Richard Solomon has heard the rumblings over the years. As vice president of PCI-SIG, the organization that controls the development of the PCI-Express
Is PCIe bandwidth a practical limitation at the moment for consumers? While it means you can use fewer lanes off the CPU there is no practical reason for consumers to be upgrading often enough to utilize faster generations. My impression was that the later generations are for server applications where more efficient use of PCIe lanes is a real benefit.
I was going to upgrade to a 6500XT to do some 1080 gaming but found out that I was on Gen3. AMD cheaped out and only put 4 lanes on the 6500XT, which meant not enough bandwidth. I don’t know how much of an outlier I am, as comparing which board has what generation is not easy.
Yeah that is an annoying thing that manufacturers have done. I bought a Gen 3 motherboard since everyone said that GPUs didn’t even utilize Gen 4 yet, but now the exact people that are wanting a budget card and motherboard combo have that incompatibility due to manufacturer cheapness.
I believe PCIe 4.0 wasnt that useful for big server farms, because network cards were already at 400gbps. Even at 100gbps networking, that’s only 2 ports.
PCIe 5.0 is only 1 port of 400gbps.
So PCIe 6.0 is the next actually big step for a lot of servers, so you can finally get dual 400gbps ports on 1 card
Not for consumers. Anything beyond PCIe5 is basically just server stuff. Frickle in handling, and expensive like sh-t. Just the same as with PCs: You don’t need a fat gaming PC for using office and browsing.
I think it opens up more lanes for more connectivity options. 2 gen 5 lanes instead of 4 gen 4 let’s you have two high performance nvme straight to the CPU instead of one.
PCIe is a bottleneck on large GPU systems. NVIDIA developed the NVLink protocol, which is way faster, to interconect GPUs and GPU systems on NDR400 Infiniband networks.
No, manufacturers had to redesign their mainboards vor v5, because the frequencies got so high they had to move components closer to the CPU. That and heat dissipation and efficiency issues in first generation, which are still somewhat present on current gen.
At least a few months ago, recommendation for new builds was to go with a v4 mainboard.

They working on pcie 7 yet I haven’t even found a pcie 5 device to use

That’s what kept me from purchasing one for my client. I wonder how much money they saved per unit doing that.
