ARRIS SURFboard SB8200 Review

Netgear CM1000 Vs. Arris SB8200

Design

Netgear introduced a new design that featured a modem that could start upright. This design helps save space, especially if you intend to place it on a desk.

In addition to the upright design, the CM1000 has a polyhedron-shaped outer casing.

Combine this with LED indicator lights on the front panel, and you have an elegant yet futuristic-looking modem.

It houses a powerful chipset that requires constant cooling; thus, Netgear opted to make ventilation holes on the outer casing.

These ventilation holes are the polyhedron-shaped holes that you see on the outer casing.

Unlike the CM1000, which has an elegant design, the Arris SB8200 features a box-like shape. There is nothing fancy about the design, but it works.

It has a lightweight build that’s supported by 4 rubber pads at the bottom.

The SB8200 stands upright like the CM1000 and has LED indicators on the front panel. It also has ventilation holes on the outer casing, which help keep it cool.

However, the processor is powerful; thus, you can expect it to heat up occasionally. 

Overall, the CM1000 has a more elegant design. Therefore, if you’re more into designs, the CM1000 would be your ideal.

However, it has only one ethernet port, compared to two on the Arris SB8200.

DOCSIS Certified

Both modems feature the DOCSIS 3.1 technology, which in theory allows them to support up to 1Gbps upload speed and double the download speeds.

This is an improvement from the DOCSIS 3.0 technology, which could reach up to 1Gbps download speed and 200 Mbps upload speed.

However, only one of these cable modems can hit such speeds. What the Arris SB8200 lacks in design features, it makes up for in speed. It can reach up to 2 Gbps download speed and 1 Gbps upload speed.

Compare these speeds with what the CM1000 has to offer. It can only support up to 1 Gbps download speed and 300Mbps upload speed.

Both devices have DOCSIS 3.1, but the CM1000 is yet to utilize the technology’s full capabilities.

Compatibility with ISPs

Compatibility is arguably one of the primary considerations when comparing the Netgear CM1000 vs. Arris SB8200.

You need to confirm whether the modems are compatible with the ISPs in your area.

For example, Netgear is compatible with most of the top ISPs. Expect to enjoy good speeds with ISPs such as Spectrum, Cox, Xfinity, Time Warner, etc.

Other providers are in the process of adding the Netgear CM1000 to the list of supported devices.

However, this list isn’t exhaustive; thus, you’ll need to call your local provider and ask if they support the modem.

Also, check their website just to be sure. It’s better to be sure that having a modem you can’t use.

Also, ask if they offer plans that exceed 1 Gbps so that you know if it will be beneficial when you buy.

You’re purchasing such a modem so that you can enjoy 1Gbps download speeds, the least you can do is check whether your provider offers such plans.

You won’t get 1 Gbps, but you can get numbers close to that, maybe 900-950 Mbps. Netgear is best paired with XFINITY from Comcast.

And the best part is that if you’re an XFINITY customer, you can self activate without calling customer service.

Arris SB8200 is also compatible with the top ISPs but as mentioned above, check with your local ISP.

Gigabit Ethernet Port

The Netgear CM1000 has one Gigabit Ethernet Port compared to two on the SB8200.

The two ports on the SB8200 are not to connect different devices; instead, they are used for Link Aggregation Setup. This allows users to enjoy speeds greater than 1 Gbps.

Router Compatibility

Generally, cable modems are compatible with any routers, but they are a few exceptions.

You can buy a combined modem and router unit as it has the functions of both devices combined in one unit. However, none of these devices have such features.

A combined device is suitable for a basic user, but if you’re into advanced networking, you’ll need a separate router and modem.

This is why you’ll want to get either the Arris SB8200 or the Netgear CM1000. You’ll also need a router for these cable modems. But is any router you pick compatible with the modem?

In theory, the router should be compatible unless the modems block certain routers or have conflicting configuration settings.

If you’re switching from a rented router to a purchased router, be sure to contact your ISP and check if the router you want is compatible.

It might seem like too much of a hassle, but it’s better to have a setup that you can’t use. Therefore do more research on router connectivity or ask your ISP.

Both Arris and Netgear are popular cable modem brands; thus, your ISP will know which routers work best with their respective modems.

This section has no winner, as you’ll have to verify with your ISP if the modems are compatible with the router you want to buy.

Channel Bonding

Channel bonding initially debuted with the DOCSIS 3.0 and is present in the newer DOCSIS 3.1. The idea was to enable modems to increase the amount of traffic they could support by utilizing multiple channels.

This feature proved useful during peak hours when Internet Service Providers would limit internet speeds. Fortunately, with channel bonding, users could enjoy full internet speeds by utilizing multiple channels.

If you’ve experienced slow internet speeds from your ISPs, it’s because the ISPs serve hundreds or thousands of customers.

They typically throttle down each channel to support traffic expected during peak hours.

Consumers using DOCSIS 2.0 modems suffer the most as they have a single downstream and upstream channel. They can’t exploit channel bonding features due to the limited number of channels.

