Amazon’s Fire TV Cube and the Roku Ultra both offer an easy, inexpensive way to turn your standard television set into a smart TV. Because the devices are so similar, many people wonder what the differences between the two are.

Both Fire TV Cube and Roku Ultra can stream video in 4K HD, and both are compatible with Amazon Alexa. The biggest difference between the two devices is the price. There are many differences between them, but there are also a lot of similarities.

Below, we’ll discuss everything you need to know to decide between these two products. Keep reading to learn more!

The Fire TV Cube

The Fire TV Cube is manufactured and sold primarily by Amazon, but it’s also available at other major retailers. It costs $80, including a one-year limited warranty in case anything goes wrong. In the box, you’ll find:

  • The Fire TV Cube
  • A remote
  • A power cord
  • An ethernet adapter
  • An IR extender cable
  • Two AAA batteries for the remote

To use the Fire TV Cube, you will need to connect it to your television with an HDMI cable. This cable is not included in the box, so you’ll need to purchase one separately if you don’t already have it. If price is your biggest concern, this is definitely something to keep in mind.

This device is equipped with eight different microphones and offers Amazon Alexa capabilities. You can use it to find specific movies or shows, open an app, or even turn your television on or off. If you have other Alexa smart home products, you can even connect your Cube to them to do things like turn off the lights!

The remote also includes a microphone and Alexa Voice button. If you’re far away from the television or have a lot of background noise, you can also push this button to speak directly into the remote and access Alexa.


The Fire TV Cube streams video in 4K Ultra HD and includes 16GB of storage for any apps you want to download. From the Amazon Appstore, you can download streaming platforms including:

  • Hulu
  • Netflix
  • HBO Max
  • Disney Plus
  • Amazon Prime Video

In addition to the 16GB of storage on the device, purchasing a Fire TV Cube will give you unlimited Amazon Cloud storage.

The Roku Ultra

The Roku Ultra is available on the Roku website, Amazon, and at many other retailers. It costs around $100, and if you purchase it through Roku, you get a 30-day money-back guarantee. When you buy a new Roku Ultra, you get the following items:

  • The Roku Ultra player
  • A remote
  • Headphones
  • An HDMI cord
  • A power cord
  • Two AA batteries for your remote

When you activate your Roku Ultra, you’ll also get a free 30-day trial of HBO Max. The remote includes a voice button, which you can use to open an app or find a certain show. If you have an Apple Homekit, Amazon Alexa device, or Google Home device, you can connect your Roku Ultra to them to control other parts of your home with the remote.

All of the popular streaming platforms are available for download on the Roku store. The Roku Ultra is also compatible with Airplay, allowing you to mirror your phone to share photos, videos, music, or stream content via Bluetooth.

There are also a couple of convenience-based features included with the Roku Ultra. One of these is the “Remote Finder.” If you misplace your remote, you can press a button on your player, and the remote will play a sound until you find it. There is also a headphone jack on the remote, and you can plug in the included headphones to listen to your TV privately. Like the Fire TV Cube, the Roku Ultra streams video in 4K HDR when available.

Will a Fire TV Cube or Roku Ultra Work with Any Television?

The great thing about Amazon Fire and Roku devices is that they can turn nearly any television into a smart TV. As long as your television has a working HDMI port, it is compatible with either of these devices.

If you have an older TV without an HDMI port, there are still ways to make these devices work on your television. If you have RCA ports (the ones with a red, yellow, and white input), you can purchase an HDMI to RCA converter to use HDMI devices.

Final Thoughts

If you want a smart TV but don’t want to spend hundreds of dollars on a new television, a Fire TV Cube or a Roku Ultra are both excellent alternatives. The devices are very similar, but some people prefer one over the other. No matter which player you choose, these products provide an inexpensive way to stream nearly anything on any kind of television.
