Interesting. Some related questions:
- Does a larger cache enable an Ivy Bridge system to use (for office work)...
-- less battery power (because it doesn't have to power memory pins as often, e.g., for screen), or
-- more battery power (because it has to power more cache)?
- Can Ivy Bridge drive the screen completely from cache when the screen is not changing?
-- and does screen resolution (pixel count) make a difference to this answer?
- When a laptop has mismatched memory capacity on its channels (8GB + 4GB seems popular),
does GPU memory come out of
-- the faster dual channel section (bottom 2/3) or
-- the slower single channel section (top 1/3)?
