What’s PCIe 5.0 – Availability and Advantages


PCIe is a communication bus commonplace that enables varied PC parts – graphics card, storage, add-in playing cards, and so on. – 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 on. Like earlier variations earlier than it, 5.0 is absolutely backwards appropriate, so units 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 units might be anticipated to run at 2x the Learn/Write speeds of Gen 4.0, doubtless round 13,000 -14,000 MB/s. That’s a fairly eye-popping quantity, particularly contemplating how briskly SATA SSD’s at 500 MB/s nonetheless really feel to most customers and functions.

This extra bandwidth additionally signifies that units might be able to obtain the identical throughput whereas utilizing fewer lanes, thus liberating up the variety of lanes obtainable. For instance, a graphics card that used to require x16 bandwidth to run at full velocity might now run on the similar velocity with x8, making a further 8 lanes obtainable.

When Will PCIe 5.0 Be Out there?

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

As of this writing, there aren’t any 5.0 units at the moment obtainable…however they’re coming. Rumor has it that NVIDIA’s latest Geforce RTX 4000 sequence will reap the benefits of 5.0, though to what extent and the way properly it can 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 12 months.
