Pcie 6.0 will offer 64 gtps per track and will launch in 2021
Table of contents:
Although AMD has already implemented PCIe 4.0 on its range of Ryzen 3000 series processors and the latest graphics cards, Intel is still stuck on PCIe 3.0, having canceled its plans for PCIe 4.0 at Comet Lake. Meanwhile, PCI-SIG, which makes the PCIe specifications, today announced version 0.5 of the upcoming PCIe 6.0 specification, which has eight times the bandwidth of PCIe 3.0.
PCIe 6.0 makes the jump to an impressive 64 GTps per track
Although we have not yet seen products that support PCIe 5.0, PCI-SIG announced for the first time that it would introduce a PCIe 6.0 specification in October. The jump in bandwidth specification is not a surprise, as each new generation of PCIe doubles the bandwidth of the previous one. Where PCIe 3.0 has a bandwidth of 8 GTps per track, PCIe 4.0 doubles that figure to 16 GTps, and PCIe 5.0 jumps to 32 GTps. Logically, the PCIe 6.0 makes the jump to an impressive 64 GTps per track.
Those figures translate to about 8GBps per PCIe 6.0 track, which for a 16-track slot would equal almost 128GBps per slot. Consequently, it would not be a surprise if the eventual arrival of PCIe 6.0 devices meant that the days of full-length PCIe slots were numbered. The first sign of this was AMD's Radeon RX 5500 XT graphics card, which only needs 8 tracks thanks to PCIe 4.0 support.
According to PCI-SIG, the PCIe 6.0 specification is on its way to being released in 2021. However, that does not mean that we will see products with it in 2021; it just means that hardware vendors will start developing products to this standard.

The biggest areas that will benefit from faster PCIe, at least initially, are high-computing platforms such as artificial intelligence and machine learning. It is likely to be much longer before individual consumers begin to take advantage of increased bandwidth.
PCI-SIG will share more details at its next Developers Conference from June 3-4. We will keep you informed.
