RT-AX88U Pro vs GT-AX6000: Asus’ Solid Twins

Posted on

This RT-AX88U Pro vs GT-AX6000 matchup is to answer all the questions I’ve been getting since the review of the former.

Apparently, my lumping the original RT-AX88U in the review made things harder for folks to figure out which to get out of this particular pair.

Or maybe it’s just hard by default. I can’t say which is better. They are two distinctive Wi-Fi 6 routers with identical hardware on the inside.

But the bottom line is if you’re not hot on design and aesthetics (or the lack thereof,) pick the one that costs less.

Asus RT-AX88U Pro vs GT-AX6000: Different routers of the same specs and features

You’d have no issue telling the RT-AX88U Pro and GT-AX6000 apart. They look totally different.

The former has a traditional look of a typical Wi-Fi router, dating back to the beginning of Wi-Fi, whereas the latter tries hard to impress with a bold design and a flashy Aura game light.

And that’s about i. On the inside, the two are virtually the same. The table below will give you the details of how similar the two are, despite their distinctive looks.

Asus RT-AX88U Pro vs GT-AX6000: Performance and grading

The two routers are also very similar in performance, and consequently, they are both rated similarly.


Excellent Wi-Fi wired, and network storage performance

Tons of useful features, including AiMesh 2.0 and Pro-only Guest Network Pro and VLAN

Two 2.5GbE Multi-Gig ports with Dual-WAN and Link Aggregation support

Universal setting backup and restoration


Pro-enabled features are still in the Beta

Only 6 networks port (instead of 9 in the previous variant)

No Wi-Fi 6E, not wall-mount-ready

Asus RT-AX88U Pro vs GT-AX6000: The two share similar performances.
Asus RT-AX88U Pro vs GT-AX6000: The two share similar performances. That’s especially true, considering I tested them using two different major firmware releases.


Fast, reliable Wi-Fi with excellent coverage

Dual Multi-Gig ports with Dual-WAN, Link Aggregations, and more

Tons of helpful networking features and settings, including AiMesh 2.0 and gaming-related applications

Robust web UI, well-designed mobile app, no login account required

Multi-Gig, WAN/LAN Link Aggregation support

Excellent NAS performance when hosting a portable drive

Bold-looking design, no fan, runs cool


Lowest Multi-Gig grade (2.5Gbps), there could be more ports considering the router’s massive physical size

Impractical antenna design, bulky, not practically wall-mountable

The takeaway

As mentioned, it’s impossible to say which is “better” in this Asus RT-AX88U Pro vs GT-AX6000 matchup. The biggest thing that sets them apart is their appearance.

The good news is both are excellent Wi-Fi 6 routers. And you can upgrade either to Wi-Fi 6E via an access point.

So again, pick whichever fits your style, or cheaper if you can’t decide. Or get both and build a Multi-Gig mesh system with them.

For those who keep asking me what I’d pick, for the last time, I already have both — multiple units of each, in fact. But that has nothing to do with money or style. Wanna try it? Changing your name to “Dong” would be the first step in the right direction.
