Yes — 1000 Mbps is the same as 1 Gbps, because one gigabit equals exactly 1,000 megabits per second.
For the full breakdown, see our best 1000 Mbps Router guide.
That gap is the number most people call to complain about, and it’s the one worth understanding before you pay for an upgrade.
Providers count speed in decimal units, where 1 gigabit = 1,000 megabits. The standard question of whether a 1000 Mbps connection and a gigabit connection are the same thing has a short answer, and the fine print is where the confusion usually lives.
The Unit Math Behind 1000 Mbps
Internet speed prefixes are decimal in ISP advertising: 1 Gbps = 1000 Mbps, so the two terms name the identical speed. Xfinity states that one gigabit equals 1,000 Mbps and describes gigabit internet as 1 Gbps or faster.
Megabit and megabyte are not the same unit. Mbps measures connection throughput; MB/s measures how much data moves to disk.
Why Some “Gigabit” Plans Show 940 Mbps
Providers also split gigabit into two flavors. Symmetrical plans match upload and download; asymmetrical cable plans rarely do, and Xfinity’s own explainer frames “gigabit” as a 1 Gbps-or-faster tier rather than a locked single number.
- 1000 Mbps / 1 Gbps: the headline number in marketing.
What You Need To Actually Hit Gigabit Speeds
| Plan Label | Actual Speed | Typical Monthly Cost |
|---|---|---|
| 100 Mbps cable | ~100 Mbps | $40–$60 |
| Gigabit (940 Mbps) | ~940 Mbps | $60–$80 |
| Gigabit (1000 Mbps) | ~940–1000 Mbps | $60–$80 |
| 2 Gig fiber | ~2000 Mbps | $100–$120 |
| Multi-Gig (2.5G/5G) | ~2500–5000 Mbps | $110–$150 |
Who Actually Needs Gigabit Internet
Gigabit makes sense for households streaming 4K on multiple screens while gaming and uploading large files at the same time. A single user checking email and watching Netflix rarely feels the difference between 300 Mbps and 1000 Mbps.
For one or two people with light usage, the money is better spent on a solid router than a faster pipe.
Common Mistakes With Gigabit Plans
Three errors show up constantly. First, confusing Mbps with MB/s and thinking a 1000 Mbps plan should download at 1000 MB/s. Second, assuming every “1 Gig” plan delivers a flat 1000 Mbps to every device. Third, assuming “gigabit” always means exactly 1000 on the nose — a 940 Mbps plan can carry the gigabit label.
FAQs
Is 1 Gbps faster than 1000 Mbps?
No — they are identical. One gigabit equals exactly 1,000 megabits per second, so a 1 Gbps connection and a 1000 Mbps connection describe the same throughput. The difference is only in how the label is written, not in the speed you receive.
Why does my gigabit speed test show 940 Mbps?
A 940 Mbps result on a gigabit plan is normal and expected.
Do I need a special router for gigabit internet?
Yes — a gigabit-capable router with gigabit Ethernet ports is required to push near-1 Gbps speeds. Older routers with 100 Mbps ports cap the connection at that ceiling regardless of the plan you pay for, and Wi-Fi adds its own limits on top.
