A unified thermal core.

The new Mac Pro packs an unprecedented amount of power in an unthinkable amount of space. A big reason we were able to do that is theingenious unified thermal core. Rather than using multiple heat sinks and fans to cool the processor and graphics cards, we built everythingaround a single piece of extruded aluminium designed to maximise airflow as well as thermal capacity. It works by conducting heat awayfrom the CPU and GPUs, and distributing that heat uniformly across the core. That way, if one processor isn’t working as hard as theothers, the extra thermal capacity can be shared efficiently between them. No computer has been built this way before. And yet it makesso much sense, it’s now hard to imagine building one any other way.
