AMD Updates AMD-8000 Chipset Family

Advanced Micro Devices today announced a new controller – or HyperTransport tunnel – to enable PCI-X 2.0 slots on the forthcoming servers and workstations based on AMD Opteron processors and AMD-8000 series core-logic.

PCI-X 2.0 – 533MHz PCI Technology

PCI-X 2.0 is a new, higher speed version of the conventional PCI standard, which supported signaling speeds up to 533MHz. Revision 1.0 of the PCI-X specification defined PCI-X 66 and PCI-X 133 devices that transferred data up to 133MHz, or over 1GB/s for a 64-bit device. The present revision adds two new speed grades: PCI-X 266 and PCI-X 533, offering up to 4.3GB/s of bandwidth, 32 times faster than the first generation of PCI. Another major feature of the PCI-X 2.0 specification is enhanced system reliability. ECC support has been added both for the header and payload, providing automatic single-bit error recovery and double-bit error detection. These new standards keep pace with upcoming advances in high-bandwidth business-critical applications such as Fibre Channel, RAID, networking, InfiniBand Architecture, SCSI, and iSCSI.

PCI-X 2.0 is built upon the same architecture, protocols, signals, and connector as traditional PCI. The reuse of many of the design elements from the conventional PCI and PCI-X1.0b standards eases design and implementation migration. Migration to PCI-X 266 and PCI-X 533 is further simplified by retaining hardware and software compatibility with previous generations of PCI and PCI-X. As a result, new designs can immediately connect with hundreds of PCI and PCI-X products that are currently available. The combination of backwards compatibility and ease of migration provides investment protection for customers, developers, and manufacturers of existing PCI and PCI-X technologies as they migrate to PCI-X 266 and PCI-X 533.
