Opencl work group and G76 core

Hi,

I would like to ask whether a work group with 192 work items can run on multiple G76 cores?

I thought similar as other GPUs, one work group can only run on one shader core. However, it seems not the case. 

I got similar latency between a work group with 192 work items and a work-group with 24 work items. But one core should only can run 24 (3x8) work items parallelly.

Therefore, I guess the 192 work items actually run on multiple cores?

Thank you!
