I just bought a new Dell Axim with a 300 Mhz XScale CPU. I like it and I think it was a sweet deal at $200 (from Dell's website). From what I've read places online, though, the XScale processors don't play well with the PPC2002 platform and performance suffers. I'm able to get around 40 FPS on the blit sample, which has been enough power to write a nice game. Do the 200Mhz StrongARM devices do better than this? (Posts of games running at 50 or 70 fps indicates they might) How about the older 150Mhz versions? My real interest is to get a feel for which devices are going to be able to play my game well. If FPS scales linearly with processor speed (pretty sure it has more to do with memory latency and bandwidth) a game running at 40 fps on my device will be close to unplayable on an older 150Mhz machine.
Also, I noticed in the PocketFrog code that the display initialization code is model dependant in places. Could PF performance be improved by adding some specific initialization for XScale devices? As I understand it, there is potential performance gain that can be achieved by matching certain graphics operations with the internal orientation of the PPC's video buffer. Or maybe I'm completely wrong there. I was just wondering.
