4DS - Anything but Charting, page-28447

for one thing GPU power is mostly about the processor rather than the ram. but to answer your question, 4ds ram is NOT non-volatile. if it was, they would be characterizing the "retention" data for us. retention = how long the data stays the way you put it. e.g the reciprocal of volatility.

IF 4ds DID in fact have a measure of retention that was of any value whatsoever, that would be used to calculate the power consumption, but because they dont, its a complete waste of time.

but for the sake of completeness, the reason why power consumption comes into it is because DRAM (Dynamic RAM) needs to be refreshed (rewritten with teh same data) before it becomes uncertain. IF 4ds ram had actually been what they were saying it was, and that it had retention for say, 1second, (1000ms) normal dram is refreshed aroudn 64ms for example. so this ram needs to be refreshed 1/15th of the amount. so its reasonable to assume that this ram would use somewhere between 10x and 15x less power, in this scenario. of course its all bullshit cos 4ds ram has no useful retention.
