General info

1.Supports 64-bit
Qualcomm Snapdragon 660
Qualcomm Snapdragon 820 MSM8996
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.
2.Has integrated graphics
Qualcomm Snapdragon 660
Qualcomm Snapdragon 820 MSM8996
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.
4.GPU clock speed

650MHz

624MHz

The graphics processing unit (GPU) has a higher clock speed.
DirectX is used in games, with newer versions supporting better graphics.
6.has 5G support
Qualcomm Snapdragon 660
Qualcomm Snapdragon 820 MSM8996
The fifth-generation wireless technology delivers higher speeds and lower latency than the previous, fourth-generation tech.
OpenGL ES is used for games on mobile devices such as smartphones. Newer versions support better graphics.
8.GPU turbo

600MHz

Unknown. Help us by suggesting a value. (Qualcomm Snapdragon 820 MSM8996)

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
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

4 x 2.2GHz & 4 x 1.84GHz

2 x 2.15GHz & 2 x 1.6GHz

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.
3.Uses big.LITTLE technology
Qualcomm Snapdragon 660
Qualcomm Snapdragon 820 MSM8996
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.
4.Uses HMP
Qualcomm Snapdragon 660
Qualcomm Snapdragon 820 MSM8996
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.
