Blender Renderting Time (On computers available to me)

This a simple test of  of the rendering time of  blender internal render.
I was curious how Xoom or Azure compares to my desktops and laptops. However, running blender in the chrooted ubuntu of  my xoom causes a segment fault ( for both the ubuntu blender and a 2.66 blender compiled by me).

The test .blend file is my Python Girl video.  The video has 800 blender rendered frames (frame 600 - frame 1400). But in this test, only one of every 4 frames between frame 1250 and frame 1346 are rendered. We measure the difference between the modified time of 1250.png and 1346.png.

The blender used in this test is freestyle branch. On windows,  a 32bit executable is used. 64 bit binaries are used on linux and OSX.
The followings are the results:
  • Core i7-2700 Ubuntu 12.10: 19min 16sec
  • Azure extra large 8 core Ubuntu 12.10:  32min 45sec
  • Core 2 Quads Q9500 Win7: 53min 8 sec
  • Macbook Air Core i5-3317u: 60min
  • Win8 Core 2 Duo T5600: about 3 hours (I had a train to catch, so unable to finish the rendering)

The segment fault on  Xoom could be caused by kernel incompatibility or because Xoom does not have enough RAM. But compiling blender on Xoom took like 10 hours while compiling on my Core i7 desktop took only 10-20 minutes.
If possible, it would be interesting to run the same test on an ipad, iphone, EC2,  raspberry Pi, or high end android phone like HTC One, Butterfly, or may padfone infinity, S4.
