Don't know about the older suunto ones, but the computers I know the adjustable sample rates are only for logging. Not for actual calculations or display on-screen.
Question about dive computer sample rate?

I usually read instantaneous values for the depth - I wear a Perdix, a Suunto HelO2 and sometimes a D6i also and their readings change simultaneously.
I never changed the default sample rate that is what recorded in the log. I can also say that, the max depth, even if recorded in the summary, sometimes it is not reported in the log because did not occurred during a sample period, but just for very limited time.
For what concerns the temperature reading, I never put much focus on its speed, but, because it always took some times to adjust when entering into the water, I ascribe it to inertia due to the mass surrounding the temperature sensor. So it will always be delayed regardless the measuring rate.
Anyway, I don't think it's so important to know the exact time when the temperature reached that value, isn't it ?

As far as the computer itself is concerned, it only needs to sample at its deco recalculation rate or logging rate, whichever's faster. I'd expect the display updated at a second or faster resolution -- but wouldn't be shocked if an older device did it slower. There's probably nothing to be gained by recomputing deco more often than every 30 seconds so if an old computer also updates its display that infrequently: it's a bit ridiculous but not entirely unreasonable.
