Design and Build

Arris has a similar design, just like the previous three generations. It has a white color plastic case that has a matte finish. In terms of design, the SB8200 is nothing new and astonishing. 

Similar rounded edges that are creating a wrap around the rectangular Centerpiece. When looking at the structure of Arris SB8200, you cannot point out anything different from the previous models. On the other hand, Netgear CM1000 also has a pretty similar design from its processes, but it also comes with a few improvements that makes it different from the Arris SB8200.

Netgear CM1000 has a polyhedron-shaped case that is matte black giving a chic look to the entire modem. The edges of the modem are rounded. 

Arris SB8200 has soft lighting because of which Netgear CM1000 takes the lead because of its elegant look.

The comparison of both devices in this category ultimately depends on the taste of the user. Both of the devices have a pretty design although the Arris SB8200 might have few drawbacks. 

In a modem, overheating is quite common, which is addressed by this model of Netgear. It has provided triangular cuts that offer good heat dissipation as the airflow remains balanced, and the modem remains cool all the time.

Arris has also taken a few measures to address the overheating issue and has provided a proper ventilation system with cutouts in SB8200. We do not see any significant difference in terms of the design in both the devices; however, they majorly differ in size. 

The SB8200 is compact, and it measures 5.24 x 5.24 x 1.65 inches. The weight of this modem is 2.1 lbs. 

On the other hand, the CM1000 is taller in size with an 8.8 X 5.4 X 5.9 inches measurement. Even though being taller in size, this modem is lighter than the SB8200. 

The design comparison of both the products has done pretty well. Both Arris SB8200 and Netgear CM1000 have outstanding heat management and are provided with all the essential buttons, indicators, and ports. However, Arris SB8200 is supplied with a second Ethernet port that enhances the speed of the internet. 

So, with SB8200, you have an added advantage because of the additional Ethernet port.

Not many cable modems are compatible with Comcast cocks and charter; therefore, you get a massive advantage with both the modems. 

Both SB8200 and CM1000 have long durability, and they can stick to more than a year and a half without causing any connection problem. After a few years, you might see the slower updates but other than that, both the cable modem is pretty amazing. 

Since both the devices have DOCSIS 3.1 Technology, you should have a gigabit + data plan, which might not be affordable right now, but the companies are planning to make it so in the upcoming years. 

You get an average speed of 960 Mbps for both devices, which is good enough compared to the other instruments.

Both Arris SB8200 and Netgear CM1000 are up to the mark in the category of performance and compatibility, and you will get great speed on both modems. It would be best if you kept in mind that neither of the two devices has Wi-Fi capabilities built-in. If you wish to connect Wi-Fi devices, you will have to use an additional wireless modem.

Arris SB8200 is integrated with a Broadcom BCM3390 chipset that has a flash memory of 128 MB / 16 MB. In SB8200, you also get 3GB of RAM. 

The best thing is that Netgear is also equipped with a similar Broadcom chipset and flash memory. The only difference that you find is in the RAM, which is 256 MB in CM1000. 

There is a significant improvement in the hardware of both the companies because both the brands have stepped out of their comfort zone and have used a Broadcom-based chipset. 

Both the modems equipped their models with Intel Puma chipset because they have limited latency issues in their old models.

The incorporation of Broadcom-based chipset and DOCSIS 3.1 Technology lets you anticipate that you will get great internet and down-loading speed. However, it is written in the specifications that both the devices provide you with 5GBPS, which is not valid with SB8200. On Arris SB8200, you get 2GBPS in total. 

Netgear also shows the specification that the users will get 5 GBPS; however, the device can only work up to 1 GBPS, and the reason is the limitation of the ports. 

In the comparison of the hardware, Arris SB8200 takes the lead in terms of the speed output.

Other than that, both the devices are similar, and the integration of the Broadcom chip makes them strong against latency problems.

DOCSIS 3.1 Technology

As an alternative to the Fiber Technology, DOCSIS 3.1 was developed, which gives users 10gbps for downstream and 1gbps for upstream. With the arrival of this technology, users got highly excited and believed that it would provide them with good speed internet. 

Both of these cable modems can provide a smooth Gigabit performance to the users. So, let’s have a brief comparison of Arris SB8200 Vs. Netgear CM1000.
