Minimum Arithmetic

Select the smaller of two operands.

Vendor-Neutral Definition

d = (a < b) ? a : b, evaluated per the operand's type (integer or IEEE-754 float).
⚠️ Cross-vendor mappings describe semantic relationships and are not guaranteed one-to-one compiler translations.
equivalent with restrictions Both select the smaller of two operands; PTX's min is one family covering float/signed/unsigned via a type modifier, where AMDGPU exposes a differently-named instruction per type.

Version / Target Introduced PTX ISA 1.0 gfx1100, gfx1100, gfx1100

Important Differences

  • PTX's min is ONE family spanning f32/f64/s16/s32/s64/u16/u32/u64; AMDGPU requires selecting the correctly-typed instruction (v_min_f32 vs v_min_i32 vs v_min_u32, etc.) rather than one generic mnemonic.
  • NaN-handling for the floating-point form is hardware-generation-specific on both vendors and not verified to match bit-for-bit here.
