I have the mac mini, cpu is intel i7-4578U with Intel Iris 51000 whose max clock is 1275MHz. I find that GPU has been locked the clock, GPU clock is 750MHz. So I install the window OS in the mac mini. I found that the GPU clock just boost 800MHz when I run the OpenCL code, But for the oridinarily using, GPU can boost to the max clock. My question is that why the GPU can't boost to the max clock when I run the OpenCL code ?
