WebMay 24, 2024 · The contest between a dedicated instruction operating on 64 bits at a time (popcnt) and a series of vector instructions operating on 256 bits at a time (AVX2) turns out to be interesting. In fact, we show that we can achieve twice the speed of an optimized popcnt -based function using AVX2: 0.52 versus 1.02 cycles per 8 bytes on large arrays.
