@nblr @manawyrm @ann3nova yeah, I mean, my workstation has 2.5-GBase-T on motherboard, but I do have an Intel X520-2 for talking to SDRs, which I'm currently not using.
From knowing people who used that specific card in battery-powered devices, I do get the feeling that card specifically isn't the most energy-efficient end-to-end, but I haven't done a loopback test (X520 port A - SFP+ - 10-GBase-SR - SFP+ - port B, all artificially set to 1000Base speed) with a power meter for the whole system.

@funkylab @nblr @ann3nova If energy saving is the target, there are some fancy very new chips on the market now from Realtek, etc., which are much much more energy efficient. I still like to have my good Mellanox/Nvidia cards so I get their awesome driver quality (instead of the crap Intel/Broadcom/Chelsio/etc. are shipping).
