(1) Structure
- GPU Chip: Performs graphics processing (e.g., NVIDIA RTX, AMD Radeon).
- VRAM (Video Memory): Stores image data (e.g., GDDR6, GDDR6X).
- VRM (Voltage Regulation Module): Ensures stable power delivery.
- Cooling System: Air cooling or water cooling.
(2) Working Principle
- Renders 3D scenes: Computes lighting, shadows, textures from CPU instructions.
- Outputs to display: Converts processed graphics data to video signals (HDMI/DP).
(3) Classification
| Type | Usage | Examples |
|---|---|---|
| Integrated GPU (iGPU) | Basic office work | Intel UHD, AMD Vega |
| Entry-Level GPU | 1080p gaming | GTX 1660, RTX 3050 |
| High-End GPU | 4K gaming, content creation | RTX 4090, RX 7900 XTX |
(4) Classification Reasons
- CUDA cores/Stream processors determine computational power.
- VRAM capacity (e.g., 8GB, 16GB) affects 4K texture rendering.
