PCIe 5.0 is just starting to arrive on new PCs, but version 6.0 is already there

to grow up / The ability of the PCIe 6.0 standard to work with all older versions of the device is a point of pride for PCI-SIG.

تمتلك PCI Special Interest Group (PCI-SIG) The latest version 6.0 of the PCI Express standard, the communication channel that allows all things inside your computer to communicate. The new version of the specification comes about three years after the end of the PCI Express 5.0 specification, and version 6.0 again doubles the PCIe router’s bandwidth from 32 GT/s (8GB/s in total, or 4GB/s in each direction) to 64GB in second (16 GB/s, or 8 GB/s in each direction). For a full 16-lane PCIe 6.0 connection, it’s up to 256GB/s in total bandwidth, compared to 32GB/s or 64GB/s for currently popular PCIe 3.0 and 4.0 connections.

Like previous PCIe versions, PCIe 6.0 will “interoperate and maintain backward compatibility” with all current PCIe versions, so a PCIe 4.0 GPU or SSD will continue to run in the PCIe 6.0 slot and vice versa. PCI-SIG prides itself on spec longevity Blog post By PCI-SIG Board Member Debendra Das Sharma: “A connection technology is considered successful if it can sustain three generations of bandwidth improvement over a decade. The PCIe architecture has gone far beyond that.”

PCI Express speeds compared. Note that these bandwidth numbers are bidirectional - if you're only sending or receiving data, you'll only have half the bandwidth. — to grow up / PCI Express speeds compared.

To increase its speeds, PCIe 6.0 uses a new type of signal called “Pulse Amplitude Modulation 4” (PAM4), which allows data to be transmitted faster than previous Non-Return-To-Zero (NRZ) signals at the expense of higher speeds. mistake percentage. To compensate, PCIe 6.0 includes technologies such as Forward Error Correction (FEC) for error correction and periodic redundancy check (CRC) for requesting retransmission of packets when errors cannot be corrected. PCI-SIG says that this set of technologies should catch all errors without adding latency to the connection.

Consumer systems are just beginning to support PCI Express 5.0 – Intel’s 12th-generation processors offer 16 PCIe 5.0 slots, and AMD plans to support PCIe 5.0 with the upcoming Zen 4 architecture and Ryzen 7000 series processors. Currently, PCIe 4.0 is the most popular version of the specs remaining for its drives. Advanced SSDs and current-generation GPUs, and most budget PCIe SSDs still use PCI Express 3.0, which older systems support more widely and are still fairly fast for most things. Detects PCI-SIG B PCIe 6.0 Frequently Asked Questions that the bandwidth of the new specification is not necessary for most consumer applications, and instead positions it as an upgrade to data centers and AI and machine learning systems.

PCI-SIG expects PCIe 6.0 products to reach the market within 12 to 18 months.
