The Key Differences
The key differences between Netgear CM1000 and Arris SB8200
Similarities between Netgear CM1000 and Arris SB8200
- Both the modems are DOCSIS 3.1 compatible
- Both support DOCSIS 3.0 fallback
- Backward compatible
- Compatible with leading ISPs like Xfinity, Cox, Spectrum, and more
- Both the modems come equipped with the BCM3390 chipset
Design & Port Setup
Now that the more pressing matters i.e. differences and similarities are out of the way, it’s time to focus on expanding the discussion, as per the more obvious and essential parameters.
As far as the design is concerned, the CM1000 looks a tad grim with triangular vents for improved airflow and heat dissipation. The dimensions and heft are tagged at 8.8 x 5.4 x 5.9 inches and 0.84 pounds to be exact, making it easier to carry around.
The SB8200 is way more aesthetic but weighs a lot more at 2.2 pounds. As far as the dimensions are concerned, it measures 5.24 x 4.24 x 1.65 inches. Therefore, if you are fine with the additional weight, increased overheating, and 5 bright LEDs, the modem from Arris is a better bet.
Port setup is pretty straightforward with Arris trumping Netgear with an additional Ethernet slot for faster-wired connections.
Speed & Compatibility
If you would be interested in wireless speeds, there isn’t much to choose between the two modems, except the additional GigE port on the SB8200. Either way, it all depends on what the ISP chooses to offer in terms of bandwidth.
With a Gigabit+ internet plan to rely on, both these modems can very well return download speeds of up to 960Mbps, as tested. However, only if you are willing to invest in two internet packages, can you purchase the Arris SB8200, especially for its ability to reach 2Gbps, in terms of wired throughput.
ISP compatibility is hardly an issue here as both these modems pair up perfectly with Cox and Comcast Xfinity, provided you want to explore all the relevant traits of each. Restricted support for Time Warner, Brighthouse, and Charter is also available and depends on which internet plan you choose to invest in.
Who should buy the Netgear CM1000?
You can consider the Netgear CM1000 if you are looking for:
- Durable yet portable modem
- Faster wireless speeds when connected to the relevant routers
- Modem for large offices and home establishments
- The device that hardly heats up
- Improved modem stability
- Modem to manage Gig+ internet plans with precision
- Support for IP calling, video conferencing, and other tasks
Who should buy the Arris SB8200?
Investing in the Arris SB8200 makes sense if you want:
- Modem for streaming, 4K gaming, and other demanding tasks
- To set up wide-area networks by combining multiple internet plans
- Easy modem configuration
In the aforementioned sections, I compared and contrasted the Netgear CM1000 and Arris SB8200 across multiple parameters. I analyzed each of them for the speeds, ports, design, aesthetics, heating or the lack thereof, hardware setup, ISP compatibility, pricing, and several other traits.
However, I still feel that there isn’t much to choose between the modems except for a bit of additional processing power and an additional port on the SB8200. Both these modems are future-proof with DOCSIS 3.1 2×2 OFDM/OFDMA support but are also backward compatible with DOCSIS 3.0 setups. Therefore, the speeds expected are more or less uniform, if you are planning to compare them over an identical internet plan.
That said, if I were to choose and recommend only one, the Arris SB8200 is easily the better bet, courtesy of the massive RAM for cutting through congestion and the additional GigE port that has already been discussed at length.
