2022 Cpu performance ranking ladder

The latest CPU ladder diagram in 2022 is as follows: Apple A 15 Bionic, Snapdragon 855Plus and Huawei Kirin 990.

1, Apple A 15 bionic

Through the combination of 4 efficiency cores and 2 performance cores and 4-core GPU, 8.5 billion transistors are integrated, and the performance is improved by about 20%. Apple calls it the fastest CPU in smartphones and the fastest GPU in smartphones.

2. Snapdragon 855Plus

Compared with the original Snapdragon 855, Snapdragon 855Plus has not changed much, mainly because the frequency of large-core CPU is increased from 2.84 to 2.96GHz, and the frequency of GPU is increased from 585MHz to 672MHz, with the amplitude of 4% and 15% respectively.

3. Huawei Kirin 990

Kirin 990 processor will be manufactured by TSMC's second generation 7 nm process. Although the overall architecture has not changed due to the improvement of technology and the use of V-ray recorder. The overall performance of HiSilicon Kirin 990 processor will be improved by about 10% compared with the previous generation HiSilicon Kirin 980. Hisilicon Kirin 990 processor has built-in Snapdragon 5000 baseband, which is built-in 5G.

Structure of central processing unit

Generally speaking, the structure of CPU can be roughly divided into arithmetic logic unit, register unit and control unit. The so-called arithmetic logic unit can mainly perform related logical operations.

If it can perform shift operations and logical operations, it can also perform fixed-point or floating-point arithmetic operations, address operations and conversion commands. It is a multifunctional arithmetic unit, and the register part is used to temporarily store instructions, data and addresses.

For CPU, it can be regarded as a large-scale integrated circuit, and its main task is to process and process all kinds of data. The storage capacity of traditional computers is relatively small, so it is difficult to process large-scale data and the processing effect is relatively low.
