RTL8125BG or intel i226?

Hi everyone,

I'm about to build my own openwrt x86 router using an Asus ROG MAXIMUS VIII motherboard and an Intel i7-7700k processor. I'm looking for a 4-port NIC and I'm torn between the Realtek 8125BG and the Intel i226. Which one do you recommend?

I've read that the i226 has better compatibility, lower latency, but also has disconnection issues on pre-built motherboards. Realteks, on the other hand, are not as good for Linux or as efficient as Intel.
Do you know if the Intel issue has been resolved, or would you recommend the Realteks instead?

As for the purpose, I'll go for intel.

That being said, you are about to use a powerfull CPU/motherboard for a simple task. It's a waste, it will have a high power consumption. Unless it's a testing device, it's not appropriate.
There are tiny PCs with several NICs that are very usefull as routers. There are other threads showing examples of such tiny PCs (I remember Fujitsu and Dell references). One may give better references.

For example, I'm currently using an i3-5005U/4 NICs which is way enough for a router, even with a high bandwith VPN.

i226-V is on my PC and works great. Never had an issue wired to my old WRT32X or my current GL-MT6000, both running OpenWrt of course. Also note i226-V has lower power consumption than i225-V did.

it's for testing, I'm not an expert, but I want to build a router with OpenWRT and use Docker for AdBlock and a media server with Plex. I currently have these services on multiple devices in my network and want to consolidate everything into one.

I will try undervolting the i7 to see if I can match or reduce the power consumption of my current devices, and if it doesn't work, I will consider building one or buy a miniPC.

Hi.
For testing it's a good solution, I have done it numerous times myself.
Oh, so in fact the PC will have several virtual services. Can be tricky :wink:
On a ROG motherboard, I have no doubt that there are a lot of overclocking tweaks, so you can use them to underclock. Reduce speed, disable devices (such as sound, COM ...)
