What is APU?

By  Herb Dodds 2020-01-03 2108 3

APU, whose full name is "Accelerated Processing Units", is an accelerated processor. It is a product that combines CPU and GPU functions. The two most important processors on a computer merge, complement each other and maximize performance. The Chinese name of APU is accelerated processor, which is the product of the concept of AMD convergence. For the first time, it has the processing performance of a high-performance processor and the latest independent graphics card. It supports the "accelerated computing" of DX11 games and the latest applications, greatly improving the efficiency of computer operation, and realizing the real integration of CPU and GPU. The secret of APU's strong performance lies in its innovative core architecture, the latest video decoding engine, ultra-small chip and ultra-low power design, and strong display performance.

What is APU?

In the final analysis, APU combines the general computing x86 architecture CPU core with the programmable vector processing engine, combining the precise scalar operations that CPU is good at with large-scale parallel vector operations that are traditionally available only in GPU. AMD APU design combines the advantages of CPU and GPU, brings unprecedented flexibility for software developers, and can arbitrarily use the most suitable way to develop new applications. AMD APU connects a programmable x86 CPU and a GPU vector processing architecture on a single silicon chip through a high-performance bus, both of which can read high-speed memory directly. AMD APU also contains some other system components, such as memory controller, Imax O controller, dedicated video decoder, display output and bus interface. The charm of AMD APU is that they contain all the processing power made up of scalar and vector hardware.

APU background introduction

AMD will be divided according to two new processor architectures: "Bulldozer" (Bulldozer) and "Bobcat" (Bobcat). Bulldozer architecture focuses on performance and scalability, oriented to mainstream clients and servers; Bobcat architecture focuses on flexibility, low power consumption and small size, and will be used for low-power devices, small devices, and cloud clients.

The bobcat architecture is the foundation of the Fusion APU fusion processor, and the real products include "Zacate" and "Ontario". The difference between these two products is that the TDP of "Zacate" is 18W, which is mainly aimed at the light and thin PC market, against the ULV (Ultra Low Voltage) series processors of Intel, while the TDP of "Ontario" is 9W, which is mainly aimed at netbooks and Atom series processors. Mejie SY-E350 is the "Zacate" core. What is
