Graphic Random Access Memory

They are memory chips that stores and transports information between themselves, do not determine the maximum performance of the graphics card, but rather a reduced specifications may limit the power of the GPU. There are two types: Dedicated when the graphics card or GPU has to itself those memories, this way is more efficient and gives better results; and shared memory is used as detrimental to the RAM.
