Question When will Intel compatible PCIe 4.0 and 5.0 motherboards and components be available?

[anandtechreader]

Hi, we know that some current AMD based motherboards could be upgraded to PCIe 4.0. On the Intel side, when will PCIe 4.0 motherboards and components be available to purchase? Will those compatible with PCIe 5.0 be available a year after those PCIe 4.0 be available?

Current AMD boards can only have the slot nearest the CPU upgraded to PCIE4, if the vendors decide to do so.
The other slots are too far away from the CPU for the signaling to work properly.

My guess is that most vendors will want to sell you a new board instead.

The problem with PCIE4 and up is getting the signaling to travel properly on the board traces.

As to when the problems will all be ironed out? It's hard to say. I expect maybe 2021.

it wouldn't surprise me to see PCIE4 either skipped over or be short-lived.

Thanks. When they make brand new PCIe 4.0/5.0 motherboards, can they avoid this issue? So Intel platform is also suffering from this issue? Does that mean it is still worth to invest on currently available top of the line PCIe 3.0 components? I know that I will need 64GB or more RAM later but for the next 3 months or so, 32GB will be sufficient.

There is always an issue with signal strength over the traces on boards, or over cables.
This is why a USB cable can't be very long. The signal gets too weak.

9900K supports 128gb of ram*, but I'm not sure why you are connecting PCIE to ram?

*Using the new 32gb DDR4 modules.

If PCIE 4.0/5.0 components for Intel platform will be available 2nd half of this ear or earlier next year, I may not invest on DDR4 64GB or 128GB RAM.

Although a lot of people recommend G.Skill Trident Z RAM, I don't seem to have luck with their products. I have RMA their products twice already.

PCI-E speeds / generations doesn't have anything to do directly with the DRAM bus, that's a separate bus/pin fan-out, separate protocol, etc.

Although, PCI-E 5.0 boards may use DDR5, so there's that. Perhaps that's what you mean?

Wouldn't PCIe v4/v5 and DDR5 be available on the prosumer/professional hardware first?I don't see regular consumer equipment having them them for at least a year or two afterwards.

I just watched a video on the newly released standard for USB 4.0. I wonder how that will affect motherboards also. The USB 3 cables are thick enough as it is. Maybe they will get rid of all USB 2.0

I think instead of two USB 3.0 sockets they should just put a USB 3.0 Hub on the computer cases.

sockets.
