What is an apu?

APU actually integrates CPU and GPU, and also integrates the north-south bridge of the traditional motherboard to form a single-chip solution.

Its advantage is that it can effectively reduce energy consumption and is suitable for mobile computing. When the computing demand is high, part of the computing power of GPU can assist CPU in computing and improve the operating efficiency of the chip. With the maturity and commercialization of the architecture, the APU with higher performance will be continuously upgraded, and its comprehensive performance will gradually surpass the CPU+GPU scheme.

auxiliary power unit

The full name is: auxiliary power plant. It is a low-power engine, which can provide power and gas for the plane when it is parked on the ground. The engine installed on the wing of the aircraft is not allowed to start when it is parked in the parking stand without the permission of the tower.

When the engine is not started, the energy-consuming components such as air conditioners that need power on the aircraft cannot be moved by the power of aircraft batteries or storage batteries, and the air conditioners do not work very hard. However, it is useless to start the main engine in order to run an air conditioner. Needless to say, when the engine starts, people on the ground are not allowed to get close and will be sucked in.
