The Intera PowerStation delivers maximized system performance through its high-bandwidth interfaces, such as dual-channel DDR2 main memory, 1066 MHz system bus, PCI Express graphics and I/O architecture, and Hi-Speed USB 2.0 connectivity. PCI Express architecture enables increased bidirectional bandwidth to the graphics and I/O interfaces. With a 500 MB/s concurrent data transfer rate, it more than triples the I/O bandwidth of traditional PCI architecture. And with 4 GB/s per direction PCI Express graphics capability, it provides up to four times the graphics bandwidth of previous high-performance graphics interfaces. The Intel^® 965G Express Chipset’s high-performance architecture delivers additional system-level performance via enhanced memory pipelining that enables a higher utilization of each memory channel, improving data access. To support the increased graphics requirements and I/O bandwidth, the Intel^® 965G Express Chipset incorporates a new Memory Controller Hub (MCH) backbone architecture.

This new design includes wider internal data busses that support dual-channel DDR2 memory technology at 800 MHz of peak memory bandwidth, for improved platform performance. The new architecture also supports both asynchronous and true isochronous data traffic, with dedicated internal pipelines and specialized arbitration. In addition, the Intel 965G MCH has improved electricals with optimized ball-out for better latency with an additional bypass enabled. These enhancements enable PowerStation to take full advantage of the performance of these new high-speed interfaces.
