But anyway.
Best theoretical max of the wifi 6 spec with the best protocol and frequency is 1200 Mbit/s, which is 150 MB/s. I highly doubt you can get anywhere near half that in real life but whatever.
m-pcie has a single lane of PCIe 1.0 (usually, it could theoretically have any PCIe revision but for some reason I always see them locked at the 1.0), which provides up to 250 MB/s up and 250 MB/s down at the same time, and it's a pretty efficient bus with low overhead so you are getting close to that in practice.
M.2 key A/E has 2 lanes of PCIe 2.0 (or better), which is something like complete fucking overkill, 1GB/s up and down at the same time.
1200x2=2400.
Just like the 9260 supports up to ~1733Mbt/s, via 2 streams.
866x2≈1733.
Edit: I just saw that the ~1200Mbt/s is only available via utilization of 160Mhz channels, the same as with the ~1733Mbt/s
20Mhz: 135-143.4Mbts
40Mhz: 271-286.8Mbts
80Mhz: 567-600.5Mbts
170Mhz 1134-1201Mbts
I merged the specs of the guard intervals, the full table can be found on Wikipedia.Last edited by moriel5; 07 April 2019, 03:51 AM.

Close enough I guess.

This is another Intel card using CNVi (look at the "system interface type" line) https://ark.intel.com/content/www/us...s-ac-9560.html

I think the latter is most likely as they can control the obsolescence of the system or of the cards (they can make a newer system that is no more compatible with CNVi 1.0 but only with CNVi 2.0 cards).

Whereas the 9560 shows M.2: CNVio.
I have been tracking Intel wireless cards since the 9260 was only rumored, to say the truth (though I had also been researching older cards, ever since the 8265 was released). .

Do you know if CNVi is going to be an option (i.e. they will make 2 versions of the card, like they do now with the 9560 vs 9260) or they will eventually make only CNVi cards?
I think the latter is most likely as they can control the obsolescence of the system or of the cards (they can make a newer system that is no more compatible with CNVi 1.0 but only with CNVi 2.0 cards).
