PCIe is a communication bus normal that enables 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 known 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 absolutely backwards appropriate, so units designed for older PCIe variations will nonetheless work with the newer normal.
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.

What does this imply? For one, storage units will be anticipated to run at 2x the Learn/Write speeds of Gen 4.0, seemingly 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 functions.
This extra bandwidth additionally implies that units might be able to obtain the identical throughput whereas utilizing fewer lanes, thus liberating up the variety of lanes out there. For instance, a graphics card that used to require x16 bandwidth to run at full pace might now run on the similar pace with x8, making an extra 8 lanes out there.
When Will PCIe 5.0 Be Obtainable?
PCIe 5.0 is at present out there NOW on most Intel Z690 chipset motherboards, like these featured on our Raptor Z55. AMD has confirmed their subsequent Ryzen refresh out there later is 2022 will help 5.0 as effectively.
PCIe 5.0 Gadgets
As of this writing, there are not any 5.0 units at present out there…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 effectively it’s going to make the most of the extra bandwidth stays to be seen. Keep tuned for NVMe storage drives working on 5.0 coming quickly as effectively, hopefully later this yr.
