What does 2GB and 4BG CPU means

A Graphics Card, or a GPU, is a very powerful CPU designed to perform graphical and graphics related calculations. Before I move on to what 2 GB and 4 GB GPU means, I'll first describe why a GPU needs memory.

A CPU or a GPU performs huge number of calculations per second. Whether you are watching a movie, or playing a game or even moving a mouse pointer, everything is calculations in binary inside the CPU and GPU (the GPU is responsible for rendering the display output). So to store results of such huge amount of calculations, and to perform them, the CPU/GPU needs memory. That's what the RAM is- memory for storing and performing all the calculations.

A GPU can be of 2 types- Integrated and Dedicated. An integrated GPU is one which does not have its own memory for performing calculations (for graphics related calculations, especially in a game, a huge amount of memory is needed). Such a GPU utilizes the RAM as its memory. A dedicated GPU, on the other hand, has its own RAM for performing calculations (this memory is faster than the RAM), and by 2 GB/4GB graphics we refer to the amount of dedicated memory the GPU has. In other words, the GPU needs memory to perform all the graphics related calculations and render them. The more amount of dedicated memory the GPU has, the more details it can render (such as higher screen resolution, textures, anti-aliasing). However, the amount of memory does not affect the GPU performance, it merely determines how much details it can render. A graphics card performance depends on other factors, such as its technology, pipelines, number of cores, clock frequency, memory type and frequency etc.

Your user profile is a collection of settings that make the computer look and work the way you want it to.

Locate the C:\Users\Old_Username folder, where C is the drive that Windows is installed on, and Old_Username is the name of the profile you want to copy files from.

Select all of the files and folders in this folder, except the following files:

Ntuser.dat
Ntuser.dat.log
Ntuser.ini
