Xfinity and Google Fiber are top-shelf internet providers in the US. While Google is Fiber Optic, Comcast mostly offers cable internet. Both fiber and cable internet have their own dominance and flaws, which I’ll discuss in this detailed comparison.

Both providers differ in most aspects, be it internet plans, availability, down & up speeds, and associated costs. In this article, I’ll compare Xfinity and Google Fiber head-to-head, and help you choose the right ISP.

Key Differences Between Google Fiber and Xfinity

Choice of Plans: Xfinity offers a range of plans and bundles, including internet, TV, and phone services. In contrast, Google Fiber has 4 plans — 1 Gbps, 2 Gbps, 5 Gbps, and 8 Gbps.

Download & Upload Speed: Google Fiber uses fiber-optic technology, which allows for faster and more reliable speeds. Xfinity, on the other hand, uses a hybrid fiber-coaxial network, which may not be as fast as fiber-optic, especially in uploads.

Data Cap: Google Fiber doesn’t have a data cap, whereas some Xfinity plans may have it, which can result in additional fees if customers exceed their allotted bandwidth.

Availability: Google Fiber is available in limited cities. Xfinity, on the other hand, has a lot wider coverage with availability in most major cities and towns.

Contract Length: Google Fiber has no-contract options, meaning customers can cancel it at any time without any penalties. Comcast typically requires customers to sign a contract for a specific period, such as one or two years, which can result in early termination fees if you cancel Xfinity Internet.

Cost: Fiber internet is generally more expensive than cable internet, and there’s no exception to it when it comes to Xfinity vs Google Fiber. Also, prices can vary depending on the location and the plan selected.

Installation: Google Fiber provides professional installation by a technician, which is included in the subscription. In contrast, with Comcast, you can either opt for Xfinity self-install or Pro installation at an additional cost.

Customer Service: Google is known for better customer service while Xfinity has mixed reviews in this regard, with occasional delays.

From affordable basic plans to more advanced ones, Xfinity offers varying internet plans. However, compared to Google Fiber, Xfinity’s faster plans tend to be pricier.

Now you may ask, does Xfinity have fiber internet?

Well, yes but a single plan named Gigabit Pro which offers a maximum download speed of 6,000 Mbps. However, unlike Google Fiber, you need to pay installation charges, equipment fees, and other charges.

Google Fiber vs Xfinity: Detailed Comparison

Google Fiber uses fiber-optic technology for faster and more reliable internet, while Xfinity uses hybrid fiber-coaxial technology with wider coverage and more packages.

I used both service providers for over 3 months and have compiled all the crucial information about my experience. So let’s start without any further ado.

Note: I have also compared Google Fiber with Spectrum, a close rival of Xfinity.

Speeds and Latency

In real life speed test with Google Fiber 2 Gig plan, my ASUS GT-AX11000 clocked 1951 Mbps in download and over 1839 Mbps in upload. The speed test was performed at 25 feet distance from the internet setup.

Google Fiber 2 Gig Speed Test

These are excellent and close to the advertised speed. The latency was as low as 2 ms, which is great for gaming and data intensive activities.

As far as Xfinity internet speed is concerned, with the highest speed, 1200 Mbps plan, my MacBook Air M2, clocked 1038.91 Mbps in download and 35.17 Mbps in upload. The latency was also quite low at about 9 ms.

Xfinity 1200 Mbps Speed Test

Winner: If you prioritize higher speed and lower latency, Google Fiber is for you. If you seek affordability and multiple choices, Xfinity is better.

Performance & Reliability

Well, both offer great speeds, but who is more reliable? I did the speed test multiple times and while Google Fiber was delivering consistent speeds, Xfinity was showing different download and upload speeds every other time.

I tried playing some multiplayer games like Call of Duty, Apex Legends, and Valorant on both networks and both of them did a great job. There were no lags or latency issues from either of them.

I was able to stream 4K movies and shows on multiple screens, make video calls, and play games all together on both the ISPs without any issues.

Google Fiber is generally considered more reliable than Xfinity. Xfinity’s network is also reliable but may be more prone to outages in certain areas or during extreme weather conditions. Nonetheless, I did not face any issues with either of them.

Winner: Both the providers are good in this, however, if I had to pick one, I’d pick Google Fiber.

Availability / Coverage

Google Fiber is available in select cities across 18 states. However, within each state, the coverage is limited to specific cities, so not all residents within a state will have access to Google Fiber.

Pricing & Other Costs

Google Fiber vs Xfinity Prices

Google Fiber offers two main plans – the 1 Gbps plan and the 2 Gbps plan, with the former priced at $70 per month and the latter at $100 per month. They do not charge anything extra for the equipment.

Google also offers free installation as well and there are no hidden charges.

On the other hand, Xfinity offers a range of plans with varying prices depending on the speed and location. The fiber plans start at about $70 a month and goes up to $300 a month. Some of their plans come with one/two-year contracts.

They also charge equipment rental fees. In addition to the base price, Xfinity also charges a variety of fees, such as installation fees and early termination fees if the customer cancels their contract early.

Xfinity also frequently offers promotional deals and discounts for new customers, which can provide significant savings.

Winner: Google Fiber has a more transparent pricing. Additionally, Google Fiber offers unlimited data usage on all of its plans, whereas Xfinity may charge extra fees for exceeding data usage limits.

Installation & Setup

New Google Fiber customers can benefit from a free professional installation. You may be required to make a $10 deposit, but it can be used towards your future bill payments.

On the other hand, Xfinity offers professional installation for a fee of $89.99. But they also offer self-installation for free.

The professional installation includes a technician who will install and set up the equipment, test the connection, and ensure that everything is working correctly.

I feel that Google Fiber installation is better as it’s included in the subscription. I felt that the Google technician was a bit more friendly and helpful when I asked him to remove the old ISP cable.

Winner: Google Fiber offers better installation than Xfinity by Comcast.
