My understanding is that the 850 is essentially identical to the 730. Is this true? Any advantages?

Hi Stephen, not exactly. R730 was built before Wi-Fi Alliance adopted Wi-Fi 6 certification. So, even though this AP is compliant with a subset of 802.11ax, it's never going to be Wi-Fi 6 certified (as opposed to R850).

A specific difference I'm aware of is uplink+downlink OFDMA support in R850 versus downlink only in R730

FCC has a Declaration of Similarity document. The R850 and R730 are basically identical EXCEPT the R850 has the Hawkeye v2 chipset (IPQ8078v2) which supports UL+DL-OFDMA and is Wifi 6 certifiable.

The R730 has the original v1 Hawkeye which definitely does not support UL-OFDMA. Whether or not it properly supports DL-OFDMA is still up in the air, with some vendors supporting it and others not (Ruckus as of the latest SmartZone release does not support OFDMA in either direction on R730)

Would there be a real world difference in performance?

Does the R850 support 160mhz ?

Not right now but that's a different issue. The two revisions of the chip don't work differently in terms of 160MHz. The general limitation with the chip being used is that 80+80/160MHz mode is basically reconfiguring the 8x8:8 5GHz radios to a 2 4x4:4 config. 

Long story short, neither the R730 nor the R850's current firmwares have 160MHz or 80+80 support.... But that's on par with the rest of the market that uses Hawkeye.
