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.

      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.

    Why are they still bolting out new versions, despite v5 already having issues with proximity to the CPU (too high frequency), efficiency and heat dissipation issues to a point the mainboard itself needs fans/fins? Shouldn’t they add some kind of throtling to the protocol, because you don’t always need full speed and climate crysis and all?

    At this point, a PCIe 7 mainboard would need to be photonic only to work at all. Or only on SOC designs, but that’s contrary to the usecase of PCIe.
