What’s PCIe 5.0 – Availability and Advantages

PCIe is a communication bus commonplace that permits numerous PC parts – graphics card, storage, add-in playing cards, and so forth. – to speak with one another. Specs and nomenclature are decided by a collective referred to as the PCI Particular Curiosity Floor (PCI-SIG), with every new iteration a brand new “Technology,” thus PCIe 2.0, 3.0, 4.0, 5.0, and so forth. Like earlier variations earlier than it, 5.0 is totally backwards appropriate, so gadgets designed for older PCIe variations will nonetheless work with the newer commonplace.

5.0 vs 4.0 – What are the Advantages?

Every new model of PCIe has successfully doubled the bandwidth of the prior model, and Gen 5.0 is not any exception.

PCI-Categorical 5.0 vs. 4.0 Speeds

PCIe 4.0 PCIe 5.0
x1 Bandwidth 2 GB/s 4 GB/s
x2 Bandwidth 4 GB/s 8 GB/s
x4 Bandwidth 8 GB/s 16 GB/s
x8 Bandwidth 16 GB/s 32 GB/s
x16 Bandwidth 32 GB/s 64 GB/s


What does this imply? For one, storage gadgets could be anticipated to run at 2x the Learn/Write speeds of Gen 4.0, probably round 13,000 -14,000 MB/s. That’s a reasonably eye-popping quantity, particularly contemplating how briskly SATA SSD’s at 500 MB/s nonetheless really feel to most customers and purposes.

This extra bandwidth additionally implies that gadgets could possibly obtain the identical throughput whereas utilizing fewer lanes, thus releasing up the variety of lanes accessible. For instance, a graphics card that used to require x16 bandwidth to run at full velocity might now run on the identical velocity with x8, making a further 8 lanes accessible.

When Will PCIe 5.0 Be Accessible?

PCIe 5.0 is at present accessible NOW on most Intel Z690 chipset motherboards, like these featured on our Raptor Z55. AMD has confirmed their subsequent Ryzen refresh accessible later is 2022 will help 5.0 as nicely.

Samsung M.2 SSD

PCIe 5.0 Units

As of this writing, there aren’t any 5.0 gadgets at present accessible…however they’re coming. Rumor has it that NVIDIA’s latest Geforce RTX 4000 collection will make the most of 5.0, though to what extent and the way nicely it can make the most of the extra bandwidth stays to be seen. Keep tuned for NVMe storage drives working on 5.0 coming quickly as nicely, hopefully later this yr.
