At Intel’s Developer Conference (IDF) , Intel has showcased the next gen PCIe 4.0 for the sake of high bandwidth transfer over PCIe lanes for upcoming products related to networking and storage solutions.
Offering 2x the bandwidth for the former PCIe 3.0 , it will also sport 16GT/s than the traditional 8GT/s which implies that the bandwidth allowances will be the same as the former ones effectively as the number of lanes will reduce offering with more bandwidth, specifically the double for PCIe 16x lanes for GPUs and generic PCIe solutions.
Doubling the bandwidth will in turn allow much faster storage over PCIe allowing more faster graphics solutions as they can easily communicate over the PCIe bus.
For now we do not have any such roadmaps officially from Intel but PCIe will take it’s place in consumer and enterprise motherboards benefiting Intel solutions perform with more bandwidth using the PCIe lanes and for more information we would like to add more by showing you a image which you will find below of a Mellanox 100Gb network card implementing that servers will get huge benefits due to this change.
Also we see that PCI-SIG or the Peripheral Component Interconnect Special Interest Group is researching on the PCIe 5.0 lanes which is said to offer 4x the PCIe 3.0 and 2x the PCIe 4.0.
