@stephenw10 said in Is my math correct about PCIe bandwidht and 10Gbps NICs ?:
Only if you are trying to use both ports at full duplex. Which very rarely happens IMO.
Thanks Stephen, I will get one of those.. 👍
I have an AMD B550 chipset, which the DMI connection (from chipset to CPU), is PCI 3.0 x4.
I have doing some math with that also, and even using a NVME PCI 3.0 and a few SATA drives, won't saturate that link with this NIC (single port).
I have also a NVME PCIe 4.0, but that is directly connected to the CPU, so no chipset lanes used here.
I will use it in my server, connect it directly to a USW-Enterprise-PoE-8 switch through a DAC cable since local users will be connecting to it using 2.5Gbps ports, and also some connections from the Internet.
