Usually, 64-bit hardware runs a 64-bit OS. However, in the budget smartphone market (common with MediaTek or Snapdragon 400-series chipsets), manufacturers often implement a to reduce RAM usage.

This refers to the CPU architecture. Even if a processor is 64-bit capable, some older devices run a 32-bit operating system environment to save memory.
When Project Treble was introduced, it allowed users to flash a Generic System Image (GSI) to update their phones independently of the manufacturer. However, if your phone has a "64-bit Binder" but a "32-bit CPU architecture" software stack, a standard ARM32 GSI will crash immediately. The systemarm32binder64 image was created specifically to bridge this gap, allowing enthusiasts to run Android 11, 12, or 13 on aging budget hardware. How to Use a .img.xz GSI If you have downloaded a file with this
These are common in the arm32_binder64 ecosystem because the hardware is often poorly documented by the original manufacturer. Conclusion
The file is a lifesaver for owners of specific budget Android devices that would otherwise be stuck on outdated software. It represents the community's effort to ensure that no hardware is left behind, regardless of how strange the manufacturer's original partition and binder configuration might be. However, if your phone has a "64-bit Binder"
This indicates the image is for the /system partition of the device.
