I somehow missed that Intel went to 8 DMI links with the 500 chipsets already. Now with DMI 4.0 x8 thats comparable to 8x PCIe 4.0, quite some decent bandwidth for IO and storage, even for multiple chipset attached SSDs.

It seems like PCIe 5.0 doesn't add much challenge after PCIe 4.0, seeing how the 12th gen will already have it, so soon after the 10th gen failed to implement 4.0. I guess getting 4.0 to work (11th gen) already solved the problems and 5.0 needed nothing but fine-tuning.

Color me interested. I may upgrade a desktop next year and this is looking pretty good. I'll wait for the AMD response but it's all shaping up nicely on paper.

Feels like it's finally time to upgrade from X58, should be a significant jump, over 10 years.
Going from DDR3 to DDR5, from PCIe 2.0 to 5.0, 1Gbps LAN to 2.5 / 5 Gbps, Legacy BIOS to UEFI.
From SATA to NVMe, the SATA 3.0 ports (Marvell 9128 chip) on the Gigabyte X58A board aren't even capable of reaching 500 MB/s speeds, I have Samsung 830 and 860 EVO SSDs, the max read speed I got was 398 MB/s and write 241 MB/s.
And X58 obviously doesn't have Windows 11 support.

10th never failed to implement it - it was simply never part of the roadmap. And its true that from functional perspective there isnt much change between 4.0 and 5.0 HOWEVER, the validation of PHY in higher speed does present challenges - especially when there are NO Gen5.0 devices on the market...

Phison has already a pci-e 5.0 ssd controller ready 😉
ViperAnaf
They only started shipping the controllers few months ago... emphasis on controller... not actual gen5.0 devices were at the market... a device is more than just a "controller" you know...
nizzen
I wrote controller.... you know....
SSD= Controller + nand chips in "raid". Pretty much.
More nand chips in "raid" = higher bandwidth, if the controller is up to the task.
There will be pci-e ssd's almost "day 1" like the cheap slow pci-e 4.0 ssd's that came right after x570 launch
Even Marvell has pci-e 5.0 ssd controller ready.

Yeah, it was probably never part of the official roadmap, but Intel was planning it, nonetheless. Debating about whether they were only considering and testing possibilities or planning is just semantics in my opinion, especially seeing how so much of media PC tech content is future anticipation and expectations (including leaks and rumours). But sure, if we are extremely strict about it, you are correct.

Wish i had your discipline when it comes to upgrading.

"Day 1" of what, alder lake launch? Not going to be super useful, as Gen5 is only for the 16 graphics lanes, the 4 extra storage lanes are only Gen4. So unless you want to run your card on x8 (which is usually not that bad, to be honest), M.2 slots are likely to remain Gen4 for this generation.
If I were a motherboard maker, I would probably not bother with the complexity of the Gen5 routing and not offer a Gen5 M.2 slot, instead offer 1 Gen4 M.2 on the CPU, and 1-2 on the chipset, as before.
Depending on implementation, maybe you can actually get a PCIe card to put into a secondary slot.

X16 pci-e 5 OR 2x 8 pcie for gpu and Intel ssd

I hope its fast, so far i like it.
But i need a reason to upgrade my 5950x, if its really that fast like leaks, the single core is so much fast that the multicore score with less cores equals to 5950x with 16 core, that works for me
Ill take fast single core over multicore anyday
nizzen
I change my 5950x if it's faster in battlefield 2042

I would have upgraded sooner, my goal was to get a 10nm desktop as 14nm lasted for too long, but Intel kept delaying it. Cannon Lake was expected to be released in 2015/2016, but when it finally came in 2018, it was meant for mobile, same for Ice Lake and Tiger Lake. Crazy how much time has past since then, they are only now releasing a 10nm desktop CPU in 2021.
I wanted it to be a significant upgrade, so my next CPU needs to be at least 8 cores, as my i7-980 (32nm) already has 6 cores, going back to a 4c CPU would have felt like a downgrade, even if technically a newer generation is faster. Comet / Rocket Lake finally had 8 cores, but it's the last generation on DDR4 and I just had to skip it, don't want to be stuck with DDR4 for 10 years or however long until I will upgrade again.

Well, 5 is bigger than 4...

Man. My head was spinning just trying read the specifications of just the pci-e lanes.
I mean I guess I'll upgrade when the upgrading is just that "totally upgraded" before I do so.
Heck man. Pci-e lanes of third gen all the way to fifth on the same board.
Seems like mad corners where cut to be the first one on the street with the bigger stick. Then again the way I'm seeing it is the first one with the most obtuse stick trying to make sense of it.
Thank you Intel for the baseline. Now I'll just wait for that proverbial iron to come about in order to clean some of this stuff up.
Now now I'll wait for someone to mention the pci-e gen two to three iteration of boards previously (Asus). But this is different than those times/boards. So much going on on these motherboards...
