Windows 8 Power usage & battery life

In windows 7, there was an option to switch to the old classic desktop environment, that doesn't require any GFX power.

I always noticed a difference of 20%~33% in battery life between aero and classic desktop, so I always ran on the classic look, I do not really care about the glassy look.

Now windows 8 does not allow a desktop environment that doesn't rely on GFX power.

I wonder how this will work on different laptops, specially laptops that has dedicated graphics card like ATI and NVIDIA.

Any one saw a benchmark ?
 
Thanks, but this article you posted is not exactly what I was looking for.

It keeps endlessly praising windows 8, without discussing in details the new interface alone, it is focusing on new drivers and how windows interacts with new hardware ..etc.

This article is not useful for people with 1+ years old laptops who are thinking of upgrading.

We timed battery life in normal use, with a mix of editing documents, reading Web pages, playing games, editing photos and streaming videos

I'd be more interested in something like testing watt usage on idle, to see the effect the new interface have on power usage, between:

- Windows 7 Classic desktop
- Windows 7 Aero desktop
- Windows 7 Aero with brightness turned off
- Windows 8

i.e. Testing the OS alone, without external effects.
