    Looks like PCIe Gen 4 is going to be one of the shorter lived generations of the standard.

    Yup. Might hold off on a complete system upgrade until 2021. Have an 8700k and 2080ti, so I should be good unless I get antsy :).

    Honestly, the way I see it is that these fancy new PCIe generations don't matter much.

    Today, the only devices I have that even use Gen 3 are my GPU and NVMe drives. Everything else is Gen 1 or Gen 2.

    So the way I see it is, when these standards first launch, they will be non-issues, until way down the line.

    Are GPUs even fully utilizing the bandwidth of PCIe 3.0 x16? Last I heard they were still well below that spec, but that was before this current generation of cards. EDIT: There's a little bit of difference. At least when paired with an RTX 2080 Ti

    PCIe 4 is currently only useful for NVME drives. And even then that speed is only visible in enterprise/niece use cases. And benchmark epeen size.

    They might not matter to the end points, but it does allow for more bandwidth between the CPU and chipset, which in turn allows the chipset to handle more end points. Of course getting the OEM to design things that way is another matter.

    Agreed.

    That is the biggest benefit for now.

    I'm still disappointed AMD decided to keep only 4x lanes between the CPU and the x570 chipset. Sure that is double the bandwidth of their previous designs with Gen 3, but they also have the ability to use 40 lanes off of the chipset. That's a lot of lanes sharing that bandwidth.

    I'm sure motherboard makers had something to say about adding 8+ more high speed lines and the necessary noise mitigation required for them between the CPU and chipset on already crowded boards.

    Wake me up when GPU's use PCI Express 5.0, until then, its all fluff.

    Only thing that sticks out to me is that there's kind of a more concrete timeline there of when DDR5 RAM is going to be in use.

    I was going to upgrade to the 3rd gen Ryzen if the IPC increase is good then basically hold off onto a platform using DDR5 is out. Now I know it's a good thing I held off on that additional 32GB of DDR4.
