General info
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).
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.
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
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.

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

Still a great chipset for being 8 years old

The Exynos 7420 inside of my Galaxy S6 edge+ still holding well basic tasks, and some games with medium graphics such as Call of Duty, the Exynos 7420 isn't a flagship processor anymore but still way better than those new low-end chipsets, example Galaxy A03/A03s processor that have bad Mediatek chipsets or the Qualcomm 400 series chipsets, the Exynos 7420 still more powerful than those chipsets, the only downside is the efficiency of this processor, this processor is based on the 14 nanometer architecture process in his time was good, but now isn't good, apart from that the Exynos 7420 has aged very well, I can play PUBG at HDR/60fps with GFX tool, and can run asphalt 9, very satisfied with the performance of this chipset except with the efficiency for being 8 years old.

I have a Samsung Note 5 and it comes with the Exynos 7420 processor. Even though the Samsung Note 5 is a five-year-old phone, I dare say it performs better than some of today's mid-range phones. In short, this processor is very good.
