Bike News published an explainer on the structural difference between "opposed-piston" and "pin-slide" hydraulic disc brake calipers. Opposed calipers fix pistons on both sides of the rotor, while pin-slide calipers use a single piston with a sliding mount so both pads clamp evenly, and the piece notes that braking power differences mainly come down to rotor diameter and pad area rather than caliper type.

You'll never find this on a spec sheet, but it's the good stuff. Opposed-piston calipers transmit clamping force directly, while pin-slide calipers use reaction force to press both pads evenly. The point that braking power comes down to rotor diameter and pad area more than caliper type really clicks once you compare it against older models.
