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.
Floating-point performance is a measurement of the raw processing power of the GPU.
Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
A higher memory bandwidth means the memory can be accessed faster and therefore data can be retrieved quicker, having a positive effect on the performance.
You can easily connect an external hard drive via USB if you need more space.
The graphics processing unit (GPU) has a higher clock speed.
Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.
The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
