I can't see this really mattering to the mainstream gamer, we have the storage speeds we want and I don't think the graphics side of things will have a quantifiable performance gain so. oh well.
Understandable in all honesty and tbh it's not like we 'need' pcie4 for anything right now. SSD's aren't exactly slow on pcie3 and graphic cards aren't anywhere near needing the bandwidth just yet.
So it's really only 'fringe' cases that will make use of the bandwidth and most will likely do a full upgrade if that's the case anyway.
This is non-issue. The day you are really going to need the speed of PCIe gen 4 in consumer market, you will probably going to change socket and cpu. We are probably good for next 2-3 years.
The more you live, less you die. More you play, more you die. Isn't it great.
Given that it appears some manufacturers already have PCI-e5 devices in the works and that I upgraded only last year, I think I may well be able to bypass PCI-e4. My upgrade cycle is not a short one...
Is gen 4 just a click speed jump then? Surely any technical changes would need compatible silicon anyway?
My aim is to nurse my Haswell i5 through till passively cooled gen 4 is available for a sensible price. If that ckninsides with ddr5 so much the better as I can skip 4 then.
Understandable - any issues and it becomes a PR nightmare.
It would be nice if there was an unofficial unsupported means to enable PCIe 4 in some BIOSes of course, for the user to test themselves. But there isn't going to be a big gain in existing systems anyway. Once you are buying a new CPU, PCIe 4 Gfx Card and PCIe 4 M2 SSD, you might as well get the new mobo
So I read this as "on paper it will probably work but the QC was not set up to test for the more rigorous requirements of V4 so we can't take the risk of enabling it and therefore officially saying it should work and then possibly letting people down". That seem like a fair interpretation?
It isn't about QC, I think it is about dumb bunnies taking a punt on a cheap board hoping it should work rather than bothering to check compatibility against the test results, and then blaming AMD when their board turns out to be on the fail list.
If AMD say it doesn't work, and a BIOS happens to end up with an overclock feature for PCIe generation, then if it works you got lucky. I think that's just an easier sell.
I don't think it is reasonable to expect PCIe4 to work on a board that was never designed for it. But then I have yet to find a configurable TDP setting for my 2200G and that is supposed to be a supported feature of the chip so who knows what we end up with.

It looks to me like rather than saying "this isn't supported" and letting MB makers decide whether to turn on the function for adventurous types, they're saying "it won't work on most boards, so we aren't letting anyone use it". Which isn't an approach I agree with, I'd prefer they state it's unsupported but let users try their luck if they fancy. PCIe is backwards compatible anyway AFAIK, so it's admittedly a minor issue - a PCIe 4.0 GPU (when they launch) should still work on a 3.0 board
But not much recent history with ryzen (ISTR hearing of V56 getting flashed to V64, but nothing for CPUs). Right now it looks like dumbing down PCs to the detriment of intelligent users, but I'll happily revise my opinion if we get some 300 and 400 boards enabling the option
