Arm Assembly vs x86 Assembly
Write AArch64 assembly when reverse-engineering iOS/Android binaries, bringing up bare-metal firmware on Cortex-M/A silicon, or hand-tuning NEON/SVE kernels where the compiler leaves performance on the table — nothing else gives register-level control on the chip running nearly every phone on Earth meets developers should learn x86 assembly when working on performance-critical applications, operating system kernels, or device drivers where fine-grained hardware control is essential. Here's our take.
Arm Assembly
Write AArch64 assembly when reverse-engineering iOS/Android binaries, bringing up bare-metal firmware on Cortex-M/A silicon, or hand-tuning NEON/SVE kernels where the compiler leaves performance on the table — nothing else gives register-level control on the chip running nearly every phone on Earth

Pros
- +Skip it for general embedded application logic: C plus intrinsics gets 95% of the speedup at a tenth of the debugging pain, so reach for that instead
- +Related to: gcc, gdb
Cons
- -Specific tradeoffs depend on your use case
x86 Assembly
Developers should learn x86 Assembly when working on performance-critical applications, operating system kernels, or device drivers where fine-grained hardware control is essential
Pros
- +It is also valuable for security professionals in malware analysis and exploit development, as understanding assembly helps in reverse engineering binary code and identifying vulnerabilities
- +Related to: reverse-engineering, operating-systems
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Arm Assembly if: You want skip it for general embedded application logic: c plus intrinsics gets 95% of the speedup at a tenth of the debugging pain, so reach for that instead and can live with specific tradeoffs depend on your use case.
Use x86 Assembly if: You prioritize it is also valuable for security professionals in malware analysis and exploit development, as understanding assembly helps in reverse engineering binary code and identifying vulnerabilities over what Arm Assembly offers.
