noun explanation

Discrete graphics

Independent graphics card refers to the display chip, video memory and related circuits are made on a single circuit board, which is self-contained and exists as a separate board. It needs to occupy the expansion slot of the motherboard (ISA, PCI, AGP or PCI- E).

Display chip

The GPU's status in the graphics card is equivalent to the CPU 's status in the computer. It is the core of the entire graphics card. The main task is to process the video information input by the system and to construct and render it.

Video memory

Video memory, also called frame buffer, is used to store rendering data processed or about to be extracted by the graphics chip. Just like the computer's memory, video memory is the component used to store graphics information to be processed.

Display chip bit width

The display chip bit width refers to the bit width of the internal data bus of the display chip, that is, the number of data transmission bits used inside the display chip. The larger the bit width, the faster the computing power and data throughput capacity that can be provided.

Memory bandwidth

Video memory bandwidth refers to the data transmission rate between the display chip and video memory. It is measured in bytes / second. Memory bandwidth is one of the most important factors in determining the performance and speed of the graphics card.

Memory speed

The video memory speed is the speed of the repetition period of the clock clock. The faster the video memory speed, the greater the amount of data exchanged per unit time. The clock cycle of the video memory is generally in ns (nanoseconds), and the operating frequency is in MHz.

Memory type

The type of video memory is the type of memory used by the graphics card. It can also be said to be algebraic. There are two types of GDDR5 and GDDR3. GDDR5 can provide more than double the frequency of GDDR3, and it can provide greater bandwidth.

PCI Express 3.0 16X

The PCI-E 3.0 specification improves the data transmission rate to 8GHz | 8GT / s and maintains backward compatibility with PCI-E 2.x / 1.x. It continues to support 2.5GHz and 5GHz signal mechanisms, and sixteen channels (x16) The two-way bandwidth is up to 32GB / s.

Graphics output port

The input and output video model interfaces provided by the graphics card include VGA interface, DVI interface, HDMI interface, and DP interface.
