Can someone explain me this?

Why are there motherboards with an interface of Pcie 5.0 x16 for the graphics cards, even tho there are no graphics cards that support an interface of Pcie 5.0 x16 at max, but only graphics cards with the interface support of 4.0 Pcie 4.0 x16?

Eventually PCIe 5.0 will be a thing graphics cards support. Motherboards are often first to make the move to a new standard, peripherals which support it come later.

It is just an interface, not just for a graphics card. While for gamers it'll usually have a GPU in it, you could put other devices there.

 

If the tech is ready, why not make the move anyway? Other things can move up when they're ready.

makes sense...

PCIE lanes can be used for more than GPU's. If you need a m.2 to PCIE lane, then you will be able to read and write speeds fairly fast.

When GPU's support PCIE gen 5 then they will be used for GPUs

is there a estimated time when Pcie 5.0 x16 graphics cards will come out? (does it make sence to pre upgrade now or buy a new motherboard later)

Because manufacturers are bored and decided to have a pissing contest

Probably next generation. Given we just had launches from red and green, could be another couple years off. Maybe they do a mid gen refresh and drop it in, but don't hold your breath for it.

They also added USB4 to motherboards when no device was capable.
But in the future there might.

Right now, the only card that might just exceed the buswidth of the PCIe 3 x16 interface is the RTX 4090, and we still have PCIe 4 x16 which is twice that of PCIe 3 x16. So, I guess we still have plenty of bandwidth left with PCIe 4 x16, there's absolutely no card now that can fully saturate that for a while yet, which makes PCIe 5 x16 rather pointless for now, though it does sound good on marketing slides.
