The members of the PCI-SIG have received the documentation of the PCIe 6.0 standard which reaches its version 0.7, is expected to be ready for next year 2021 as we already discussed here. This new version of PCIe 6.0 features doubling the speed of PCIe 5.0 to 64 GT / s , this increase would be four times more than the PCIe 4.0 that is being introduced in the market little by little and up to 8 times greater than the PCIe 3.0 that currently predominates in the market.

In addition to this improved speed, changed to PAM4 encoding or pulse width modulation with 4 levels (Pulse Amplitude Modulation With 4 slight), the introduction of Low Latency Forward Error Correction (FEC) with mechanisms additional for the improvement of the bandwidth efficiency and of course compatibility with all the previous versions of PCIe .

The PCI-SIG organization has considerably reduced the time completion of the new PCIe standards, remember that PCIe 3.0 was released in 2010 and it took 7 years until 4.0 finished , but only 2 years later, in 2019, I end the PCIe 5.0 and now It is expected that it will take only two more years to reach 6.0 . The PCI-SIG has been very happy to be able to offer these new improvements in much less time, improvements that could benefit especially large companies, such as network cards) Gb / s.
