We’ve seen tones of comparisons and tests with intel and via processors, now VIA seems to take center stage, yes VIA arena has published a detailed test result of this. (wait! The site is VIA’s own site) But the test has in-depth test results that you’d surely be interested in
Carrypad goes further to give us the results in simple words. They have a lot more information on CPU comparisons and power utilization for the UMPCs.
UMPCs - 4 hours at minimum load.
By using a VIA C7, the results show 7.31 hours of min power draw testing with a battery twice the size of an Origami battery. The maths are quite easy there because the CPU clockrate has a minimal effect on battery power at idle or low-load operations.UMPCs - under 2 hours at full-load.
The full-load VIA example is just as interesting. The laptop tested gives 3.2 hours using a 48W battery. If you take into account the smaller disk drive, small screen and lower clock processor of an Origami CPU, I think you’ll see about 55-60% of that figure for your VIA-based UMPC. That equates to about 1.8 hours under full-load. Using a Celeron, that figure will be about 1.3 hours.UMPC’s - 2.5 hour films.
In the real world, watching a film for example, you’ll be making sure that your films are under 2.5 hours long with a VIA-based UMPC. If you’re a Celeron user, I hope you’re a cartoon fan!Remember that the VIA processors have lower processing performance than Pentiums but for the average user, the C7-M ULV looks like the best choice for UMPC’s
