Regardless that gaming PCs have but to make the leap to the brand new PCIe 6.0 interface, work is already underway on not simply PCIe 7.0, however now additionally PCIe 8.0, which seems to be set to place present PC interfaces to disgrace. A 16x PCIe 8.0 slot will supply an infinite 1TB/s of bidirectional bandwidth, in accordance with the PCI Particular Curiosity Group (PCI-SIG). To place that determine into perspective, a 16x PCIe 4.0 interface, as utilized by the Nvidia GeForce RTX 4090, peaks at 64GB/s, which is simply 1/16 of the bandwidth of PCIe 8.0.
It may be a very long time earlier than we see any of the Nvidia gaming GPUs on our greatest graphics card shopping for information sporting high-speed PCIe 8.0 interfaces, after all, however the efficiency potential right here is immense. In reality, even a primary, single-lane PCIe 8.0 slot would supply as a lot bandwidth as a 16x PCIe 4.0 slot. Not solely that, however a 4x PCIe 8.0 connector, which may very well be used for an M.2 SSD slot, would supply a peak of 256GB/s of bandwidth, which means we may very well be SSDs that may learn at 120GB/s sooner or later, if you will discover large enough heatsinks for them, naturally.
Provided that the newest PC gaming {hardware} does not even use PCIe 6.0 but, nobody at PCI-SIG is speaking about gaming merchandise utilizing the brand new interface but. Let’s face it, not even the mighty Nvidia GeForce RTX 5090 is saturating the 16x PCIe 5.0 interface but. As a substitute, PCI-SIG is discussing PCIe 8.0 in relation to AI, quantum computing, and edge computing, citing hyperscale information facilities and navy/aerospace as markets that may profit from it.
Even these industries shall be ready some time for the primary PCIe 8.0 merchandise, as PCI-SIG says the spec will not be launched till 2028. Even then, it will likely be a number of years once more earlier than PCIe 8.0 makes it into gaming PCs – the bandwidth calls for merely aren’t wherever near that stage of efficiency in video games but.
PCI-SIG additionally says it is “reviewing new connector expertise” to assist PCIe 8.0, and that the brand new interface will proceed to keep up backward compatibility with gadgets primarily based on older PCIe generations. I nonetheless cannot recover from that 1TB/s bandwidth determine, although. I am nonetheless amazed you can get 1TB/s of reminiscence bandwidth from among the newest GPUs, because of super-wide interfaces and extremely quick reminiscence, however the concept you would get the identical bandwidth from a motherboard slot is frankly ridiculous.
Within the meantime, PCIe 5.0 is a lot quick sufficient for any gamer’s wants, so take a look at our information to purchasing the most effective gaming motherboard in case you’re considering of upgrading, in addition to our greatest gaming SSD information, which incorporates a number of of the newest super-fast PCIe 5.0 drives.
You can even observe us on Google Information for day by day PC video games information, evaluations, and guides. We even have a vibrant neighborhood Discord server, the place you’ll be able to chat about this story with members of the group and fellow readers.
