AGP can do both. Every AGP compliant device has to support the System RAM -> video RAM part. The other one is optional. Optional not only in the graphics card but in the northbridge, so there are some cheap chipsets that don't support it. This lead to many card manufacturers not supporting it in their cards and drivers. Highend graphics cards like the Wildcat support it.
