What is a graphics card (external CPU)? How does it work?


The graphics card is a hardware component that manages the computer's graphics operations. Like the processor, the graphics card is also an important part that affects the performance of the computer. Essentially, it is responsible for providing an image on the computer screen. It has a GPU, i.e. a graphics processor specially designed for this purpose. The GPU accelerates graphical operations such as rendering 2D and 3D graphics, rendering videos, and running games. In addition, the graphics card has its own memory that is used to temporarily store graphics data. The graphics card is connected to the computer's motherboard and communicates with the processor and other components via the graphics interface. Finally, the monitor ports are used to transmit the rendered image to the monitor. Here are the first organizations that come to mind when “graphics card” is mentioned:

NVIDIA (Nvidia Corporation):

CUDA (Compute Unified Device Architecture): A platform that accelerates common operations using parallel computing capabilities.

RTX (Ray Tracing Technology): Real-time ray tracing technology. This technology provides more realistic lighting, shading and reflections in game graphics.

Tensor Cores: Dedicated hardware unit to accelerate deep learning and artificial intelligence operations.

AMD (Advanced Micro Devices):

Radeon Graphics: AMD's line of graphics cards. Designed for high-performance gaming and professional graphics applications.

RDNA (Radeon DNA): A new architecture for AMD's graphics processors. Offers higher performance and energy efficiency.

Freesync: A technology that prevents screen tearing and frame skipping by synchronizing the graphics card's refresh rate with the monitor's refresh rate.

Intel Corporation:

Intel Iris Xe Graphics: Intel's integrated graphics processors. It offers low power consumption and good performance.

Xe-LP (Low Power): Low power graphics architecture designed for laptops and lightweight portable devices.

Apple (Apple Inc.):

Apple M1 GPU: The integrated graphics unit found in Apple's homegrown ARM-based processors. Offers high performance and energy efficiency.

Qualcomm Incorporated:

Adreno Graphics: Qualcomm's graphics processors used in mobile devices. Offers high performance and low power consumption.
