TP-Link Deco X68 AX3600 vs Orbi AX4200 RBK752

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).

Tri-band

The main difference between deco x68 and deco x60 is the addition of one 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. When compared to Netgear Orbi, almost all Orbi series do not provide wired backhaul option because Orbi distinguishes between Orbi units, which unit is used for mesh routers and which Orbi unit is used for satellites, so the two cannot be exchanged like in all Deco series.

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.

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).

Wifi

These two mesh router models provide slightly different total bandwidth even though they use the same three band models. Orbi rbk752 with three bands uses dedicated backhaul @5ghz 2400mbps, but Orbi does not provide wired backhaul option like Deco does, so Deco x68 can use all three radio bands for connected devices with wired backhaul option.

With Orbi rbk752 the total bandwidth for connected devices is 1800Mbps (600Mbps + 1200Mbps) because the @5GHz 2400Mbps radio band is used for dedicated backhaul. And this is the same as the ax1800 mesh router system in general with wired backhaul.

Meanwhile, deco x68 when using wired backhaul provides a total bandwidth of 3600Mbps for all connected devices. And of course, deco x68 is more profitable with wired backhaul compared to Orbi rbk752 with dedicated backhaul @2400Mbps.

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.

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.
