As this is right at the corner, I'll hold a bit more for motherboards to come out with this.
Also DDR4 prices are ludicrous.
They sure are going fast this time, working on 5.0 already.

When will a motherboard come with PCI-4.0?
When will a graphics card come with PCI-4.0?

For users with only 1 GPU this shouldn't make any difference at all unless we are talking about SLI and CrossFire. People are still using PCI-E 2.0 without issues. I don't think 3.0 will be saturated by 1 GPU any time soon.

This could be the start of something big. Imagine a motherboard with only an entry level number of pci 4.0 lanes which could easily have 4 or even 6 pci 4.0 x2 m.2 ports which could power all pci 3.0 x4 m.2 drives at max bandwidth and still have 16x 4.0 lanes for headroom for years for graphics cards and any other extra stuff a motherboarf could want. Even a board with only 28 lanes could have that, it could even do sli with 4.0 x8/x8 while still power all those drives.

Here's what I don't get:
What exactly is going to take advantage of this, even in the server market? To my understanding, x1 slots still aren't going to be fast enough to handle fiber optic NICs; they're currently using x4 or x8 slots. Same goes for enterprise SSDs. We might as well just skip straight to 5.0.
USB 3.2 seems to be the only practical reason to need the available bandwidth, but, I doubt we're going to see any USB 3.2 devices that will actually saturate the bandwidth by the time PCIe 5.0 comes out.
Anyway, correct me if I'm wrong but will a PCIe 5.0 x1 slot be as fast as a 1.0 x16 slot?
Does it matter? To my knowledge, there are no GPUs that will saturate 3.0 at x8 (except maybe an overclocked 1080Ti under specific workloads).

I think more bandwidth per lane is awesome, considering that then you need less lanes for each device to have the same performance.
Currently you have to spend a small fortune if you want all the lanes, so having faster lanes might help on motherboards+CPU combos lacking in numbers.

and that's where NVIDIA's VOLTA and PCI express 4.0 (standardized) .......and GDDR6 (Hynix) will stand on 2018 upto 2021
PRETTY SURE that i have been patient with my upgrades....

Some 8core cpu (icelake or tigerlake) with ddr5 mobo + pcie 4.0 in 2019 sounds good 😀
