Mbps vs. Gbps: Do You Need Gigabit Internet?

A gigabit is one thousand times bigger than a megabit, which means gigabit internet (1,000 Mbps or faster) is one thousand times faster than megabit internet. Most major internet providers now offer gigabit plans, but they’re overkill if you don’t need blazing fast speeds.

Most people have a general idea of how internet speed is measured, but it can be hard to grasp just how big the differences between these speeds are. Not to worry. We’re here to break down the technical details as simple as possible so you can determine if you need gigabit internet speeds or a slower connection.

Do I need gigabit internet speeds?

Your need for gigabit internet speeds depends on what you do online. There are many good reasons why you should get the fastest internet available, like reducing download times and improving the quality of video streams. And gigabit internet is simply the best connection for online activities that require lots of bandwidth.

Of course, not everything we do online requires a fast connection, so you won’t notice a huge improvement when checking your email, for instance.

Here are some online activities where you won’t notice much of a difference and some where you will.

Less bandwidthMore bandwidth
  • Surfing the web
  • Checking email
  • Playing games online
  • Streaming music
  • Watching videos
  • Downloading large files
  • Video chatting
  • Livestreaming
  • Downloading games
  • Streaming games
  • Streaming video

    Streaming video is one of the most bandwidth-intensive things you can do online. If you have people streaming on multiple devices in your home, the speed requirements can add up fast. 

    To help, video services like Netflix and Hulu have a lot of tricks for keeping your viewing experience smooth, such as preloading (buffering) video in the background and lowering the video quality if your connection can’t handle the load. But even Netflix can’t help much if too many people try to stream at the same time.

    Gigabit internet is so fast that you could have a dozen people streaming in 4K at the same time and still be using less than half of your available bandwidth.

    Video chat

    Video chat needs a fast connection, just like streaming video. The big difference is that while Netflix needs a fast download speed, video chat needs both its upload and download speeds to be fast. This is where the type of connection becomes more important. 

    A gigabit cable connection probably has enough upload speed for a stable video call, but a gigabit fiber connection runs at gigabit speeds both ways. This makes it ideal for video chat like Zoom and Skype, as well as livestreaming on sites like Twitch

    Gaming online

    Gaming online doesn’t require a lot of bandwidth. Speed is still important for having your game play smoothly, but it’s latency, rather than bandwidth, that is most important. The higher your latency, the more lag you will experience when playing. Most gigabit connections (especially fiber) have really low latency—but you can often get the low-latency connection you need for online games without splurging on the fastest plan available.

    Streaming games

    Game streaming is different from online gaming. Services like Stadia and PlayStation Now stream games to your devices from the cloud similar to how movies and TV shows are streamed from Netflix and Hulu. However, because games require constant interaction, you need good download and upload speeds for smooth gameplay.

    Stadia, for instance, requires a constant download speed of at least 35 Mbps to play in a 4K resolution. That can be problematic on a 100 Mbps plan when everyone else in the house is streaming other content.

    Which providers offer gigabit internet?

    Most internet providers offer a gigabit plan. Many plans cap at 940 Mbps because internet providers use a small portion (overhead) of your gigabit bandwidth to help deliver a fast connection. All plans are subject to network congestion and forces of nature, so your actual speeds will fluctuate.

    What separates fiber gigabit plans from cable gigabit plans is that fiber typically has identical upload and download speeds. With cable, your upload speed is just a small fraction of your download speed.

    Mbps vs. Gbps: What’s the difference?

    The difference between Mbps and Gbps is the number of bits you can send and receive each second.

