TP-Link Deco X68 AX3600 vs Orbi AX4200 RBK752 Which One is Better

TP Link introduces another series of Deco mesh wifi-6 system – the Deco x68 mesh wifi-6 system in addition of Deco x60 which has been around in the market for a while. How good is Deco x68 compared with Netgear Orbi Rbk750?

Deco x68

If you have been familiar with the tp link deco x60, then with the deco x68 released by tp link you will think that this product is not much different from the previous deco x60. However, this TP link deco x68 has similar technology (AI driven mesh) with the deco x90 series which was released earlier to the market couple of months ago, although there are major differences between the two deco series.

Deco x68 vs deco x60

It’s good to see what changes made from the deco x60 series and then the deco x68 that was released to the market soon after the deco x90 was. With the improvement of deco x60 to deco x68, of course, it will provide better competitiveness if you have to compete with Orbi rbk752. Initially deco x60 had to compete with rbk752 which is certainly superior to deco x60. See also deco x60 ax3000 vs orbi rbk752 ax4200.

Now, take a look at the following spec comparison table between Deco x68 and deco x60 (table 1).

The main difference between deco x68 and deco x60 is the addition of another 5GHz radio band that is used as dedicated backhaul to link between deco nodes. With deco x60 that comes with dual band the backhaul link between the nodes is shared bandwidth @5GHz radio band. 

Both deco x60 and deco x68 provide a wired backhaul option that uses wired Ethernet connection between nodes using an Cat5e or Cat6 UTP cable connection which is much more reliable than wifi backhaul which is prone to signal interference.

Since both deco x68 and x60 come only with two Ethernet ports, with wired Ethernet backhaul you can only configure them in daisy chain topology. Or you can add an unmanaged Ethernet switch to configure all the three deco units connect to the switch with star topology.

When compared to Netgear Orbi, almost all Orbi series come with dedicated backhaul and optional wired Ethernet backhaul. With Orbi that comes with four Ethernet ports like Orbi rbk750 series, you can connect the other Orbi satellites to the router Orbi unit in star topology.

Faster processor

With three band technology, the process is certainly heavier than a dual band router; it is therefore deco x68 uses quad core processor with faster clock rate than the deco x60 does. The same quad core processor is also embedded by Netgear Orbi Rbk750 with slightly lower clock rate than x68.

Deco x68 vs deco x90

Deco x68 is between deco x60 and the newest model deco x90. Considering that the price difference between x68 and x90 is quite a lot, you need to be wise which one is suitable to meet your home need. Have a look at the following table 2 that shows you spec difference between the two products. Later we can see which one is comparable to Orbi rbk752.

Different network segment

Both series are tri-band mesh wifi, but different in which network segment each series works on. Deco x90 works @ax6600 is delivering around 40% more aggregated bandwidth than deco x68. In addition, should require multi Gig Ethernet port up to 2.4Gbps for high speed Internet plan up to 2Gbps, deco x90 should be your choice, and off course you need cable modem with 2.4Gbps port too.

TP Link Deco x68 vs Orbi Rbk752

Can this new series of deco x68 compete with Orbi rbk752 better than deco x60? Let’s see the spec comparison between the deco x68 and the Orbi rbk752 (two units of the rbk750 series, one Orbi router and one Orbi satellite).

Orbi Rbk752 AX4200
Orbi Rbk752 AX4200


These two mesh router models provide slightly total bandwidth different even though they use the same three band models. Orbi rbk752 with three bands uses dedicated backhaul @5ghz, and deco x68 uses dedicated backhaul @1,800Mbps. Both models offer optional wired backhaul.

With Orbi rbk752 the total bandwidth for connected devices is 1800Mbps (600Mbps + 1200Mbps) because the @5GHz 2400Mbps radio band is used for dedicated backhaul. With deco x68 you also have the same aggregated bandwidth for connected devices (1,200 + 600), and the 1,800Mbps @5GHz radio band is used as dedicated backhaul.

Orbi rbk752 provides wider bandwidth for dedicated backhaul than Deco x68. Orbi with two satellites requires wider bandwidth in rush hours.

Ethernet Ports

Whether with mesh wifi you still need more wired Ethernet connections such as game consoles, internet TV or desktop PCs, the Orbi provides more Ethernet ports (3+2) than the deco x68 which only provides 3 ports.

When you connect the other two Orbi satellites using wired backhaul instead of wifi backhaul, you can connect them to the router unit in star topology, you can connect directly to the router which has 3x LAN ports. So you don’t need separate Ethernet switch.

On the other hand should like to configure all deco units with wired Ethernet backhaul, you can do that by connecting all deco units with daisy chain topology. Or you require an unmanaged switch to connect them in star topology.

With a more economical price than Orbi rbk752, this deco x68 is more promising with a total bandwidth of 3600Mbps with wired Ethernet backhaul option. If running Ethernet cable for connection between nodes is not a problem then the cheaper deco x68 compared to Orbi rbk752 is a reasonable choice.
