My guess, and it’s only a guess, is that AMD may only license the chips if they’re used with their in-house wifi designs. You can always swap out the wifi later if needed.

AMDs move to partner with Mediatek for a Wi-Fi module is likely strategic due to Intel taking more steps to move the wireless chipset portion from a separate module to their SoC. Intel started their CNVi push around ~2017 and it has only expanded more and more over the years.

There are essentially 2 types of Intel WiFi modules:-

• AX201 Integrates with and requires hardware functionality present only within Intel CPU’s

• AX200 Has everything on-board and works in all systems.

I haven’t checked, so someone might correct me, but I would be surprised if the WiFi modules {manufacturer} have been providing aren’t the AX201.

I would still possibly buy and install my own Intel AX200 WiFi6 / WiFi6E module, because Intel wireless has proven to be reliable, perform extremely well, inexpensive and has excellent driver support.

I have no idea how the AMDRZ616 stacks up. MediaTek were AMD’s dev partner for this WiFi module and it could be that it’s a really excellent piece of hardware despite that MediaTek are, in my mind, associated with low-performing, not great Android targeted SoC’s and similarly “not quite as good as other OEMs” TV I/O / SoC stuff.

For the price, it’s not exactly the worst idea to just try both options. Installing WiFi modules can be fiddly, but not impossible for most people.
