How does AT&T compare to Xfinity internet?

In a comparison of top-rated internet service providers (ISPs), Xfinity and AT&T are two heavyweights. Comcast’s Xfinity cable internet has the largest subscriber base of any ISP in the U.S. AT&T has a smaller footprint, but it is the most extensive fiber-optic internet network in the country. Both are well-known and highly-rated ISPs, but which might be the best fit for you?

Who AT&T and Xfinity internet are for

AT&T fiber is an excellent choice for households where the highest speeds are required, such as those where several devices will be streaming video, online gaming, or engaging in video calls simultaneously. Also, AT&T offers DSL internet plans, but the speeds are much lower. DSL service is primarily available in rural areas and provides an option for those who can’t get cable or fiber internet service.

Xfinity is also an option for people who stream videos, play games online, or work at home. With Xfinity, you can get speeds up to 3000Mbps, though you’ll pay a premium price of $300/month for this speed.

However, Xfinity’s other plans are suited for those who may do a lot of downloading of data, such as video streaming, but who don’t send a lot of data. The reason? Outside of the premium 3000Mbps plan, which is the company’s only fiber offering, other Xfinity packages have upload speeds that fell well below the download speed. For example, the 1000Mbps download plan only offers up to 35Mbps upload speed. So if you do a lot of video conferencing or use a voice over IP (VoIP) phone system, these upload speeds may not be sufficient.

Comparison of internet services

Though the plan structuring is quite different, the two providers offer similar services. The difference in Comcast vs. AT&T internet comes down to a view of three different services: DSL (AT&T), cable (Xfinity), and fiber (both).

AT&T’s Fiber download speeds range from 300Mbps to 5000Mbps with a price of $55 to $180. Regardless of which plan you choose, the maximum upload speeds will always approximately match the download speed. These prices are consistent across all coverage zones, primarily the mid-west, south, and west coast, and none of the plans require an annual contract.

On the DSL side of AT&T’s internet offerings, download speeds range from 10Mbps to 100Mbps, depending on the location, for a price of $55 the first year.

Comcast breaks its plans into three regions: West, Central, and Northeast. There are slight differences in the plans offered among these three regions. Maximum download speeds in all three areas range from 100Mbps to 3000Mbps. In the West and Central division, the price range for these plans is $20 to $300/month. However, in the Northeast division, the 300Mbps plan starts at $49.99/month instead of $20. All of these plans are for cable internet, except for the 3000Mbps option, which is a fiber connection.*
