the warp scheduler can dual-issue instructions; it has to because otherwise 192 fp32 alus can't be used by the 4 warp schedulers (4 x 32) effectively. increased ipc can do this for you. this was maxwell though; the ratio of resources to schedulers to sm has changed a lot in pascal. look up "dual-issue": http://on-demand.gputechconf.com/gtc/2013/presentations/S3466-Programming-Guidelines-GPU-Architecture.pdf http://on-demand.gputechconf.com/gtc/2013/presentations/S346...
