Just wanting to make 100 Percent SURE this mobo has Pcie 5.0 for Video Card and M.2 is also pcie 5.0

1 x PCI Express x16 slot (PCIEX16), integrated in the CPU:
AMD Ryzen™ 9000/7000 Series Processors support PCIe 5.0 x16 mode

1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 25110/22110/2580/2280 SSDs:
AMD Ryzen™ 9000/7000 Series Processors support PCIe 5.0 x4/x2 SSDs

im taking it in simple terms, YES..

What I am sure he is saying is it mostly depends on the CPU

AMD Ryzen™ 9000/7000 Series Processors( I would think also 8000 series, so if the board says yes, and you are running one of those types of CPUs then yes

ive got the 9800x3d cpu

 

[fightingfi]

I guess its a Yes........thanks , ive got the 9800x3d cpu not sure what and how the cpu has anything to do with my question about pcie 5 i guess i ddint or dont understand enough about technology as to why i come here for help.

The CPU is what controls the PCIe lanes, the motherboard is just an interface.

But yes, you'll have 1 PCIe 5.0 for the video card, 1 PCIe 5.0 for a NVME and there's another 1 PCIe 4.0 NVMe slot. Based on the Gigabyte website, you cannot use all 3 NVMe slots on the board, 2 is the maximum.

 

[fightingfi]

Will any lanes be shared?

will i lose any gpu 16x performance? if so how can i avoid it?

which 2 of the nvme can i use

 

[Izerous]

A 5090 is not bottlenecked by a 8x gen5. Talking 1-3 fps differences.

 

[JD]

No mention of lane sharing for the GPU.

You'll want to use the top and bottom NVMe slots:





You can only use them all if you put a x2 lane SSD in both of them. They share the x4 lane. I've never seen an x2 NVMe though.

The X870E chipset has more PCIe lanes and doesn't typically have this issue.
