Presumably because most (all? I didn't check) of the geometry is
stored in display lists.  These can be stored on-card and eliminate
the need for per-frame vertex transfers across the AGP bus.  In modern
hardware bus bandwidth, and not processing power is the primary
limitter of 3D performance.

It's worth pointing out for Linux (and BSD) folks, though, that the
DRI drivers for the Radeon don't yet support the on-card GPU.  All
vertex transformations are still done in the CPU; the graphics
hardware is used for texturing only.  Hopefully this will change soon.
