I don't know why the GP2X could triple the N900's performance, maybe it has something to do with the build of MAME being used?

I actually had my GP2X stolen while travelling and the N900 was its sort-of replacement, if you can believe it! I really liked my GP2X, but I have to say, the N900 surpasses it in so many ways I don't even think about it anymore, Outrun notwithstanding.

Yeah, I didn't even notice your avatar, you're the perfect person to have this conversation with! NB, the GP2X's version of MAME doesn't support Turbo Outrun, but the N900's does! Woot!
I think Flandry explained why before, but something to do with the the video ram issues with the N900. As mentioned in my other post, the MAME4All romset (.37) all plays smooth with sound on the Droid 1, which has a similar chipset as the N900. It also plays Tiger Arcade smooth with sound. Every Neo Geo game, including KOF 2003 and Metal Slug 5 plays smooth. Also all of the Capcom 2 roms.

For that matter, the slower than N900 Nintendo DS has NeoDS and plays all Neo Geo games smooth with sound. It uses the video ram form the 3D chips in the DS. Hardware design seems more critical for games like NeoGeo, Capcom and most of the older arcade games.

Since some complex shooters play smooth on the N900 at stock speed, I suggest the bottleneck is not the chipset, as much as the N900 hardware design for video ram. CPU is having to do too much work for some games. Sadly, the Capcom and NeoGeo romsets are some of the games that are constrained by the hardware.

BTW, games like Soul Calibur, Dead or Alive and other games play slow on last year's netbooks, so those ARE cpu bottleneck issues.
