Does Xfinity Offer Multi-Gig Speeds Using the 10G Platform?

Just a few years ago, multi-gig cable internet speeds seemed like science fiction. Now, you can get up to 2Gbps speeds with Xfinity, depending on where you live. Sure, Xfinity isn’t the only provider using the 10G platform to boost speeds, reliability, and security, but it definitely has the largest footprint of any cable internet provider in the U.S.

So, what exactly is the 10G platform? And does this mean you can now get 10Gbps cable internet speeds with Xfinity? Well, not quite yet, but that’s one of the long-term goals of the 10G platform.

We’ll explain more about what the 10G platform is, and when you should expect to see multi-gig speeds from the upgrade.

What is the 10G platform?

The 10G platform isn’t a specific internet plan or provider. It’s a development initiative spearheaded by CableLabs aimed at improving and boosting cable internet speeds to eventually reach 10Gbps. Xfinity uses a hybrid fiber/cable network to deliver internet, so upgrading the existing infrastructure is cheaper than replacing the cable internet portion with fiber.

Xfinity currently offers one of the fastest cable internet speeds in the nation, up to 2,000Mbps (2Gbps) down and 250Mbps up, using the 10G platform and the XB8 gateway (which supports 2.5Gbps downloads and Wi-Fi 6E).

But to take full advantage of fiber-like multi-gig symmetrical speeds, Xfinity is now introducing the XB10 gateway based on the newer DOCSIS 4.0 and Wi-Fi 7 specifications. Cable internet plans supporting multi-gig symmetrical speeds are dubbed as X-Class.

But multi-gig speeds aren’t the only goal Xfinity and the 10G platform strive for. With a goal that includes lower latency, symmetrical upload and download speeds, and improved reliability, the 10G platform is aiming to match every leg up fiber has on cable internet.

Finally, the 10G platform isn’t related to the 5G cellular network, just cable internet and certain cable internet providers.

How do Xfinity customers benefit from the 10G platform?

In 2023, Xfinity announced its upgraded network plans and long-term goals, which aligned with the overall objectives of the 10G platform. We’re already seeing the fruits of some of these goals from Xfinity: lower latency, faster speeds, and a more secure and reliable network with recently enhanced upload speeds and equipment upgrades. Xfinity has made sure that all the improvements, excluding symmetrical speeds, spread across its entire footprint across the U.S.

New and existing Xfinity customers should be experiencing an overall improvement in their internet service without having to sign up for a new plan. Customers will continue to see improvements in their connections as Xfinity rolls out more substantial upgrades and the groundwork for superfast symmetrical internet speeds.

Does Xfinity offer symmetrical fiber-like speeds?

Xfinity currently offers symmetrical speeds to customers in select areas. These plans are dubbed as X-Class (no relation to the X-Men) to distinguish them from the asymmetrical ones. You can get anywhere from 300Mbps all the way up to 2,000Mbps symmetrical download and upload speeds—if you have the XB10 gateway and live in an area where X-Class plans are available.

What’s the tech behind the upgraded Xfinity network?

The upgraded Xfinity network is the result of key infrastructure and equipment upgrades that have the potential to make ultra-fast and symmetrical speeds over a cable internet connection a reality. Distributed Access Architecture (DAA), DOCSIS 4.0, and Wi-Fi 7 each play a big part in Xfinity’s plans to deliver multi-gigabit symmetrical speeds to customers.

Xfinity WiFi Gateway, xFi, and Wi-Fi 7

Xfinity’s newest and most powerful gateway yet, the Xfinity WiFi Gateway (XB10), enhances the convenience of the upgraded Xfinity network by allowing customers to experience Xfinity’s speeds over Wi-Fi. You can add xFi Complete to your internet plan and maximize your Xfinity WiFi Gateway with added Wi-Fi controls and xFi Advanced Security for added cybersecurity protection.

The xFi features use Wi-Fi 7, which is capable of much faster speeds than the previous Wi-Fi 6. Wi-Fi 7 adds the new 6 GHz connection, providing more Wi-Fi space for compatible devices and far less latency to tighten up the responsiveness of things like gaming and video calls. It also handles interference better than previous specifications based on our tests, improving the speeds for devices that don’t support Wi-Fi 7.

Superfast symmetrical speeds with DOCSIS 4.0

One of the key goals of Xfinity’s upgrades is to prepare its entire cable network structure to utilize DOCSIS 4.0. Short for Data Over Cable Service Interface Specification, DOCSIS is an international standard used to deliver internet data over existing coax cable TV lines. DOCSIS 4.0 is the latest version and is essential for multi-gigabit symmetrical speeds.

Most cable internet service providers still use DOCSIS 3.1 modems and gateways, which are limited to 5Gbps down and 1.5Gbps up by design, while DOCSIS 4.0 supports up to 10Gbps down and 6Gbps up. DOCSIS 4.0 comes with better latency and security improvements, too.

Xfinity is still rolling out DOCSIS 4.0, so if you’re lucky enough to live in an area where Xfinity offers symmetrical speeds, you’ll reap the benefits of the latest DOCSIS from Xfinity.

So, when will I see 10Gbps speeds from Xfinity?

From what we can tell, Xfinity already offers a 10Gbps fiber internet plan called Gigabit x10. It’s not made available on its website. Instead, you must call Xfinity and request the service.

Xfinity began rolling out its XB10 gateway in mid-2025, which supports DOCSIS 4.0 and Wi-Fi 7. We’re already seeing 2Gbps cable internet speeds and Xfinity is continuing to roll out DOCSIS 4.0 and improve its network overall, but there is no guarantee or date on when 10Gbps will be available for Xfinity customers nationwide.

Cable internet is more widely available compared to fiber, so getting multi-gig speeds from providers like Xfinity that have a massive market is a significant achievement for the 10G platform. If you want to learn more, check out our guide on the 10G platform.
