Top specs and features

General info

1.Supports 64-bit
HiSilicon Kirin 940

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 applications.

2.GPU clock speed

650MHz

The graphics processing unit (GPU) has a higher clock speed.

Best

AMD Ryzen 7 2800H

1300MHz

3.semiconductor size

16nm

A smaller size indicates that the process to create the chip is newer.

Best

Apple A12X Bionic

7nm

4.DirectX version

11.2

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

Best

AMD Ryzen 3 3300U

5.OpenGL ES version

3.1

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

Best

Qualcomm Snapdragon 439

3.2

6.OpenCL version

1.2

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

Performance

1.CPU speed

4 x 2.2GHz & 4 x 1.5GHz

Best

MediaTek Helio X30

2 x 2.6 & 4 x 2.2 & 4 x 1.9GHz

2.Uses big.LITTLE technology
HiSilicon Kirin 940

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise 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 maximise battery life.

Memory

1.maximum memory bandwidth

25.6GB/s

This is the maximum rate that data can be read from or stored into memory.

Best

AMD Ryzen 7 2800H

47.68GB/s

2.memory channels

2

More memory channels increases the speed of data transfer between the memory and the CPU.

Best

Features

1.Has integrated LTE
HiSilicon Kirin 940

The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.

2.bits executed at a time

128 (ARM Cortex-A53)

NEON provides acceleration for media processing, such as listening to MP3s.

Best

MediaTek MT6750S

128

3.VFP version

4 (ARM Cortex-A53)

Vector Floating-Point (VFP) is used by the processor to deliver increased performance in areas such as digital imaging.

Best

4.Has dynamic frequency scaling
HiSilicon Kirin 940

Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.

5.Supports hardware-assisted virtualization
HiSilicon Kirin 940

It is easier to obtain better performance when using virtualization if it is hardware-assisted.

6.Has NX bit
HiSilicon Kirin 940

NX bit helps protect the computer from malicious attacks.
