This is also a strong point of AVX2. It extends all integer SIMD operations to 256-bit, supports vector-vector shifts, various shuffle operations, and gather. This means practically every scalar operation gets a vector equivalent, making it straightforward to parallelize loops with independent iterations: http://software.intel.com/en-us/blogs/2011/06/13/haswell-new-instruction-descriptions-now-available/

So the CPU cores will be more powerful than the IGP at generic computing.
