Gbps vs Mbps Comparison: How It Impacts Your Broadband Speed

When shopping for broadband plans or comparing internet speeds, you've likely come across the terms "Gbps" and "Mbps." While both are used to measure internet speed, they represent different magnitudes of data transfer rates. Understanding the difference between Gbps and Mbps is crucial for making informed decisions about your broadband needs and ensuring you have the right plan for your household or business.

In this article, we'll explore the meaning of Gbps and Mbps, how they differ, and how they impact your internet experience. We'll also discuss factors to consider when choosing a broadband plan based on speed and provide a comparison of common internet activities and their speed requirements.

What is Mbps?

Mbps stands for "megabits per second" and is the most common unit used to measure internet speed. It represents the number of bits (binary digits) that can be transferred per second, with one megabit equal to 1,000,000 bits. Mbps is used to measure both download and upload speeds, which are crucial factors in determining the overall performance of your internet connection.

Download speed refers to the rate at which data is transferred from the Internet to your device, while upload speed refers to the rate at which data is transferred from your device to the Internet. Download speed is typically more important for most users, as it affects activities like browsing the web, streaming video, and downloading files. Upload speed, on the other hand, is crucial for tasks like video conferencing, online gaming, and sharing large files.

What is Gbps?

Gbps stands for "gigabits per second" and is a larger unit of measurement for internet speed. One gigabit is equal to 1,000 megabits, meaning that 1 Gbps is equivalent to 1,000 Mbps. Gbps is used to measure ultra-fast internet speeds that are becoming increasingly available with the expansion of fibre-optic networks and advanced broadband technologies.

To put this in perspective, a 1 Gbps connection can transfer 1 gigabit (or 1,000 megabits) of data per second, which is roughly 100 times faster than a typical 10 Mbps connection. With a 1 Gbps connection, you could download a full HD movie in just a few seconds, compared to several minutes with a 10 Mbps connection.

The Impact of Mbps and Gbps on Your Internet Experience

The difference between Mbps and Gbps can have a significant impact on your internet experience, particularly when it comes to high-bandwidth activities like streaming, gaming, and downloading large files. The table below provides a comparison of common internet activities and their recommended speed requirements:

Activity Recommended Speed (Mbps)
Email and web browsing 1-5 Mbps
Social media 3-10 Mbps
HD video streaming 5-10 Mbps
4K video streaming 25+ Mbps
Online gaming 3-6 Mbps
Video conferencing 3-10 Mbps
Large file downloads 10+ Mbps
Multiple devices/users 25+ Mbps

As you can see, the speed requirements for different activities vary considerably. While basic tasks like email and web browsing can be accomplished with speeds as low as 1-5 Mbps, more demanding activities like 4K video streaming and large file downloads require significantly higher speeds.

When choosing a broadband plan, it's essential to consider not only your individual needs but also the number of devices and users in your household. A family of four with multiple devices streaming, gaming, and browsing simultaneously will require a much higher speed than a single user primarily using the internet for email and social media.

The Availability of Mbps and Gbps Speeds

The availability of Mbps and Gbps speeds varies depending on your location, service provider, and the type of broadband technology used. In the UK, the most common types of broadband are:

  1. ADSL (Asymmetric Digital Subscriber Line): ADSL uses existing telephone lines to deliver internet speeds typically ranging from 10-24 Mbps.
  2. Cable: Cable broadband uses coaxial cables to deliver internet speeds typically ranging from 30-500 Mbps, with some providers offering speeds up to 1 Gbps.
  3. Fibre-optic: Fibre-optic broadband uses fibre-optic cables to deliver ultra-fast internet speeds, with many providers offering plans ranging from 100 Mbps to 1 Gbps or higher.

According to Ofcom's 2021 Connected Nations report, 96% of UK homes and businesses have access to broadband speeds of at least 30 Mbps (superfast broadband), while 60% have access to speeds of at least 300 Mbps (ultrafast broadband). Gigabit-capable broadband (with speeds of at least 1 Gbps) is now available to 47% of UK homes and businesses, with the government aiming to extend this coverage to 85% by 2025.

