Agner Fog has performance tables for many variants [1]. I’d guess a few pipeline to similar per loop cost of shift and add. I suppose if you’re writing a paper you’re aware of quite a bit of literature on exactly this problem. Recent papers have quite fast methods to do this. Agner Fog's "instruction_tables.pdf" is the most comprehensive single document for latency and throughput, with the added benefit of including AMD (and Via) processors and maintaining all the historical results in mostly the same presentation form.

The best place to find historical data on this is in Agner Fog's excellent "instruction tables" document, available at http://www.agner.org/optimize/instruction_tables.pdf As an example from that reference, looking at the MOVAPS and MOVUPS instructions for 128-bit loads from memory, the tables show that the penalty for using the MOVUPS instruction on aligned addresses disappeared Why do none of them – aside from ARM itself – publish tables of instruction latency and throughput? Plenty of people complain about Intel’s documentation, but the Software Optimization Guide coupled to all the supplementary information (Agner Fog, uops.info) is a wonderful source of information by comparison.
