They're not the same.
CDI = Capacitive Discharge Ignition. The ignitor steps up the voltage to several hundred volts, charges a capacitor, than discharges that into the primary of the ignition coil. The result is a seriously intense short duration spark. Most performance ignitions are CDI.
Transistor ignitions are far simpler. They just replace the breaker points with a transistor (or SCR, or MOSFET). Most ignitions in the '80s and '90s used a similar system integrated into an ignitor (like the 2nd gens).
