For gaming I would consider that the Turion is s direct descendant of the Athlon XP which argualbly is superior to any of Intel's chips for gaming, and that the Pentium M is a modified Pentium 3.
The Pentium M represents a radical departure for Intel, as it is not a low-power version of the desktop-oriented Pentium 4, but instead a heavily modified version of the Pentium III Tualatin design (itself based on the Pentium Pro core design).
