Difference between WCN7850 and WCN7851 ?

Difference between WCN7850 and WCN7851 ?

[GreyXor]

Hi, I'm interested in acquiring a WiFi 7 card for my laptop, and I came across the Qualcomm QCNCM865, which is Qualcomm's WiFi 7 card. Upon checking Wi-Cat, I noticed that it features a WCN7851 chipset. However, when examining the ath12k/linux source, I couldn't find any mention of the WCN7851; only the WCN7850 was referenced. What implications does this have? Can I still obtain a WCN7851, or would it be advisable to opt for a card with a WCN7850 chipset, given its greater number of updates and references in the kernel? Thank you for your assistance.

I don't know what changes WCN7851 has compared to WCN7850 but in general
these changes are transparently handled by the firmware and the host
driver just sees it as WCN7850. But I hope someone who is familiar with
WCN7851 can confirm this.

Another thing I want to point out: usually board files are a major
problem so before buying anything I recommend checking that there's a
board file available for ath12k.
