I9 11900k Lanes

I want to upgrade my system to an i911900k and appropriate motherboard, I require the following components to be connected,
• X1 NVME (Samsung 970 Evo)
• X1 3090FE
• X1 NIC (x540)

4 lanes for the NVME
16 for the GPU
4 or 8 (not 100% sure) for the NIC

So that could be 24 minimum and 28 lanes maximum

Do I have enough PCI-E lanes to run all this?

Thanks in advance.

What kinda mainboard [size / spec], are you looking to use?
The i9s PCIe bank, will accommodate for an 4.0 NVMe + a x16 lane [aka, the GPU]
At a minimum, a 540 NIC unless I’m confirmed wrong, would need a x8 lane to run

I don’t have a motherboard yet, I am trying to find out this information before purchasing anything.

NVME is 4 lanes
3090 is 16 lanes
NIC is 8 lanes

So you need a total of 28 available lanes

The i9-11900k only has 20 available. Unfortunately while you have the bandwidth to run the network card because its only PCIe 2.1 it will not be able to use the full bandwidth of the 4.0 PCIe on the CPU.

I agree with GoldenAngel,

11900k has 20 PCIE 4 lanes.
Look at the motherboard layout to see what you get.
With the Z590 AORUS Elite for exemple
You get 16 lanes for the graphic and 4 lanes for the nvme drive. (PCIE4)
The rest of the pcie slot run as pcie3

Full-size ATX

Would the 5950x be a better option?

Not entirely sure.

Look at the transfer speed.
PCIE4x8 = PCIE3x16…
So you can run basicaly any GC in a PCIE4x8 without noticing frame drop.
May be not with the 3090.
But my point is that with your NIC you need to check if PCIE3 would be enough.
I think so.

Don’t you also get lanes from the chipset on the motherboard?

Yes but not just because of the number PCIe lanes, but because its a better fundamental CPU with 16c/32t vs 8c/16t of the i9.

The AMD x570 has 36 usable PCIe lanes
The Intel Z590 only 24 lanes

Yes x570 has some PCIe 4.0 lanes, the Z590 is PCIe 3.0.

Intel is behind the curve on cores, threads, instructions per clock, and transport bandwidth.

You are 100% right.
But you can buy intel basically anywhere.
And It’s cheaper than AMD.

Ryzen 5000 availability is better now but still compare to intel CPU…

@noobftw You’ve to get you pro and con. :wink:
Good luck !

I think I’m going to have to go AMD this time. Is it worth waiting on anything new to be released soon?

Always and never, there will always be new gear out in a month, 6 months, next year that is better than what you can get today, so really it depends on what you need.

If you NEED a new system today, its not worth waiting. If you have a last gen top end system its probably worth waiting.

That I’d treat, as an on-hold activity – since we’d need affirmation, that multiple vendors are ready to entertain supply / viable selection [DDR5 / Mainboards / new socket CPUs]… been a while, since this much of a collective hardware change

Nah not really. The X3D parts are socket compatible and coming early next year.

If you want a 5950x, I can make you a deal on one? That’s assuming you live in the UK
:smiley:

I’m UK based. and interested?

id suggest the intel x550 instead of x540. you can usually get them around $100 if you shop carefully

I already have it, had it a while now, got a great deal on it, which is why i chose it over the 550.
