I have used my lab power supply to test CHIP's power needs.
This power supply has two main sections, one has its own amperemeter and voltmeter.
I have connected the first section (on the left) to an alpha CHIP, the second section (on the right) to a CHIP v1.

Alpha Chip uses R8m while Chip V1 uses R8.

In the picture on the left both CHIPs are idle after completing the boot process. On the right CHIPs' processors are fully loaded as I started:
<pre>
yes > /dev/null
</pre>
on both.

As you can see the results are the following:

@@ Riga 17: / Riga 17: @@
 * CHIP alpha version: idle 170mA, full load 410mA
 * CHIP v1: idle 230mA, full load 490mA.
 So, CHIP v1 is not consuming three times more than CHIP alpha, as somebody claimed, but some more (especially when it's idle... and idle power requirements are important for continuous operation devices).
