PCI-SIG® Releases PCIe® 6.0 Specification
PCI-SIG® announced the official release of the PCIe 6.0 specification, reaching 64 GT/s transfer speeds, doubling PCIe 5.0’s data rate, and providing low latency and reduced bandwidth overhead.
Features include:
- 64 GT/s raw data rate and up to 256 GB/s via x16 configuration
- Pulse Amplitude Modulation with 4 levels signaling, leveraging PAM4 already available
- Lightweight Forward Error Correct (FEC) and Cyclic Redundancy Check (CRC) to mitigate the bit error rate increase associated with PAM4 signaling
- Flit (flow control unit) based encoding supports PAM4 modulation and enables more than double the bandwidth gain
- Updated Packet layout used in Flit Mode to provide additional functionality and simplify processing
- Backwards compatibility with all previous generations of PCIe technology
