The EP-4B2A2 is based on the Intel 845 chipset, an AGPset offering a 400MHz Bus Clock, supporting a single Socket 478 Pentium 4 processor. The AGP Slot is compatible with 1.5V AGP 4X-compliant adapters providing 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.
