Not all plans are available in all areas. Provider plan, availability, and speed tier data provided by BroadbandNow.com. Speedtest real-world data is only present where sample size has reached significance within a region. Additionally, averages may include aggregated tests across multiple Internet Types (Fiber, DSL, Cable, etc.).
At Speedtest, we take great pride in offering accurate and reliable data that corroborates our ISP recommendations. This data is amassed from numerous tests conducted by millions worldwide choosing to use Speedtest. This ensures our analysis of ISP performance is not only trustworthy but also up-to-date, allowing us to present an unbiased, comprehensive picture of ISP capabilities.
Key metrics such as download speed, upload speed, and latency are paramount in assessing an ISP's performance. Download speed dictates the rapidity of streaming or downloading content to your device, while upload speed reflects the speed at which data is sent from your device to the internet. Latency, a crucial factor in online gaming and video calls, impacts the responsiveness of your internet connection. Armed with a thorough understanding of these aspects, you're well-placed to make a choice that aligns with your unique internet usage demands.
The type of ISP technology significantly influences your online experience. Fiber optic technology typically affords the quickest speeds, desirable for high-usage online activities. Cable internet can offer satisfactory download speeds, although upload speeds may not always keep pace. DSL provides acceptable speeds for basic internet usage, whereas satellite internet, often a sole option in remote areas, generally has higher latency and reduced speeds.
How Much Speed Do I Need?
Download speeds of at least 100 Mbps and upload speeds of at least 10 Mbps are widely considered fast enough to handle nearly any online activity. A quick guide to what speeds you need for different online activities is below, and you can read our full guide to internet speeds and performance for more information. Keep in mind that the numbers below are the bare minimum for one device at a time. If you’re trying to use multiple devices on a network at the same time, you’ll want higher speeds.

ISP Speeds in Denver, CO
Denver, the mile-high city known for its beautiful mountainscapes and vibrant, diverse urban feel, now boasts the fastest recorded internet speeds in the United States thanks to the latest data from our Speedtest insights. Among the various internet service providers (ISPs) in the city, XFINITY stands out with the highest recorded median download speed of 276 Mbps. This impressive speed is indicative of XFINITY's robust service offerings and makes it a top choice for residents seeking fast and reliable internet connectivity.
When examining the advertised maximum download speeds, a few providers make notable claims. Quantum Fiber leads with an ambitious promise of up to 8,000 Mbps (or 8 Gbps) download speed, a speed that far surpasses typical household needs and is indicative of the potential of fiber internet. Similarly, XFINITY's offer of up to 2,000 Mbps (2 Gbps) and CenturyLink's 940 Mbps showcase the high-speed capabilities of cable and fiber internet, respectively. It's important for consumers to note, however, that there may be a discrepancy between advertised and actualized speeds.
A good rule of thumb to keep in mind is that download speeds of at least 100 Mbps and upload speeds of 10 Mbps are considered fast enough for nearly any online activity, including streaming 4K high-definition videos, downloading large files, or gaming on multiple devices. The actual speed requirement for a household heavily depends on the cumulative internet usage within the home, including the number of devices connected simultaneously. As the digital landscape evolves with more devices becoming integral to our daily lives, the need for faster and more reliable internet connections becomes increasingly important.

Home Internet in Denver
Denver, nestled at the base of the Rocky Mountains, not only offers picturesque views but also a diversified array of internet service options for its residents. Providers in the Mile High city offer a range of internet types, including DSL, fiber, satellite, 5G internet, and fixed wireless, ensuring that regardless of where you live or your internet needs, there's likely a service that fits into your lifestyle. Fiber internet, known for its high-speed and reliability, is prominently advertised by providers like Quantum Fiber, highlighting Denver's commitment to cutting-edge technology and high-quality service.
For residents prioritizing extensive coverage, XFINITY and CenturyLink rise above the rest, with XFINITY covering 95.05% of the city and CenturyLink's services available to over half of Denver's population. This high availability, especially for non-satellite and non-fixed wireless services, ensures that most Denverites can enjoy a reliable and high-quality internet connection. Such extensive coverage by cable and fiber internet providers guarantees that whether you're streaming your favorite shows, working from home, or engaging in online gaming, you'll have access to the speeds you need.
With an average starting price for internet services at $63.13, Denver's residents have a breadth of pricing options to fit various budgets. While some plans offer rates lower than this average, XFINITY provides the most budget-friendly option with a starting price of $30, albeit with lower speeds that scale up to its maximum advertised 2,000 Mbps offering at a much higher price point. It's crucial for consumers to remember that while higher prices often correlate with faster speeds, the actual performance can vary due to a myriad of factors. As such, comparing both price and performance is essential when choosing an ISP.
