GMA HD2 improves transcendental math hardware over HD1, and expands the register file. The 2000-series IGP has 6 execution units, while the 3000 has 12. Currently, 3000-series IGP's are reserved for K-series processors (the P67 performance-oriented chipset cannot make use of the IGP, and requires a discrete graphics adapter). The IGP has limited locking on its clock -- the H67 chipset can control IGP multipliers. | GMA HD2 improves transcendental math hardware over HD1, and expands the register file.
