The display chips of mainstream graphics cards are mainly manufactured by NVIDIA (NVIDIA) and AMD (AMD). Graphics cards using NVIDAI display chips are usually called N cards, while those using AMD display chips are called N cards. The graphics card is called an A card.

The graphics cards currently on the market are divided into A cards and N cards:

Differences:

1. A cards use ATI graphics chips, and N cards use NVIDIA graphics cards. Chip

2. N card focuses on 3D performance and speed, while A card focuses on 2D flat image quality.

3. The A-card manufacturer is AMD, and the N-card manufacturer is NVIDIA.

The relationship between ATI and NVIDIA feels similar to the relationship between AMD and INTEL, both of which are industry leaders. , and compete with each other, but ATI has been acquired by AMD. N card products include GeForce Ti series, GeForce FX series, etc. A card products include Radium and X series.

Types, advantages and disadvantages of graphics cards:

1. Integrated graphics card

CPUs equipped with core graphics cards are usually inexpensive. High, while low-end core displays are difficult to handle large games. Integrated graphics is a component that integrates the display chip, video memory and related circuits on the motherboard. There are separate display chips for integrated graphics cards, but most of them are integrated into the Northbridge chip of the motherboard. Some motherboards integrate The graphics card also has video memory installed separately on the motherboard, but its capacity is smaller.

The advantage of integrated graphics is low power consumption and low heat generation. The performance of some integrated graphics cards is already comparable to entry-level independent graphics cards, so many people who like to assemble computers by themselves do not need to spend extra money to purchase them. With a separate graphics card, you can get satisfactory performance. ?

2. Independent graphics card

Independent graphics card means that the display chip, video memory and related circuits are separately built on a circuit board, forming a self-contained whole as an independent board card Yes, it needs to occupy the motherboard's expansion slot (ISA, PCI, AGP or PCI-E).

The advantage of a discrete graphics card is that it has separate video memory, which generally does not occupy system memory. It is also technically much more advanced than an integrated graphics card, but its performance is definitely not worse than an integrated graphics card, and it is easy to upgrade the hardware of the graphics card.

The disadvantages of independent graphics cards are that the system power consumption is increased, the heat is also larger, it requires additional funds to purchase the graphics card, and at the same time (especially for laptops) it takes up more space. Since different graphics card performances have different requirements for graphics cards, independent graphics cards are actually divided into two categories, one is entertainment graphics cards specially designed for games, and the other is professional graphics cards used for drawing and 3D rendering. ?

3. Core graphics card

Core graphics card is the new generation graphics processing core of Intel products. Different from previous graphics card designs, Intel relies on its advanced technology in the processor manufacturing process. And a new architectural design integrates the graphics core and processing core on the same substrate to form a complete processor.

This design integration of the intelligent processor architecture greatly reduces the data turnover time between the processing core, graphics core, memory and memory controller, effectively improves processing performance and significantly reduces the overall power consumption of the chipset. It helps reduce the size of core components and provides greater design options for notebooks, all-in-one computers and other products.