    In the days of dial-up, modems were usually measured in kilobits per second (Kbps), like 28.8k and 56k. Modern-day broadband speeds are now measured in megabits per second (Mbps) or in gigabits per second (Gbps). Here’s how the bits stack up:

    • 1,000 bits = 1 kilobit
    • 1,000 kilobits = 1 megabit (or 1 million bits)
    • 1,000 megabits = 1 gigabit (or 1 billion bits)

    We think of internet speed in terms of time. If your internet connection were a faucet and your provider cranked down on the knob, the water (data) merely trickles in a thin stream (1 Mbps) and slowly fills the sink. If your provider turns up the knob, data flows like a waterfall (1,000 Mbps). It’s the same faucet, only the sink fills up faster when more data flows out.

    Bits vs. Bytes: What’s the difference?

    Although internet speed is generally measured in bits per second, you might also see terms like “megabytes” and “gigabytes.” Bits and bytes are both units of data, but they’re used in different circumstances.

    • 1 bit = This is a single unit of data that is either a “1” or a “0”
    • 1 byte = 8 bits

    The term “bit” is typically associated with hardware and software. For instance, a 64-bit processor can handle a single data unit containing 64 bits. The term “byte” is typically associated with file size and storage because 100 GB is easier to remember and shorter to write than 800,000 Mb.

    The bottom line is that internet speed is measured in megabits (Mb) or gigabits (Gb) whereas storage and file size is measured in megabytes (MB) and gigabytes (GB). Note the use of the lower-case “b” for speed and the upper-case “B” for size.

    How to convert between Mbps and Gbps

    Because data rates are metric, converting between data rates is pretty easy. To move from one metric prefix to the next, you just multiply or divide by 1,000. In other words, you just have to add or remove three zeros at the end of the number (or shift the decimal point by three places).

    For example, to find how fast a 1,200 Mbps internet connection is in kbps, you would multiply by 1,000:

    1,200 × 1,000 = 1,200,000 kbps

    To convert this same speed to gigabits per second, you would divide by 1,000:

    1,200 ÷ 1,000 = 1.2 Gbps

    You don’t normally have to convert between bits and bytes (unless you’re trying to manually estimate how long a download would take), but to do so, just multiply the number of bytes by eight, or divide the number of bytes by eight.

    1,200 Mb = 150 MB

    FAQ about gigabit internet

    Do internet speeds go faster than a gigabit?

    The fastest speeds available for residential internet are multigigabit fiber connections, which currently top out at around 2 Gbps. Of course, if you look at the infrastructure that the internet is built on, you can find connections carrying much more data.

    For example, the undersea cables that connect continents measure their bandwidth in terabits per second (Tbps). That’s 1,000 faster than a gigabit per second.

    How do I get gigabit Wi-Fi?

    Since no single online activity comes close to requiring a gigabit connection on its own, most people interested in gigabit internet have a lot of devices to connect. The most convenient way to connect them all is over Wi-Fi unless your application demands a wired connection.

    Keep in mind that your wireless connection is only as fast as the slowest link in the chain. For example, your speed depends on two factors: your router and your device. If your router can’t handle wireless gigabit speeds, it will turn into a bottleneck for all wireless devices that support gigabit connections. If your wireless device can’t handle gigabit speeds, it will bottleneck your internet connection. Upgrading to one of the best Wi-Fi 6 routers you can buy won’t magically boost your wireless speed if your tablet supports only a 433 Mbps connection.

    If you need to upgrade your router, check out our review of the fastest routers for gigabit internet. However, a good rule of thumb is to make sure that your devices can support wireless gigabit speeds before you buy a gigabit wireless router. Check the device specifications on the manufacturer’s website.

    The verdict: Gigabit internet isn’t for everyone

    You don’t need a gigabit connection if all you do is surf the internet, check your email, and stream low-quality music. Gigabit plans aren’t exactly cheap, so there’s no need for the added expense if you’ll never utilize the boost in speed.

    Consider your online activities before taking the gigabit plunge. Livestreaming and lossless audio streaming require a wider data pipeline than watching cat videos on YouTube. Knowing the difference between megabits and gigabits is a great tool for gauging what you need against all the hype surrounding gigabit connectivity—now that you know, you can pay for gigabit internet only if you truly need it.