Factors Affecting Your Actual Internet Speed

It's important to note that the advertised speed of your broadband plan may not always match the actual speed you experience. Several factors can impact your internet speed, including:

  1. Network congestion: During peak usage hours, when many people are online simultaneously, your internet speed may slow down due to network congestion.
  2. Distance from the exchange: For ADSL and some fibre-optic connections, the farther you are from the provider's exchange, the slower your internet speed may be.
  3. Hardware limitations: Older modems, routers, or devices may not be capable of supporting the maximum speed of your broadband plan.
  4. Wi-Fi interference: If you're using Wi-Fi, obstacles like walls, floors, and electrical appliances can interfere with the signal and reduce your internet speed.
  5. Wired vs. wireless connections: Wired Ethernet connections generally provide faster and more stable speeds compared to Wi-Fi.

To ensure you're getting the best possible speed from your broadband plan, it's recommended to use a wired Ethernet connection when possible, keep your modem and router updated, and position your Wi-Fi router in a central location away from interference sources.

Real-World Speed Comparisons

To put Mbps and Gbps speeds into perspective, let's look at some real-world examples of how long it would take to download a 5 GB file (roughly the size of a full HD movie) with different connection speeds:

Connection Speed Download Time
10 Mbps 1 hour 8 min
50 Mbps 13 min 39 sec
100 Mbps 6 min 49 sec
500 Mbps 1 min 22 sec
1 Gbps 40 sec

As you can see, the difference between Mbps and Gbps speeds can be substantial. While a 10 Mbps connection would take over an hour to download a 5 GB file, a 1 Gbps connection could accomplish the same task in just 40 seconds.

  1. Your household's speed requirements: Determine the number of users and devices in your household and the types of online activities they engage in. Use the recommended speed table provided earlier as a guideline.
  2. The availability of broadband technologies in your area: Check which types of broadband (ADSL, cable, fibre-optic) are available at your address and compare the speeds and prices offered by different providers.
  3. Your budget: Gigabit-speed plans are typically more expensive than slower plans. Decide how much you're willing to spend on your broadband service and look for the best value within your budget.
  4. Contract length and terms: Pay attention to the contract length, early termination fees, and any additional costs (e.g., installation, equipment rental) when comparing broadband plans.
  5. Upload speed: If you frequently engage in activities that require high upload speeds, such as video conferencing or cloud storage, consider plans with higher upload speeds or symmetrical speeds (equal download and upload).

Testing Your Internet Speed

To determine your current internet speed and ensure you're getting the speed you're paying for, you can use online speed testing tools like or These tools measure your download and upload speeds and provide information on your ping (latency) and jitter (variability in latency).

When running a speed test, make sure to:

  1. Close any unnecessary programs and apps that may be using your internet connection.
  2. Connect your device directly to your modem or router with an Ethernet cable, if possible.
  3. Perform multiple tests at different times of the day to account for variations in network congestion.

If you consistently experience speeds lower than what you're paying for, contact your internet service provider to troubleshoot the issue. They may need to investigate your connection, equipment, or network infrastructure to identify and resolve any problems.

Bits (b)

A bit (binary digit) is the smallest unit of data in computing. It represents a single value that can be either 0 or 1. Bits are used to encode and transmit data across networks, such as the internet. Internet speeds, like Mbps and Gbps, are measured in bits per second.


  • A 100 Mbps internet connection transfers 100 megabits (100,000,000 bits) per second.

Bytes (B)

A byte is a unit of digital information consisting of 8 bits. Bytes are used to measure file sizes and storage capacity. One byte can represent a single character, such as a letter, number, or symbol.


  • A 5 MB (megabyte) image file consists of 5,000,000 bytes (40,000,000 bits).

Conversion between Bits and Bytes

To convert between bits and bytes, use the following formulas:

  • Bits to Bytes: divide the number of bits by 8
  • Bytes to Bits: multiply the number of bytes by 8


  • 100 Mbps (megabits per second) = 12.5 MB/s (megabytes per second)
  • 5 MB (megabytes) = 40 Mb (megabits)

Prefixes: Kilo, Mega, Giga, Tera

When discussing bits and bytes, you'll often encounter prefixes like kilo (K), mega (M), giga (G), and tera (T). These prefixes indicate the scale of the unit.

  • Kilo: 1,000 (10^3)
  • Mega: 1,000,000 (10^6)
  • Giga: 1,000,000,000 (10^9)
  • Tera: 1,000,000,000,000 (10^12)


  • 1 Gbps (gigabit per second) = 1,000 Mbps (megabits per second)
  • 1 TB (terabyte) = 1,000 GB (gigabytes)

Understanding the difference between bits and bytes is important when comparing internet speeds, file sizes, and storage capacities. Remember that internet speeds are usually measured in bits per second (bps), while file sizes and storage are typically measured in bytes (B).
