 19/10/2003 | , , , , , ,
 
Steffen Huber (author of CDBurn) has published a comparative review of the Iyonix and Omega on his web site - and includes a very interesting table of benchmark results. The main articles are currently in German, so you might find AltaVista's translation service useful.

Rather than simply performing number crunching, the benchmarks test for stuff users are likely to do, such as redrawing the ArtWorks apple, compressing files with SparkFS, and rendering text in Insignia. In most tests the Iyonix clocks in twice as fast as the Omega (perhaps unsurprising considering the 600Mhz vs 300Mhz processors) and the Omega runs a tad faster than a StrongARM Risc PC.

Worringly, converting a large JPEG to PNG in Creator is far slower on the Omega than a Risc PC - although the Iyonix isn't that much faster than the Risc PC either. The Omega also performs badly in a file compression test - which may indicate issues with the UDMA hard disc interface need to be resolved. For balance, apparently the Omega performs better than the Iyonix in certain situations, according to RISC OS Ltd (see Drobe's show report).

Of course, the Omega's design allows the potential for future enhancements - along with such trivial matters like networking, USB and XScale support. At least the floppy drive jolly well works now.

Bear in mind that Creator is a 26bit app so the Iyonix figure will be generated by running the test under Aemulor.

Unregistered user To avoid further confusion, I have finally translated the benchmark part of the article into English:

http://www.huber-net.de/iyonixvsomega/bench_e.htm

Real article in English coming soon.

To answer some of the questions: there are indeed situations where the Omega is faster than the IYONIX - reading from and writing to video memory. However, as you can see from the AWViewer benchmark, as long as mainly writing is used, the IYONIX is still much faster overall.

The Creator and PackDir benchmarks run under Aemulor under the IYONIX, so it is unsurprising that they are only "slightly" faster than a Risc PC - but still, they are faster! So for Aemulor-compatible 26bit software, the IYONIX is the first choice.

The current Omega is not using UDMA yet, so the filing system intensive tests will hopefully improve once UDMA is fully implemented - after all, the IYONIX also started without UDMA.

Personally, I redraw the ArtWorks apple one or two or five or twelve times a day. Doesn't everybody?

Unregistered user Well the RiscPC's are running Select 4.29, so wouldn't Creator be using the inbuilt JPEG routines, explaining why it is so fast compared to Omega (and Iyonix)?

I'm not altogether surprised that the Omega is just a tad faster than a RiscPC, although I wouldn't mind a Kinetic 300 vs Omega (300) comparison.

I would like to nominate the Artworks apple redraw as the definitive RISC OS performance test. ;)

Come to think of it, I would have to say that I do redraw the Artworks apple probably at least once a week. I have no life.

Unregistered user Simo,

Creator does not use any JPEG stuff from Select. The first version of Select (RO 4.29) does not have the ImageLoader stuff of the later versions, and the JPEG support is exactly the same as that of RISC OS 4.

Anyway, Creator does the conversion on its own - see its manual.

I am also not surprised that the Omega is only slightly faster than the Risc PC in most benchmarks - this was to be expected. However, I was very surprised to see the huge performance impact of the used screen resolution, and the fact that the Omega manages to be slower in some benchmarks than the Risc PC.
