The key difference between integrated graphics cards and RTX cards (NVIDIA's high-end discrete GPUs) lies in their performance, architecture, and use cases:

1. Integrated Graphics Card:

• Built-in: Integrated into the CPU (e.g., Intel UHD, AMD Radeon Vega).

• Shared Memory: Uses system RAM, not dedicated video memory.

• Performance: Suitable for basic tasks like browsing, watching videos, office work, and light photo editing.

• Power Efficient: Consumes less power, good for laptops and budget systems.

• Limitations: Not suitable for heavy gaming, 3D rendering, or AI workloads.

2. RTX Card (e.g., NVIDIA RTX 3060, 4080):

• Dedicated GPU: Separate hardware with its own VRAM (Video RAM).

• Ray Tracing: Real-time ray tracing for realistic lighting, shadows, and reflections.

• AI Features: Supports DLSS (Deep Learning Super Sampling), used in gaming and AI tasks.

• High Performance: Ideal for 4K gaming, video editing, 3D modeling, machine learning, and other GPU-intensive workloads.

• Higher Cost and Power Usage: Requires more power and cooling, and is significantly more expensive.
