  • What is the relation between Mali shader core and OpenCL work-group

    hiwu
    hiwu

    Hi all:

    I use a RK3288 with mali T760 MP4 board. T760 has 16 shader core.
    (1) Is there 64 shader core (16*4) in mali T760 MP4?
    (2) Does one opencl work-group use more than 1 shader core ?

    Thank you

    -Jack
