Google Cardboard vs Google Daydream

Availability of Target Device

Google Cardboard has substantially more compatible devices, and due to its lower minimum required Android version, the devices it is compatible with are significantly cheaper, and thus easier to obtain. On the other hand, Google Daydream currently only runs on premium flagship devices, which can be much more difficult to obtain.

Minimum Development System Requirements

The development machine requirements for both Google Cardboard and Google Daydream are the same, as listed in the previous section.

Minimum Target System Requirements

The minimum target system requirements for Google Daydream are significantly higher than those for Google Cardboard, as Daydream applications are more intensive and thus require more power. Currently, only high-end devices are capable of running them.

Additionally, Google Daydream is only available on Android devices, as opposed to Google Cardboard, which supports both Android and iOS.

Power

GoogleVR supports all features of both Google Cardboard and Google Daydream.

Ease of Use

Google Cardboard is significantly easier to develop for than Google Daydream. All development for Google Cardboard can be done on the development machine without the need for an actual target device to test on.

On the other hand, Google Daydream has many more components involved in development. It does not strictly require a target device to test, as it is technically possible to use the mouse to emulate the controller pointing. However, any advanced movement with the controller does require a target device to be connected to the development machine, with the controller state being propagated through the target device to the development machine.

GoogleVR for both Google Cardboard and Google Daydream supports Instant Preview, which allows the user to test applications on target devices without the need to recompile the application every time by simply streaming the output to the device instead.
