* ARM NEON SIMD: around 2,000 instructions, prerequisite: ARM Scalar.
* ARM SVE: around 4,000 instructions, prerequisite: NEON and ARM Scalar
* ARM SVE2: around 1,000 instructions, prerequisite: SVE, NEON, and
- ARM Scalar
+ ARM Scalar for a grand total of well over 7,000 instructions.
* Intel AVX-512: around 4,000 instructions, prerequisite AVX, AVX2,
AVX-128 and AVX-256 which in turn critically rely on the rest of
x86, for a grand total of well over 10,000 instructions.
