Arris SB8200 has 2 Gigabit Ethernet ports. It also supports link aggregation. You can connect both Ethernet ports as a bundle to achieve upload or download speeds of 2 Gbps. However, there are not many ISPs that support link aggregation. Talk to your ISP to know whether they support bundling of LAN gigabit ports.

The Motorola MB8600 has 4 Ethernet ports. Three of these ports are concealed behind a plastic label. The actual download speed is 1 Gbps, but it can theoretically support up to 3.8 Gbps through link aggregation.

Features Comparison

Arris SB8200 Features

The Arris SB8200 is compatible with Charter, Comcast and Cox, 3 of the biggest internet providers in the United States. None of these internet providers send data through the latest DOCSIS 3.1 standard at present, but this device will definitely boost speeds in your existing DOCSIS 3.0 network until the new delivery standard is made available. When this happens, modems will be able to upload data at speeds of 2 Gbps and download at 10 Gbps. That’s 10 times faster than the existing DOCSIS 3.0 standard.

The SB8200’s two Gigabit Ethernet ports provide twice the connectivity of a DOCSIS 3.0 modem. The ports can be used to provide wired connectivity to a gaming console or computer and sending data to a wireless router at the same time. The modem’s upstream and downstream channels allow you to download large files, stream movies and browse the web faster than before.

The front panel features 4 LED status icons – Receive, Online, Power and Send. The device also comes with a 2-year manufacturer warranty.

Motorola MB8600 Features

The Motorola MB8600 has a durable elliptic-cylindrical plastic case. Its main body is coated with a grey matte finish, while the thicker bottom section and narrower top are coated with a glossy black finish. The device stays cool thanks to its lateral vent holes. The top, right and left sides of the modem are also covered with a lot of cut-outs to guarantee proper airflow.

The device measures 7.0″ x 7.2″ x 2.2″ and weighs 18.4 ounces, so it’s quite heavy. Since the Motorola MB8600 doesn’t have any wall-mounting capability, you can only place it on a flat surface or on a desk. It has a front glossy section that features 5 LED lights, which show the status of the Downstream, Power, Online, LAN and Upstream. If you turn the modem around, you will see plenty of buttons and ports. The Reset button can be found at the top and underneath it are the 4 Gigabit Ethernet ports, the ON/OFF button, the Power port and the COAXial RF connector.

The modem has 4 ports so that it can serve different purposes. One of these is to use several IP addresses. This option is available only for business owners. When speeds higher than 1Gbps do become available, you may need to use 2 or more ports combined to get higher throughput. The MB8600 supports LAG, but you have to wait for service providers to include 2Gbps+ data plans in their offers.

The Motorola MB8600 has 128 MB NAND storage memory and 512 MB RAM. It can accommodate up to 8 upstream bonded channels and 32 SCQAM downstream channels. The device is compatible with Grande Communications, Comcast Xfinity and Cox. The maximum theoretical speed that the MB8600 offers is 1Gbps. If you live in a place where this kind of data plan is offered, you will enjoy a regular speed of 950Mbps. The maximum theoretical speed of the modem can be 3.8 Gbps, but you have to wait until ISPs permit link aggregation on all ports, 3.8 Gigabit+ speeds become available and consumer-type routers become capable of receiving everything the modem sends.
