General info
1.Has integrated graphics
Qualcomm Snapdragon 855
With integrated graphics you don’t need to buy a separate graphics card.
2.Supports 64-bit
Qualcomm Snapdragon 855
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.
3.semiconductor size
7nm
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.
4.DirectX version
12
DirectX is used in games, with newer versions supporting better graphics.
5.OpenGL ES version
3.2
OpenGL ES is used for games on mobile devices such as smartphones. Newer versions support better graphics.
6.OpenCL version
2
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
1.CPU speed
1 x 2.84GHz & 3 x 2.42GHz & 4 x 1.8GHz
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.
2.CPU threads
8
More threads result in faster performance and better multitasking.
3.Uses big.LITTLE technology
Qualcomm Snapdragon 855
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 e-mail will use the less powerful cores to maximize battery life.
4.Uses HMP
Qualcomm Snapdragon 855
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.
Memory
1.RAM speed
2133MHz
It can support faster memory, which will give quicker system performance.
2.maximum memory bandwidth
31.79GB/s
This is the maximum rate that data can be read from or stored into memory.
3.memory channels
4
More memory channels increases the speed of data transfer between the memory and the CPU.
4.maximum memory size
16GB
The maximum amount of memory (RAM) supported.
5.Supports ECC memory
Qualcomm Snapdragon 855 (ARM Cortex-A76)
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
Features
1.Has integrated LTE
Qualcomm Snapdragon 855
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.download speed
2000MBits/s
The download speed is a measurement of the internet connection bandwidth, representing the maximum data transfer rate at which a device can access online content.
3.Has dynamic frequency scaling
Qualcomm Snapdragon 855 (ARM Cortex-A76)
Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.
4.Has NX bit
Qualcomm Snapdragon 855 (Qualcomm Kryo 485)
NX bit helps protect the computer from malicious attacks.
5.Supports hardware-assisted virtualization
Qualcomm Snapdragon 855 (ARM Cortex-A76)
It is easier to obtain better performance when using virtualization if it is hardware-assisted.
6.Has out-of-order execution
Qualcomm Snapdragon 855 (ARM Cortex-A76)
Out-of-order execution is used in CPUs to make use of instruction cycles that would normally be wasted due to delays.
Miscellaneous
1.Bluetooth version
5
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
