PCI SIG has revealed the final specifications of PCIe 4.0, which had already been leaked and that in 2019 we will see PCIe 5.0, which will double in bandwidth to PCIe 4.0.

We already have the definitive data on the new PCIe technology, which will arrive this next year on motherboards and with official support in certain families of processors. PCI SIG, the association responsible for defining and developing PCI and PCI Express communication technology, has published the final specifications of the new PCIe 4.0 standard in a v1.0. Currently, we are in the PCIe 3.0 that offers a bandwidth of 32GT / s (in its most recent version), a technology that was launched in 2010 and that has been with us for several years, just too many.

PCIe 4.0 will initially offer 64GT / s (64Gbps), which is double the bandwidth power of PCIe 3.0. Currently, PCIe 3.0 allows offering up to 75W, but in PCIe 4.0, 300W of power with peaks of 500W is offered, something that in many models (GTX 1060, GTX 1070 or RX 580), could mean the suppression of the power connectors, but be careful, this would limit or prevent overclocking on these graphics cards, since the power of this connector is finite.

The life of this connector will be shorter than PCIe 3.0, since it is expected that in 2019 PCIe 5.0 will arrive, which is still in development, being in version v0.3, but that by 2019 we will see the revision v1.0 .128. This position will offer a bandwidth of 128GT / s (4.0Gbps), a brutal bandwidth, which will be double that of PCIe XNUMX, in terms of bandwidth. Currently this expansion port is still a long way off, but it will be very important to develop faster and more efficient storage units or that graphics cards can communicate more efficiently with the processor.
