What’s PCIe 5.0 – Availability and Advantages

PCIe is a communication bus customary 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 suitable, so gadgets designed for older PCIe variations will nonetheless work with the newer customary.

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 isn’t 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 might 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 signifies 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 could now run on the similar velocity with x8, making a further 8 lanes accessible.

When Will PCIe 5.0 Be Obtainable?

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 assist 5.0 as properly.

Samsung M.2 SSD

PCIe 5.0 Units

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