Torx head sizes are described using the capital letter "T" followed by a number ranging from T1 to T100.
Notably, the greatest improvement is the close elimination of hassle of 'cam out' occurring. The hexalobular design of the Torx socket has allowed force to be closer to a 90 degree angle in each corner, meaning it's stronger and more resistant to rounding.
Phillips screws improve on this design by restricting movement in two dimensions and force the screwdriver to always be in the center, but they slip easily and wear quickly. Torx are superior because they fit much more "snugly", though at the (minor) cost of being less forgiving of using the wrong size of screwdriver.
