VIA shows off PT880 chipset, Athlon 64 mobos
We have a few remaining bits from Quakecon to share with you yet. Among them is this shot of VIA's working demo of the PT880 chipset, which features VIA's QBM memory scheme.
QBM provides the equivalent of dual memory channels on a single DIMM, so a single QBM module at 400MHz can achieve peak throughputs of 6.4GB/s. The PT880 also supports more traditional dual-channel memory configs using dual banks of DDR400 DIMMs. What's more, the chipset can support dual banks of QBM DIMMs. If I'm tallying right, that config should yield 12.8GB/s of memory bandwidth. No doubt if VIA has a working reference board, the final silicon should be a matter weeks away, at most.
Also on displaythough not in operation, save one demo boxwere K8T800-based motherboards for 754-pin Athlon 64 chips. Among VIA's design wins were boards from Abit, Asus, Biostar, Soyo, Epox, Jetway, and FIC.
