The EP-4T2A3 is based on the Intel 850 chipset, an AGPset offering a 400MHz Bus Clock, supporting a single Socket 478 Pentium 4 processor. The AGP Slot is compatible with any AGP compliant adapter providing an immediate doubling (or quadruple) in the maximum available 2D/3D Graphics Bandwidth without reducing performance of other PCI cards. AGP Technology also allows Virtual Reality applications to use as much texture buffer space as they need without expensive card or hardware upgrades.
