Correct my possible misunderstanding but isn't this fabled "power" at best x4 performance gain and not really in the same league as GPU-esque?

Depending on your operations, e.g. With small buffers that fit in a cache line, transfers to GPU memory could cause GPU esque performance of less than 4x, even less than 1x whereas SIMD still provides benefits.
