Some of these measurements depend on the host as much as on the GPU: launch overhead is CPU dispatch cost, transfer rates are bounded by the host link and the host's memory system, and the CPU baselines run entirely on the host. Results for one GPU are reported separately per host architecture whenever it has been measured on more than one.
