Xfinity vs. Verizon: Performance
Quick Hit: Verizon Fios offers symmetrical speeds for intense uploading, while Xfinity delivers reliability and high-speed downloads backed by fiber-powered network infrastructure that can easily handle most households’ needs.
As two of the most popular internet providers in the country, Xfinity and Verizon have helped millions of customers access high-speed internet to power their everyday lives.
The main differentiator between Xfinity and Verizon comes down to the type of technology that delivers internet to homes, which can directly affect performance. Verizon Fios uses a dedicated, 100 percent fiber optic network that runs directly into residences. Xfinity operates on a hybrid fiber-coaxial network, which combines fiber technology with existing cable infrastructure, relying in part on the coaxial wiring that delivers cable TV into people’s homes.
While Xfinity also offers 100 percent fiber internet, it is currently available in select areas, and the other options from Verizon (like 5G Home Internet) are typically only worth considering if both Xfinity internet and Verizon Fios are unavailable in your area.
Speed
Taking the top spot for download speed and consistent quality among popular ISPs in the latest findings from Opensignal,1 Xfinity is built for speed, delivering ultra-fast connections powered by an advanced fiber-optic network that provides the low latency and high bandwidth required to support multiple devices simultaneously. Their fiber-backed infrastructure ensures seamless streaming, gaming and working from home without interruptions.
While their download speeds are often evenly matched, with Xfinity outperforming Verizon in some areas, fiber-to-the-home setup still has the edge for upload speeds. That’s because fiber internet, like Verizon Fios, offers upload speeds that match download speeds, while with cable internet, the upload speeds typically get up to 45 Mbps. While this may not affect the average person’s experience, people who stream 4K often, upload large files for work or livestream could benefit from the symmetrical speeds that fiber can deliver.
However, fiber-to-the-home connections come at a premium cost, and most households don’t require the full upload speed that fiber can provide. Instead, most people are most concerned with WiFi performance inside the home. With that in mind, Xfinity delivers sub-20 ms latency (or as gamers call it—ping) for optimized gaming and streaming performance.
Reliability
Verizon Fios’ all-fiber network is less prone to outages, interference or congestion, helping to solidify its reputation for reliability. But according to Opensignal, Xfinity WiFi was rated the most reliable between the two by real users.2 Xfinity delivers worry-free WiFi by utilizing advanced Gateway technology that optimizes network traffic, helping eliminate dead spots and reducing buffering during high-bandwidth activities. Xfinity’s network is powered by fiber-backed infrastructure, providing the low latency (the delay between action and reaction) and high bandwidth required to support multiple devices simultaneously. While both networks are considered dependable, performance during peak hours may vary by location.
Data
While they used to impose data caps, Xfinity has joined other leading ISPs in offering true unlimited data across all of their home internet plans, providing the freedom and flexibility to browse, stream, game and work without worrying about overage charges or a compromised connection. This plan perk is especially helpful for larger, multi-device households or heavy users who may consume more data on a daily basis. Verizon also offers unlimited data on their Fios plans, but customers may be subject to throttling on their 5G plans.
