Despite being in German, it should be possible to decipher the benchmark table
The AWViewer results hint at an at least 2x faster AWViewer on Iyonix compared to a 287 MHz Risc PC. A much much higher factor compared to a ViewFinder-equipped Risc PC is achieved, and IMHO a ViewFinder is the only possibility to work sensibly with ArtWorks on a Risc PC. I don't think Kinetic will make much of a difference.
