Why still no PCIe 4.0 for Intel?

As title.
It seems that we will not see PCIe 4.0 this year and even next year.

Why?
I know that PCIe is not really needed now but no one upgrade his PC every year so having it now could be a good feature proof feature.

because they are producing new cpu with always an updated price?
and most importantly why PCIe 4.0 will last so few?

it's the first time in PCIe history that we see a PCIe lasting only two years.

Hopefully big Navi will make use of PCI-E 4.0. They would need like a 2080 ti and half to saturate 3.0? Someone had to do it first. I don't see why Intel won't have it in their next lineup. Could be argued as a gimmick atm. That actually hurts AMD in some ways, I see people asking can a Radeon 5700 XT run on my Pci 3.0 Slot? I wonder how many people don't ask and assume it won't. Maybe those same people will buy 570 Mobos who knows.

as I said, most people buy a CPU and live with it for four or five years upgrading the GPU only in the mean time.

buying today a PCIe 3.0 CPU is a really bad bet for those kind of people. can't understand why Intel isn't jumping to the PCIe 4.0 too for its newer cpus.

Because Intel is behind the curve, sat on their ass making huge profits for about a decade with mediocre improvements without competition. I think PCIe 4 for the chipset is a big thing for expandability options. Yep, for me, a new motherboard for my main system will have to have PCIe 4 -> no Intel at this time. Now I just bought an ITX MSI B450 motherboard but that is for Ryzen 2700 I have laying around which is still very useful. For my main or top system upgrade -> PCIe 4 in the future. Hell my X370 motherboard was doing PCIe 4 flawlessly until AMD mandated pretty much only X570 could have that feature. All tests I've done Games, synthetics, video encoding GPU and then CPU showed no difference in performance except for 3dMark PCIe test. SSDs has a pretty good size jump but it is the rest of the board that gets double the bandwidth capability that is probably the biggest advantage.

Boom. That's it in the nutshell. Why bother for real. This is a benchmark I did today using 2 of my systems. One Xeon E5-2690 stock at 3.3 ghz and one i9-9900k at 5.0 ghz

But it feels like I am comparing this to 8700k when it comes to fps.


Intel has had amazing chips, but why spend millions to improve something that no one is competing with. AMD sat on their ass longer than Intel, but Intel capitalized on it. They literally refreshed their flagship CPU since 4790k, into 6700k, then 7700k, and only 8700k was new and different, but only about 10-12 fps difference. I know, since I had 4790k and 8700k, and did comparisons.

Intel has no reason to implement PCI-e 4.0 on their mainstream platform yet. It makes much more sense to bring it to HEDT and I expect them to do that sooner rather than later. We'll probably see it whenever Intel moves off 14nm. Graphics cards don't saturate PCI-e 3.0. The only thing PCI-e 4.0 aids at the moment is storage and SATA transfer speeds are plenty fast for the vast majority of users. The only people who need PCI-e 4.0 are users who benefit from the additional storage performance. That's an extreme minority of users.
