So sánh chip a9 và a9x

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

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.

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.

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

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

eMMC version

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.

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

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

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.

upload speed

Unknown. Help us by suggesting a value. (Apple A9X)

The upload speed is a measurement of the internet connection bandwidth, representing the maximum data transfer rate at which a device can send information to a server or another device.

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).

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.

NX bit helps protect the computer from malicious attacks.

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

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

The CPU can decode more instructions per clock (IPC), meaning that the CPU performs better
