Kernel Planet

Kernel Planet: "ntelligent Power Sharing (IPS). Core i7-6xx and 7xx chips are MCP (multi-chip packages); both the CPU and GPU/MCH are in the same physical processor package, but not on the same die. This means they share a thermal and power design domain. In many cases, only one of the components will be very busy, and thus generating much heat or drawing much power, and it would be a waste to let any extra thermal or power headroom go unused. IPS allows one component to use more than its share of power or thermal budget so long as the other component is idle enough to allow it. One of the key parts of this technology is so-called “graphics turbo', in other words the capability of the GPU to exceed its default frequency (and therefore thermal and power budget) when possible."
