Max CPU clock with dedicated GPU= 5125MHz
Max CPU clock with integrated graphics= 4900MHz
Why? The total power draw from the CPU and integrated graphics both going full blast is 270W. With the iGPU disabled the power draw is halved. 225MHz might seem excessive but keep in mind we are doubling the power draw which increases the heat significantly within the die.
The reason this test is so good is because it pushes the igpu and cpu to its absolute limits. Conventional tests only test one component at a time, in that scenario I could easily run the same cpu clock I run without iGPU and be stable for hours, meanwhile the power tests would crash it within 5 seconds. The iGPU also sees a 50MHz reduction with this test as opposed to testing both components individually.
