Dual-band Wireless-AC1900 Gigabit Router
At a glanceWiFi5 Router Performance
December 2016
ProductASUS Dual-band Wireless-AC1900 Gigabit Router (RT-AC1900P)   [Website]
SummaryBest Buy exclusive version of popular AC1900 class router with Gigabit Ethernet ports and USB 2.0 / 3.0 storage and printer sharing.
Pros• Much faster USB 3.0 storage performance
Cons• More expensive than RT-AC68U

Typical Price: $200


ASUS' RT-AC68 is one of the company's best-selling wireless routers. Part of the reason is it's available in a dizzying array of versions. The table below, compiled by SNBForums member wouterv, attempts to summarize the differences.

ASUS also likes to create product versions exclusive to vendors and companies, notably the TM-AC1900 for T-Mobile (not shown above) and the RT-AC68P and RT-AC1900P SKUs exclusive to Best Buy. This is a great marketing strategy because exclusivity (and scarcity) tends to increase router geeks' product lust, even if the difference is nothing more than a model number.

In the RT-AC1900P's case, the only obvious difference in marketing literature is reference to its 1.4 GHz dual-core CPU vs. a 1 GHz dual-core CPU on the RT-AC68U. So does this change bring a significant performance difference? We'll see shortly.

I'm not to discuss any features in this review, as the ASUSwrt features are well-known. I'll be doing only component analysis and performance review.


The components used in the various RT-AC68 versions and now the RT-AC1900P are difficult to parse given all its FCC change filings. And the recent appearance of the RT-AC68UV2 in FCC filings hasn't helped either. This thread discusses the best information the SNBForums community has. So I opened up my test sample after testing for a look-see. Table 1 tells the tale.

Table 1: Component summary

I found these obvious differences between the original RT-AC68U (hardware V1) and the RT-AC1900P, which is labeled H/W version V3:

  • CPU change from a Broadcom BCM4708A to BCM4709C0
  • Increase in flash from 128 MB to 256 MB
  • 5 GHz power amp change from Skyworks SE5023L to SE5003L1
  • Shield over the USB connectors
  • Removal of the back panel ASUS logo backlight LEDs

I can't confirm the clock increase from 1 to 1.4 GHz because the clock device is marked "T250 P qF U", which doesn't equal either number or a multiple. As near as I can tell from the RT-AC68U photo below, its clock device is marked "2.5". Note also the same ESMT memory is used with the only change being -BDB from -ADB on the original.

Finally, it's important to note that the radio SoCs remain the same (BCM4360KMLG); the BCM43602 with onboard processor is not used.

Here's the RT-AC1900P board with heatsinks and RF can tops removed.
