Better safe than sorry. Would be sad if inactive PCI-E 4.0 added additional cost for the chipset.

Great platform that will be. Chipset that support pcie 4.0 but cannot use and an 300w tdp 10core already outdated. Intel these days...

When I was little I always ran against older kids from other blocks, and I won many times.
They got to the point :
Yeah, tomorrow, I'll bring my special running shoes and I will win, because you are a cheater.
Talking about special chipset that will make everything ok and forgotten.
Intel, what are smoking, buddy?

well the signal wasn't completely clean in Zen 2 so i don't see the excuse flying here.
though not surprised intel can't get a first generation gen 4 controller right, they couldn't with gen 3.

Ok, maybe in 2028 we can see any improvement using pci expresd 4.0 over 3.0 on new top high end videocard

Is not about videocards, but about lines availability.
If pciEx4 is double fast than 3, i can use 8 line instead of 16 on a pci express 4.0 video card, get the performance of 3.0 at 16x. Use the free 8 lines for something else ( another nvme for example, a fast one )

Haha, this is ridiculous. Though in a sense understandable because apparently ASMedia failed at making a chipset for Zen2, and thus we still haven't got anything but the partially flawed X570 (a variation of the CPU io chip itself). Seems like Intel's billion dollars R&D had no better luck.

Just wait until nVidia announces their new generation Ampere, or 3000 series or whatever the name is and it will be PCIe 4.0 cards.
And AMD's RDNA(2) products will obviously be 4.0 as well.
No-one in their right minds would buy Z490 to willingly give up performance on their shiny new latest generation GPUs... especially considering that AMD's next gen with even more IPC and probably more clocks as well is basically just 6-7 months away from release.
How could they (Intel) screw this up so badly !?

maybe at gen 5.0 we will finally have enough lanes that we can spare some for 10g ethernet, and phones will be doing 50gbit lifi by then

Q: "Do you support PCIe4.x yet?"
Intel: "Yes, we have motherboards right now that support PCIe4.x, but due to technical reasons they only function as PCIe.3x mboards at present."
Q: "So if you put a PCIe4.x device in such a slot, it will function only as a PCIe3.x device"?
Intel: "Yes, that's our PCIe4.x support at present, you are correct."
Reminds me of nVidia in the past: "Oh, yes, we support that feature in this product/drivers and always have--it's just that we haven't turned it on, yet"....;)
EDIT: Slightly different take here:

This is a huge middle finger to the board partners.
Intel tells them to design for PCIe 4, so they use money and time to design the motherboard to meet this standart, Instead of just copy paste from previous gen, but when the Chipset trays arrive and it is time to solder it onto the board, it does not work.
That is how i understand it atleast.
Hope somebody gets fired for this huge fail.

wow more incompetence from Intel, I'm shocked. The company needs a new CEO to bad Lisa Su has a job.

Intel can´t get anything right nowadays... What´s happening inside the company???
