How much of a performance increase would this result in? It highly depends on the application. Some could run two times faster or even more (if they didn't use SIMD instructions before). Some will see practically no benefit from AVX2. But keep in mind that Intel focusses on improving performance fo...

AVX2 is both evolution and revolution. It's an evolution in the sense that it's just another x86 instruction set extension. It's the successor of SSE1, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, and AVX1. It is revolutionary for the addition of 'gather' support and other instructions which make it feasible ...