Luckily, both the CM1000 and the SB8200 modems have DOCSIS 3.1, which can support higher upload and download speeds.

Both modems feature 32×8 channel bonding. This means it has up to 32 downstream channels versus 8 upstream channels.

Speed

At 1Gbps download and 300 Mbps upload speed, the Netgear CM1000 offers great speed. According to TechRepublic, the average internet speed in the U.S. is 50.2 Mbps.

Some cities enjoy more than 100Mbps, which is about a tenth of what the CM1000 can support.

Such speeds should be sufficient for the average consumer. If you have an internet plan that offers Gigabit speeds, the CM1000 would be a great choice.

You can expect to enjoy seamless 4K streaming and online gaming.

However, if you want an even better experience, the Arris SB8200 would be the ideal option. It supports up to double the download speeds of the Netgear CM1000.

Think about how much better your streams will be. If it’s online gaming, you can expect a smoother experience.

Both devices are good, but the Arris SB8200 edges the Netgear due to its insane speeds.

Hardware Size

Both modems are equipped with Broadcom BCM3390 chipsets, which is an upgrade from the Intel Puma 6 chipset found in their respective predecessors.

The Arris SB8200 has a Broadcom BCM3390 chipset, 128MB Spansion flash memory NAND, 3 GB of RAM, and 16 MB Macronix NAND flash memory.

As mentioned earlier, the CM1000 has the same chipset, 256 MB RAM, and 128MB flash memory.

According to what’s written on the box, the DOCSIS 3.1 on the SB8200 can support 5 Gbps download speeds. However, it also says that the Gigabit ports can support a combined 2 Gbps.

This means that although the DOCSIS 3.1 can support higher download speeds, the SB8200 doesn’t have the hardware to support such speeds.

It’s expected that future modems will have the capacity to support 2.5Gbps per port, thus reaching the elusive 5Gbps.

It’s clear that Arris SB8200 wins this category with better RAM and overall better hardware that can support higher upload and download speeds.

Is Arris or Netgear Better?

The Netgear CM1000 vs. Arris SB8200 debate has continued for years, and it’s no surprise as both modems offer great features.

Netgear was the first to introduce the DOCSIS 3.1 to its modems, and Arris joined later but perfected the technology.

The CM1000 vs. SB8200 debate will continue, but in most cases, the SB8200 emerges as the winner.

You see, Arris equipped the SB8200 with better features and hardware. One could argue that the CM1000 has an elegant design and decent features.

However, if you look at the pricing, features of the CM1000 and compare the two with the latest cable modems, you’ll see that the CM1000 is lagging.

Some may argue that getting the CM1000 is not worth it as its decent features don’t justify the high pricing.  Here you have to decide whether you want to continue renting or get your own modem.

Ideally, you should get your own cable modem, and it should be the Arris SB8200. In this Arris SB8200  Netgear CM1000 debate, the former has better features and internet speeds.

You get two Gigabit ports instead of one on the Netgear CM1000.

Both companies ditched the Intel Puma 6 after it proved messy and opted to switch to the Broadcom chipset.

There isn’t much to compare here since both modems are sporting the same chipset. In addition to the chipset, both modems can support 1 Gbps data plans, but the Arris has the edge.

Both devices have the DOCSIS, as mentioned earlier, which should be future-proof. Despite the similarities, the Arris SB8200 is the better choice.

It has a spectrum analyzer and two ethernet ports for link aggregation.

Is The Arris SB8200 a Router?

No, the Arris SB8200 is a cable modem. It’s not a combined modem and router unit. It’s a 32×8 cable modem with two 1 Gigabit Ethernet ports and compatible with major ISP.

It’s been available for over 3 years and can still compete with the latest models.

Since it’s older than newer models, you can expect to get a good discount on it. It retails at about $150, which is a good deal for a DOCSIS 3.1 considering it’s up there with the best cable modems.

Since it’s not a router, you’ll need a router to complete the setup. You can check which routers are compatible with the modem.

However, as mentioned earlier, most modems are compatible with any router, but you can ask your ISP just to be safe.

You can even use a Netgear router to connect to an Arris cable modem. That would require a Netgear Smart Wizard Installation CD and an ethernet cable.

Netgear CM1000 Vs. Arris SB8200 Review – Which To Choose?

There is no denying that Netgear CM1000 is a good cable modem, but it’s upload speeds don’t match up to its price. You’d expect a cable modem at that price would offer more than 3 times the upload speeds.

You can easily get such low speeds on low budget cable modems. So, is there a way to justify the cost?

You can argue that it’s elegant design and ventilation partly justify the cost. Also, you can say that it’s download speeds are decent for 4K streaming.

Other than the design features, the Arris SB8200 floors the CM1000 in almost all other areas. It offers up 2Gbps download speeds and 1 Gbps upload.

Compare those speeds to what’s available on the CM1000. They cost almost the same price, but the SB8200 seems to be the clear favorite. 

The Arris SB8200 also has 2 ethernet ports, while the CM1000 has only one port. If you’re wondering which of the two to choose, the answer is simple – the Arris SB8200.
