A few viewers have written in with various questions about dual-core versus quad-core, Cortex A9 versus A15, nvidia’s Tegra 3, and why relative performance between them is so different and seems to defy logic.

In this episode we’ll talk a little about cores, different architectures, and make some super-awesome car-analogies along the way to try to explain it all.

We’ll keep things high-level enough to keep the episode understandable, but will get into enough detail to keep things interesting — and you’ll find out why a 3-cylinder commuter car is sometimes more desirable than a high-end Italian sports car.
