The EP-4BEAR is based on the Intel 845E chipset, an AGPset offering a 533MHz 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.
