ATI can make all of its chips AGP compliant using its well known Venetian Rialto chip that can translate PCIe instructions in AGP. Nvidia already dropped out from the AGP high end market as it didn’t want to release the Geforce 7800 GTX. Its fastest AGP card still available is the Geforce 6800 Ultra.
ATI won't release Radeon X1800 AGP

The Inquirer writes ATI will not release an AGP version of its Radeon X1800 (R520). The reason for this is because PCI Express is picking up fast so that demand for an AGP version of this card would be too low.
