Mike, What are the NPS of PF2 on your Dell Axim 400Mhz vs the NPS on an ARM at 206Mhz? Does the Dell Axim power saver mode block the Mhz down to 200Mhz during longer computation periods ie to avoid xs power consumption and overheating? TJF PS I am not sure that you can compare the two processors on a MHz per MHz basis.

For simplicity. let's just say an Axim is 16X slower than 1,2 >Ghz (it's not - but this make the numbers easier to work with). > >16x = 2^4. So we take 50 x 4= 200 points - so in the case PF2 on a Dell Axim >running Mobile 2003 is equal to 2570 to SSDF conservatively.

A 206 Mhz ARM would be about 100 points less than this or 2400 >SSDF under this scenario. IMO, it is only about 70 points less.
