Without having ridden a bamboo board, I feel I can describe the difference in pop just based on the reviews I've read here on the forum and other websites.
Bamboo has linear pop. Which is to say that it's predictably even in its release of energy. On a graph it would be a straight ascending diagonal line. Whereas other board materials have non-linear (or exponential) pop. The power delivery would look like a half of the letter "U" on a graph. The boards with carbon fiber rods have even more exponential pop. Classic materials and classic materials incorporating carbon fiber rods/stringers translate into a more "explosive" ollie. Explosive is an exaggeration but I think the idea provides a good illustration of the difference between board cores.
A good analogy is the difference in power delivery and hence 0-60 times in cars that are naturally aspirated, and cars that use super-chargers or turbo-chargers. The acceleration in naturally aspirated cars is even, and would have the same line on a graph as an ollie with a bamboo core. Turbo charged engines have that pause before the power kicks in, then when the power kicks it occurs all at once (and you get thrown back in your seat).
