I don’t remember the exact issues, but I remember seeing years ago my old Intel MacBook had noticeably higher cpu usage when connected to and using a Pluggable dock which had a Realtek Ethernet chipset. Switching to WiFi reduced cpu usage. AFAIK had something to do with bad and/or lack of hardware processing in the Realtek chipset so it had to do it on the cpu.
Now I never trust anything with Realtek in it, and if buying anything with an Ethernet port, I try to make sure it’s not Realtek. Is this still valid concern, or is Realtek better now?
I remember in the Intel days, the Apple Thunderbolt 1 GbE adapter would have high CPU usage when you were transferring at the full 1 Gbps.
I've had good luck with the Realtek 2.5 GbE adapters, no CPU usage issues.
And these days even with a 10 GbE Thunderbolt adapter the CPU use is negligible, so things have improved across the board I think.
