"ARMHF stands for "ARM hard float", and is the name given to a Debian port for ARM processors (armv7+) that have hardware floating point support, which is found on most modern 32-bit ARM boards. ARM64 (also known as AArch64) is the 64-bit extension of the ARM architecture. Raspberry Pi unveiled the beta of its 64-bit version of its Debian-based OS alongside its then new 8GB Raspberry Pi 4 in mid-2020, and is now gradually becoming more commonplace.

In short, ARMHF is 32-bit, and ARM64 is 64-bit."
