# AnTuTu

AnTuTu (Chinese: 安兔兔; pinyin: ĀnTùTu) is a software benchmarking tool commonly used to benchmark smartphones and other devices. It is owned by Chinese company Cheetah Mobile.

## Operations

The company developing the software is based in Chaoyang District, Beijing, and was cofounded by Chinese entrepreneurs Shào Yīng (邵英) and Liáng Bīn (梁斌). They started multi-platform development, releasing an x86 Linux version in May 2021 and a Windows version with ray tracing support in August 2021.

## Circumvention

The AnTuTu benchmark is so common that some hardware manufacturers have cheated on the benchmark, which made the benchmark unreliable. In response to cheating, AnTuTu created a new benchmark, called AnTuTu X, which made it more difficult for manufacturers to cheat on the benchmark.
Despite the changes introduced by AnTuTu X, cheating continued to be rampant; for instance, in 2021, AnTuTu delisted (and for three months, banned) the Realme GT after evidence was discovered that the phone was found to have used delay tactics in multithreading performance tests, as well as modifying the reference JPEG image for image processing tests.
