PCI Express is an industry-standard, high-performance, general-purpose serial I/O chip-to-chip and board-to-board interconnect providing a cost-effective, low-pin count interface offering maximum bandwidth per pin. Key features of the standard include:
- High bandwidth, point-to-point interconnect: I/O bandwidth scalable to 64GBps at a signaling rate of 8GHz
- Scalable bandwidth to match system requirements: supports multiple interconnect widths from 1-32 PCI Express lanes
- Built on top of existing PCI infrastructure: software compatible with existing OSs and device driver interfaces
- Supports unique, advanced features: power management, hot swap and hot plug, data integrity, advanced error logging, and reporting, QoS
