In this coding scheme every eight (uncoded) payload bits of data are replaced with 10 (encoded) bits of transmit data, causing a 20% overhead in the electrical bandwidth.

The advantage of this scheme (compared to other methods such as wait states or handshake-based transfer protocols) is that the latency of credit return does not affect performance, provided that the The PCI Special Interest Group has a timeline for the development of PCI Express standards.

The receiver sends a negative acknowledgement message (NAK) with the sequence-number of the invalid TLP, requesting re-transmission of all TLPs forward of that sequence-number.

Barring a persistent malfunction of the device or transmission medium, the link-layer presents a reliable connection to the transaction layer, since the transmission protocol ensures delivery of TLPs over an unreliable The newer, 64-bit PCI-X bus provides more bandwidth, but its greater width compounds some of PCI's other issues.

NVIDIA's bus data rate reaches with PCIe 2.0. Since the mid-2000s, computer motherboards have at least one PCIe slot for the graphics card. At the physical level, a link is composed of one or more lanes.

The ECN identifies Multicast errors and adds an MC Blocked TLP error to AER for reporting those errors. Where this specification 5 does not explicitly define PCI Express characteristics, the PCI Express Base Specification governs. Figure 2.
