ah thank you. forgot about that. the figures i got were from a
special TI video processing chip, with dual 32-bit DDR3 1600mhz
interfaces. the power consumption figure was 1.6 watts per channel.
> For overclocking increasing frequency also likely means you need to increase voltage so you need to increase power consumption more than linear with frequency.
yes. i think that's where i was confused (overclocking almost always
involves increasing voltage). actually it's a huge source of
confusion across the internet, that one.
