1. Apu: APU (Accelerated Processing Unit), whose Chinese name is Accelerated Processor, is a product of AMD's fusion concept. For the first time, it makes the processor and the unique display core on a single chip. It has the processing performance of both high-performance processors and the latest independent graphics card, supports DX11 games and the latest application of "accelerated computing", and greatly improves the operating efficiency of computers, Realize the real integration of CPU and GPU.
2. CPU: Central Processing Unit (CPU) is the computing core and control core of a computer. CPU、 Internal memory and input/output devices are the three core components of electronic computers. Its function is mainly to interpret computer instructions and process data in computer software. CPU is composed of arithmetic unit, controller and register, as well as data, control and status bus to realize their connection. The operating principle of almost all CPUs can be divided into four stages: Fetch, Decode, Execute, and Writeback. The CPU takes instructions from memory or cache memory, places them in instruction registers, decodes the instructions, and executes the instructions. The so-called computer programmability mainly refers to the programming of CPU.
So much for the difference between Apu and CPU.
