Does Zen 5 have cldemote or senduipi ?
- adrian_b 2y agoProbably not. The gcc Zen 5 patch adds as new instructions only AVX-VNNI, MOVDIRI, MOVDIR64B, AVX-512-VP2INTERSECT and PREFETCHI. Zen 4 already had AVX-512 VNNI (for ML/AI), AVX VNNI is only an alternate encoding for the programs that use only AVX (because they have been compiled for Intel Alder Lake/Raptor Lake). MOVDIRI and MOVDIR64B can be very useful in some device drivers, less often in general-purpose programs.
