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

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.

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 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

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.

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.

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.

What, you don't miss the days of motherboards with northbridge fans?

Its the server world that is demanding it. For most consumers 4.0 is more than enough, but servers are already maxing out 5.0 and will probably immediately max out 6.0 when devices actually become available.

I'd be down to have SoCs with PCIe.

Won't somebody please think of the shareholders

Eh, I buy on a 4-6 year cycle. Here's what I bought:

1. Phenom II x4 - ~2010
2. Ryzen 1700 - ~2017
3. Ryzen 5600 - ~2022/2023

So, ~7 years, then 5-6 years. I had my Phenom II in my NAS until I decided to move my 5600 to a SFF case and put my 1700 in as an upgrade (and it uses less power, so double win). Oh, and I still have that Phenom II and my wife's old 6300 just in case my kids need a PC (they currently use mine).

You really don't need a top of the line CPU for most things. If you go for something mid-range prioritizing cores over clock speed, it'll last a while.

I haven't had any PCIe bottlenecks, everything has been "fast enough," and I upgrade when the CPU starts bottlenecking things. In fact, my GPU still doesn't saturate PCIe 3, much less PCIe 5. So yeah, PCIe improvements aren't high on my personal list of requirements. I'd prefer lower power usage and smaller physical size.

I'm running a 4090 on PCIe 3. Apparently I'm only losing about 5% off the potential frame rate, which is barely noticeable.
