Minimum CPU spec to max out 40GbE and 10GbE dual 10GbE simultaneously? (alien.top)

I'm thinking of setting up a file server that just functions as a file server and has three NICs:

- 10GbE NIC

- 40GbE NIC

- 1GbE NIC

If I am going to max out these connections simultaneously how low can I go in terms of CPU power?

Can I do this with a dual core Pentium? What about a i3-4350?

First at all you need to look at L3 cache speed of your CPU.

Second on memory bandwich.

A dual core will definitely not be enough, alas you need SMB multichannel working on both sides for this to work.

You’ll definitely need something with fast PCIe lanes for NVMe. Something with either PCIe 4.0 x4 coupled with a very fast SSD, or something with a lot of PCIe 3.0 lanes.
