Agner Fog’s manual lists a latency/reciprocal-throughput of 15/10 for 64-bit divide on Ivy Lake & Tiger Lake, vs 3/1 for 64-bit multiply. So division is 5-10x s

Agner Fog’s manual lists a latency/reciprocal-throughput of 15/10 for 64-bit divide on Ivy Lake & Tiger Lake, vs 3/1 for 64-bit multiply. So division is 5-10x slower than multiplication. https://www.agner.org/optimize/#manuals https://www.agner.org/optimize/#manuals
