Intel announces AVX2

The instruction set war is still there – Intel still doesn’t plan to support many XOP features of AMD; also Intel still plans to use FMA3 while AMD uses FMA4. Nevertheless, this time Intel is at least not making the war even worse. In addition to extending most SSE2/SSE3/SSE4 instructions to 256 bits (this is no surprise), they copied BMI (with an extension called BMI2) and CVT16 from AMD. If I recall correctly, Intel had never copied so many instructions from AMD at once, with the notable exception of x86-64.
