Silly question about NVMe drives.

[RollTime]

So as I understand it, NVMe drives use PCIe lanes to be so fast. My question is how this affects other PCIe devices. If my CPU has 16 PCIe lanes and an NVMe drive uses 4, that leaves me with 8 lanes for the GPU and... 4 left over? Are they just unused? Can someone please explain?

why do people ALWAYS forget that the mainboard chipset can provide additional lanes.

Depends on if the drive is connected to the chipset's PCI-e lanes or the CPU PCI-e lanes.

The CPU has of course only 16, but on current Intel mainstream platforms the chipset offers another 20 I think.

How is he supposed to know this? Do you get born with that knowledge?

It's amazing how many people on the Internet have this expectation thought they're usually more rude about than this person was.

i actually did not even mean to be rude - sorry if it sounded like this

 

but seriously - i've read this question so many times now.

i guess it needs to be communicated more often and more clearly.

You don't need to apologize to me. Apologize to OP.

 

I do see where your frustration comes from though. It has to be understood though that not everybody knows everything and those who don't know what you know can only help it if you teach them. That's how I've learned a lot of things that revolve around my interests from people on the forum teaching me or correcting me.

 

It does get annoying to hear the same problem again and again but that can't be helped, at least they know what an NVMe drive even is to begin with. I'm sitting in a pizza shop right now and i guarantee if I went around asking that question not a single person would be able to answer what that is. Most people in my home town only know how to turn their computers on let alone open it up and name every piece of hardware they're looking at so asking about PCI_e lanes is a fairly advanced question most people wouldn't even need to know or care to know about.

Just make a big sticky post and problem solved (well at least partially)

You mean one of those big sticky posts that no one reads?

Agreed. Is there a site you recommend where I can learn about this?

At least you have an excuse to act like that LOL

websites like tomshardware, anandtech, gamers nexus, linus tech shoud have an article on that. Check CPU vs motherboard lanes etc
