That article linked to a Google post on Reddit: https://www.reddit.com/user/google/comments/16zrrbf/comment/k4m6szv/The article I read (linked below) seems to indicate that the Android 14 bit-perfect support requires OEM support as well. It's not completely clear, but it seems that OEM support would hint that it is somewhat hardware dependent. I'll be interested to see how it all pans out in the near future.

I don't think it is hardware dependent. He is saying that when an OEM builds an Android 14 release for their device, they need to update the Hardware Abstraction Layer portion of the Android software to match the device.
