General info
Supports 64-bit
✔Mediatek Helio G99
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.
Has integrated graphics
✔Mediatek Helio G99
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.
GPU clock speed
950 MHz
The clock speed of the graphics processing unit (GPU).
has 5G support
✖Mediatek Helio G99
The fifth-generation wireless technology delivers higher speeds and lower latency than the previous, fourth-generation tech.
GPU turbo
Unknown. Help us by suggesting a value.
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
DirectX version
DirectX 11
DirectX is used in video games, with newer versions supporting better graphics and features. The latest version is DirectX 12 Ultimate, which includes support for ray tracing, mesh shaders, and variable rate shading (VRS).
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
CPU speed
2 x 2.2 GHz & 6 x 2 GHz
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.
CPU threads
8 threads
More threads result in faster performance and better multitasking.
Uses big.LITTLE technology
✔Mediatek Helio G99
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.
Uses HMP
✔Mediatek Helio G99
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.
turbo clock speed
Unknown. Help us by suggesting a value.
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
L2 cache
Unknown. Help us by suggesting a value.
A larger L2 cache results in faster CPU and system-wide performance.
L1 cache
Unknown. Help us by suggesting a value.
A larger L1 cache results in faster CPU and system-wide performance.
clock multiplier
Unknown. Help us by suggesting a value.
The clock multiplier controls the speed of the CPU.
L3 cache
Unknown. Help us by suggesting a value.
A larger L3 cache results in faster CPU and system-wide performance.
Memory
RAM speed
4266 MHz
It can support faster memory, which will give quicker system performance.
DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.
The maximum amount of memory (RAM) supported.
maximum memory bandwidth
17.1 GB/s
This is the maximum rate that data can be read from or stored into memory.
memory channels
Unknown. Help us by suggesting a value.
More memory channels increases the speed of data transfer between the memory and the CPU.
eMMC version
Unknown. Help us by suggesting a value.
A higher version of eMMC allows faster memory interfaces, having a positive effect on the performance of a device. For example, when transferring files from your computer to the internal storage over USB.
Supports ECC memory
✖Mediatek Helio G99
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
Has integrated LTE
✔Mediatek Helio G99
The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
download speed
650 MBits/s
This is the maximum download speed supported. In reality, the download speed will usually be lower, as it will be affected by other factors (such as your home/mobile network speeds).
upload speed
150 MBits/s
This is the maximum upload speed supported. In reality, the upload speed will usually be lower, as it will be affected by other factors (for example your home/mobile network speeds).
Has TrustZone
✖Mediatek Helio G99
A technology integrated into the processor to secure the device for use with features such as mobile payments and streaming video using digital rights management (DRM).
uses multithreading
✖Mediatek Helio G99
Multithreading technology (such as Intel's Hyperthreading or AMD's Simultaneous Multithreading) provides increased performance by splitting each of the processor's physical cores into virtual cores, also known as threads. This way, each core can run two instruction streams at once.
Has NX bit
✖Mediatek Helio G99
NX bit helps protect the computer from malicious attacks.
bits executed at a time
Unknown. Help us by suggesting a value.
NEON provides acceleration for media processing, such as listening to MP3s.
VFP version
Unknown. Help us by suggesting a value.
Vector Floating-Point (VFP) is used by the processor to deliver increased performance in areas such as digital imaging.
front-end width
Unknown. Help us by suggesting a value.
The CPU can decode more instructions per clock (IPC), meaning that the CPU performs better
