The Atom does cnot process graphics per say. Tegra is a graphics chip ARM processor designed for handheld devices as stated above. Ion chipset is decent in the performance range but it is only DX10 capable and the Tegra 2 is SUPPOSED to be better with DX11. Most major brands will probably be using the chip for tablets shortly. It (Tegra 1) is already used in smartphones and the Microcrap Zune HD.
