Graphic Cards (GPU) with important points, MCQs, and previous year questions from exams like SSC, Bank, RRB, JKSSB, etc.
✅ Graphic Card (GPU) – Important Notes for Exams
📘 Definition:
A graphics card, also called a GPU (Graphics Processing Unit), is a hardware component that renders images, videos, and animations for display. It is mainly responsible for processing and accelerating graphics and visual output.
🔍 Key Functions:
-
Renders 2D and 3D images and videos.
-
Offloads graphics tasks from CPU for better performance.
-
Essential for gaming, video editing, CAD, and AI tasks.
-
Enhances display resolution, color depth, and frame rates.
🔧 Types of Graphic Cards:
| Type | Description |
|---|---|
| Integrated GPU | Built into the CPU or motherboard (e.g., Intel UHD) |
| Dedicated GPU | Separate card installed in PCIe slot (e.g., NVIDIA) |
| External GPU (eGPU) | Separate box connected via Thunderbolt/USB-C |
🧠 Major GPU Manufacturers:
-
NVIDIA – Popular for gaming (GeForce), AI (Tesla, Quadro).
-
AMD – Radeon series.
-
Intel – Integrated graphics like Intel Iris or UHD.
🖥️ Key Specs of a GPU:
-
VRAM: Video memory (like RAM for GPU).
-
Core Clock Speed: Measures GPU processing speed.
-
CUDA Cores / Stream Processors: Parallel processing units.
-
DirectX/OpenGL Support: APIs for rendering.
🎮 Common Uses:
