How It Compares

vs. CM2500

Advantages

✓Slightly lower maximum download (2.0 Gbps) but still supports 1 Gbps upload.

Disadvantages

✗Maximum download speed is 0.5 Gbps lower than the CM3000.

Choose CM2500 if you need a slightly cheaper option and don’t require the top 2.5 Gbps download.

vs. CM2050V

Advantages

✓Supports 2.5 Gbps download speed similar to CM3000.

Disadvantages

✗Upload speed capped at 500 Mbps and may include voice support, making it slower for upstream tasks.

Select CM2050V if voice service is needed and 500 Mbps upload is sufficient.

vs. CM1200

Advantages

✓Provides 2.0 Gbps download with a single gigabit Ethernet port.

Disadvantages

✗Upload limited to 500 Mbps and lacks link aggregation, offering less upstream bandwidth.

CM1200 is suitable for users with modest upload needs and a single‑device setup.

vs. CM1000

Advantages

✓Entry‑level DOCSIS 3.1 modem at a lower cost.

Disadvantages

✗Only 500 Mbps upload and unspecified download speed, making it unsuitable for multi‑gig plans.

Best for budget‑conscious users who only need basic gigabit internet without high upload demands.
