Is there a source to confirm iPhone is equipped with HSM? One theory is the low-end devices want to reduce cost, and furthermore, Android devices are manufactured and sold by more than one company. But you can argue the weakest will eventually participate or die.

Well it was all over the news - the Secure Enclave uses a special chip with a unique encryption key hard burnt into it. It encrypts everything that is encrypted on the iPhone, and uses a different key for each app I believe.

There are more details on the HSM in the iOS security guide here. https://www.apple.com/business/docs/iOS_Security_Guide.pdf https://www.apple.com/business/docs/iOS_Security_Guide.pdf

  This is HSM on the iPhone itself, or on the cloud side?

    The phone itself. All of the encryption is done in hardware, not just for performance, but for resistance against physical attacks. The dedicated processor is nothing short of Fort-Knox-like if that paper is to be believed fully.

iOS always include hardware accelerated components for various tasks, for example voice, video encoding are super fast on iOS and super slow on high end androids. Androids traditionally doesn't have any hardware acceleration modules.
