[SOLVED] Ethernet Ports

[QuestionMaker21]

What's the difference between Intel I225-V and RJ45? Looking at some Z790 motherboards and some say RJ45, some say Intel I225-V

I225-V is the network controller (nic), rj45 is the cable connector size (cat 5e, 6).

Ah I see

All motherboards use rj45 plug. I225-V is 2.5gbe speed, other common speeds is gigabit. Gigabit or 100MB/s, can be utilised with cat 5e or 6 cable. 2.5gbe requires a router and cat 6 for those speeds + appropriate internet connection and storage drives to handle transfer rates. Also negotiation speeds between gigabit hardware and 2.5gbe can sometimes be problematic. If your house uses normal gigabit lan environment, don't get a motherboard with I225-V. Someone can correct me of course but it's what I've experienced with a friend over for a lan session and they had to rely on wifi because god forbid they couldn't connect via lan cable.

What is there other than I225-V? I have Gigabit internet

Im probably over reacting, the troubled I225-V was on a Asus Prime 590-a. Probably negotiation has been fixed on later gens. Couldn't say for sure.

A lot of boards have Intel ethernet, even AMD motherboards. Realtek offers many ethernet chipsets and are pretty common to see on motherboards. Marvell maybe sometimes, haven't seen one in a while.

Most other ethernet chips are found outside of the motherboard as discrete cards, components, routers, etc. Broadcom, TI, and Microchip and the like.
