Looking for a great high speed cable modem? Well, the Arris Surfboard SB6141 and SB6190 are two of the best modems in the market. The following is a comprehensive review highlighting their major features and differences.

Arris has been in the modem making business for many decades now. They’ve provided us with some of the best cable modems and among them are the Surfboard SB6141 and SB6190. The former was released first and featured high bandwidth and overall great performance. The SB6190 on the other came way later and is a much more improved version of the SB6141. Being from the same manufacturer, there is little to separate these two when it comes to physical design. However, they differ in the following ways

Arris Surfboard SB6141 VS SB6190 – How do they compare?

Streaming capabilities

The best way to test the performance and speed of a cable modem is to look at it streaming capabilities. This is done by a series of tests that look at the behavior of the modems when streaming very high resolution videos and how long it takes to download large files. Here, the Surfboard SB6190 takes the win. The modem boasts speeds of up to 1400 Mbps for the download speed and 262 Mbps for the upload speed. This is more than enough to stream in 4K as well as download large gigabit files in just a few minutes. The SB6141 on the other hand does download speeds of up to 343 Mbps and 131 Mbps for uploads. It is a better choice for simple everyday use rather than high performance handling. If raw power and speed is what you want, the SB6190 should be your pick


It’s important that the modem you pick is attractive and practical in terms of space and placement in the house. Usually, larger modems are less practical since they consumes too much space or look out of place with your home décor. With these two modems, there is little to separate them since Arris uses similar designs for the Surfboard series. However, the SB6190 is smaller and therefore more practical for home use. Both are matte white or black in color and feature LED icon lights at the front. The matte ensures fingerprints do not stick on the surface. On both sides, the modems are beveled for breathability and cooling. The SB6141 features a Motorola logo that may be confusing for some. But this is simply because the company acquired the Mororola brand, Zoom, responsible for manufacturing modems. All in all, the SB6190 is stunning, smaller and goes well with any interior décor

Compatibility is cable internet providers

When looking for a modem, always select one that supports as many cable internet providers as possible. For our case, the SB6190 is such a choice. The modem supports all the major ISPs in the US from Charter, Cox and Comcast, among others. While this is also true for both, the SB6141 is not compatible with newer providers such as BrightHouse. This may present major issues for people under this provider. Therefore, always go for the safer choice – the Surfboard SB6190

Gigabit Ethernet Ports

Here, we have a tie with both modems coming with one Ethernet port each. Theoretically, the ports should provide up to 1 Gbps of data transfer speeds. However, this translates to about 130 Mbps on the SB6141 and 200 Mbps on the SB6190. The presence of one port also means performance boosting features such as link aggregation (LAG) are not supported.


Another top consideration when choosing between the SB6141 and SB6190 is the cost. The SB6141 excels in this category because of its affordability and value for money. While it provides lower speeds, the modem costs less than a hundred bucks. On top of this, it saves you money that is otherwise spent on renting out the IPS provided modem.
