The Futuremark 3DMark06 benchmark is useful for comparing performance between similarly equipped systems. This multi-threaded, "gaming related" DirectX metric consists of different 3D scenes that are generated with software and hardware GPU renderers, which is also dependant on the host CPU's performance. In these tests, calculations that are normally reserved for a 3D accelerator are sent to the central processor.
The T400s’ integrated graphics is definitely the weakest link in the machine. This led to low overall scores in the 3DMark06 benchmark. Compared to the Lenovo G530 which also has Intel integrated graphics, the T400s fared slightly better. 3DMark06's GPU rendering tests utilize a mix of SM2.0, SM3.0, and HDR techniques and effects. Here again, the T400s’ integrated graphics holds the machine back.
The T400s achieves a mid-range score on the 3DMark06 CPU component.
