WebbFor an AVX2 version with _mm256_i32gather_epi32, you'd have to use a different shuffle. Perhaps extract the high half, left shift it, word blend (vpblendw) so all the bytes you want are in one __m128i. Then vpshufb (_mm_shuffle_epi8) to put pack the 8 bytes you want down to the bottom of the register?
