Rambus already has PCIe 5.0 interfaces and controllers ready for the professional segment

Announced by Rambus that they have already developed the first PCIe 5.0 interfaces and controllers for the professional segment.

The first to implement the new PCIe 4.0 interface is AMD. This connection interface does not offer significant improvements over PCIe 3.0. This standard will have a very short life due to, among others, the PCIe 5.0 that will implement important improvements. Its release is expected in 2021 in the business environment and is vital for Intel and the CXL technology, which works under PCIe 5.0.

Compute Express Link (CXL) is an open industry standard interconnect that provides high bandwidth, low latency connectivity between host processors, systems, and devices such as acceleration cards, memory buffers, and smart I / O devices.

Rambus announces that it has already developed the PCIe 5.0 interface

After a lot of research and development work Rambus announces that it already has drivers and interfaces ready for this standard. This allows future manufacturers to start prototyping products.

The company indicates that they are now starting to work on chips based on 7nm lithography. The biggest problem with this new interface is the heat generated by the controller. As is the case today with AMD chipsets with support for PCIe 4.0, which require a fan due to the heat generated.

PCIe 5.0 offers us a bandwidth of 32Gb / s per channel with a typical connection of sixteen channels. So all the channels offer us 512Gb / s or 32GB / s of transfer. Rambus has targeted it to the professional segment, so the first solutions based on this technology could be based on artificial intelligence, high-performance computing, storage, and 400 Gigabit Ethernet networking equipment.

It is unknown when the commercial version of PCIe 5.0 technology will be released, but it is possible that it will be in 2022 at the earliest. It will be a matter of having some patience.
