AnTuTu 8 benchmark

AnTuTu 8 Benchmark đo hiệu suất của một SoC. AnTuTu đánh giá chuẩn CPU, GPU, Bộ nhớ cũng như UX (Trải nghiệm người dùng) bằng cách mô phỏng việc sử dụng trình duyệt và ứng dụng. AnTuTu có thể benchmark bất kỳ CPU ARM nào chạy trên Android hoặc iOS. Không thể so sánh trực tiếp các thiết bị nếu điểm chuẩn đã được thực hiện trong các hệ điều hành khác nhau.

A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.

With integrated graphics you don’t need to buy a separate graphics card.

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

The clock speed of the graphics processing unit (GPU).

DirectX is used in games, with newer versions supporting better graphics.

The fifth-generation wireless technology delivers higher speeds and lower latency than the previous, fourth-generation tech.

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

OpenGL ES is used for games on mobile devices such as smartphones. Newer versions support better graphics.

Some apps use OpenCL to apply the power of the graphics processing unit (GPU) for non-graphical computing. Newer versions introduce more functionality and better performance.

Performance

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.

More threads result in faster performance and better multitasking.

Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life.

Heterogeneous Multi-Processing (HMP) is a more advanced version of big.LITTLE technology. In this setup, a processor can utilize all cores at the same time, or just a single core for low-intensity tasks. This can provide powerful performance or increased battery life respectively.
