What's N900s ARM 600MHzs like, compared to HDC HD2s and Xperia X3s Snapdragon 1GHz? Is it worse, as number of hertzs suggests or is there something more to it?
Haven't tested, so I can't tell. But the question is why would I need 1 GHz (and its quite surely considerably higher power consumption) if those 600 MHz of the N900 are actually just enough? It plays full screen 16:9 800x480 video with over 5 Mbps bitrate with STUNNING quality and without a single frame drop, it records 848x480 30 fps video, it takes 5 MPix stills, the speed of the UI is just amazing, it supports 10 Mbps HSDPA, runs a dozen of advanced applications simultaneously without noticeable performance degradation, and so on.... So why would I want something even faster?
I also think that while the actual CPU may be faster at its 1 GHz, it may actually turn out to provide very similar (or maybe even lower) performance on as resource hungry and sluggish systems as e.g. Windows Mobile.
Maemo on the N900 seems to be a very well optimized system when it comes to proper use of CPU resources and performance. For instance, it runs much faster on the N900 than Symbian OS (S60) on the Omnia HD, which has precisely the same processor...
