Comcast is providing faster internet to your home, but be prepared to pay handsomely for it.

The company announced Wednesday that it will deliver speeds up to one gigabit-per-second to its residential customers in Houston.

The service will cost new customers $159.95 a month, without a contract, though Comcast is currently testing promotional pricing of $109.99 a month. Current Xfinity customers will pay an additional $50 to $70 a month to add 1 Gig service to their current bundle.

What can this download speed do? Comcast says it can be used to download a 600 megabytes show in four seconds, a five gigabytes movie in 40 seconds and a 15 gigabytes game in two minutes.

The upload speed of Comcast's new service is 35 megabits-per-second.

"We realize technological innovations are occurring rapidly, and our customers' need the speed to make the most of them," Ralph Martinez, senior vice president of Comcast's Houston region, said in the news release. "This increase reflects our commitment to delivering the fastest speeds to our customers, just like we've done almost every year for more than a decade."

The new service will use Comcast's existing infrastructure. To get faster speeds, customers need to install a new DOCSIS 3.1 compatible cable modem capable of delivering gigabit speeds.

The faster service is available Wednesday in west and northwest Houston including Spring, Katy, Rosenberg and Cypress. Comcast will continue rolling out this service in Houston during the next several months.

Comcast's current offerings range from 25 megabits-per-second to 250 megabits-per-second. It does offer two gigabits, but this requires a fiber-to-the-home solution as well as specific requirements for the computer's operating system, processor, memory, Ethernet connectivity and browser.
