The 5 GHz downlink plot shows very similar performance for both ASUS routers. Both produce far higher throughput than the NETGEAR in the low attenuation value tests, but converge with the NETGEAR from 30 dB on.
5 GHz Downlink Throughput vs. Attenuation
The 5 GHz uplink plot again shows both the RT-AC1900P and RT-AC68U with higher throughput than the NETGEAR for most of the test range. The AC1900P has a slight throughput advantage over the AC68U. But I doubt you'd see much of a difference in real world tests.
5 GHz Uplink Throughput vs. Attenuation
So those of you wondering whether you were missing out on a huge leap in performance by not being able to get your hands on an RT-AC1900P can stop. You're not missing anything other than speedier storage performance if you connect a USB 3.0 drive and are willing to disable the Reducing USB 3.0 interference setting.
ASUS RT-AC1900P & RT-AC68U Ranker Summaries
Nonetheless, the slight differences in results add up to earning an SNB #1 Ranked award. The former #1 AC1900 ranked champ, NETGEAR's R7000 Nighthawk moves down to #2 and the RT-AC68U now ties for #3 with D-Link's no-frills DIR-879.
