The Orbi RBK852 is definitely a better router, but is the right one for you? Let’s get into more details below. 


Both Orbi RBK752 and RBK852 are competent and top-of-the-line routers. But in terms of performance, which is best? 

We’ll be looking at:

  • Wifi speeds
  • Processors
  • Memory

WiFi Speeds

The Orbi RBK752 and Orbi RBK852 are both tri-band wifi mesh systems, which means they have one 2.4GHz channel and two 5GHz channels.  

Band #Orbi RBK752Orbi RBK852
12.4GHz band: 600 Mbps2.4GHz band: 1200 Mbps
25GHz bands: 1200 Mbps5GHz band: 2400 Mbps
35GHz band: 2400 Mbps5GHz band: 2400 Mbps

Looking at the table, Orbi RBK752 seems to offer slower speeds.  But it’s not really the case. With one of the 5GHz bands at 1200 Mbps, the RBK752 uses the higher 5GHz band to backhaul connection to the router.

In this sense, it’s not drastically slower. So it’s ideal for mid-sized homes or offices with fewer demanding users.

RBK852 is at a larger advantage because it offers double the speeds of RBK752. Aside from that, it doesn’t strain the internet speed of any of the users. Everybody can easily enjoy the fast speeds of WiFi 6 and stream 4k videos or play games without interference. 

Winner: Orbi RBK852

Processor and memory 

Your Orbi’s processor and memory play an essential role in speeding up your internet. 

Basically, the higher the processor and memory, the more your Orbi could “breathe.” Then it could handle more devices, storage, and firmware.

Processor:1.4 GHz Quad-core2.2GHz Quad-core
Memory Flash:512MB512MB

The table shows that Orbi RBK852 has a higher processor and memory. With the 1GB of RAM and 512MB of storage, it has a great capacity to store up firmware and settings.

Essentially, Orbi RBK752 is still a high-end router. But in this case, RBK852 is far superior to RBK752 and other models in general.

Features and Design

Choosing the design is often a no-brainer. But Orbi RBK752 and RBK852 both look modern and sleek. 

So let’s look at some differences that make each router unique. We’ll compare the physical design, port, security, and customization features. 

Design and Features

Design and FeaturesOrbi RBK752Orbi RBK852

Passive cooling system

The RBK752 has the signature oval tower look with a LED light at the bottom. It measures about 9.4 x 6.5 x 2.0 inches, which is much smaller than other Netgear models.  It fits most places that other models can’t, and it has soft rubber feet. 

The RBK852 also has the signature oval tower look and LED light. But it is bigger than RBK752, measuring up to 10.0 x 7.5 x 2.8 inches. 

Even though these models have plenty of differences in specifications, they have a lot of similarities design-wise. 

RBK752 and RBK852 have no built-in wall mounting bracket, but you could now get one! Both have an LED light band near the bottom that indicates the device’s status.

In addition, you won’t have to worry about your devices overheating. The RBK752 and RBK852 use a passive cooling system wherein air comes in from the bottom and goes out the top. This way, the devices never go beyond 35 degrees Celsius.

Ethernet Ports5 Total8 Total
MU-MIMO Technology

The RBK752 units have 6 high-performing antennas. This reflects the use of Qualcomm’s Networking Pro 800 Wi-Fi chip. It can support fast data streams, but not as much as the RBK852.

Through MU-MIMO and beamforming, the router can sort out signals so it can provide optimum speeds to all connected devices. The only downside is, it doesn’t support ultra-wide 160MHz data channels. 

Lastly, RBK752 has a 1 Gbps WAN port and 3 LAN ports.

As for the RBK852 units, they have 8 high-performing antennas. Powered by its Qualcomm Networking Pro 1200 chip, it can support 4X4 data streams.

With MU-MIMO and beamforming, it can sort out signals so it can provide lightning speeds to all connected devices. Theoretically, it can move up to 6gbps of data — back and forth. 

Lastly, RBK852 has a 2.5 Gbps WAN port and 4 LAN ports. 

Winner: Orbi RBK852


Orbi RBK752 costs around $400, while the Orbi RBK852 costs around $700. Of course, the cost for each device varies depending on what pack you want to get. 

When you purchase an Orbi, it normally comes in a 2-pack set: 1 router and 1 satellite. Of course, the price would get higher if you get additional satellites.
