What is a Graphics Card?
A graphics card (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device.
Modern GPUs are very efficient at manipulating computer graphics and image processing, and their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles.

Key GPU Features
VRAM Capacity
Determines how much texture data and assets can be stored for quick access during gaming and rendering.
Clock Speeds
Higher clock speeds generally mean better performance, though architecture efficiency also matters.
Ray Tracing
Advanced lighting technology that simulates real-world light behavior for more realistic graphics.
Upscaling
Technologies like DLSS and FSR improve performance by rendering at lower resolution then upscaling.
Frequently Asked Questions
For 1080p gaming, 6-8GB is sufficient. For 1440p gaming, 8-12GB is recommended. For 4K gaming or content creation, 12GB or more is ideal. Games with high-resolution textures and mods can benefit from even more VRAM. Future-proofing suggests getting more VRAM than you currently need.
NVIDIA generally leads in ray tracing performance and has DLSS technology. AMD often provides better value in traditional rasterization performance and has competitive ray tracing in newer cards. Consider your specific needs: if ray tracing and AI features are important, NVIDIA might be better; if pure performance per dollar matters more, AMD could be the choice.
Reference cards are the base design from NVIDIA or AMD. Custom cards from partners like ASUS, MSI, and Gigabyte often feature improved cooling solutions, higher clock speeds, better power delivery, and different aesthetics. Custom cards typically offer better performance and cooling but may cost more than reference models.
High-end graphics cards can consume significant power. Check the recommended PSU wattage for your chosen GPU and ensure your power supply has the necessary PCIe power connectors. As a general rule, budget cards need 450-550W, mid-range 550-650W, high-end 650-750W, and enthusiast cards 750W+.
Ray tracing significantly improves lighting, shadows, and reflections for more realistic graphics. However, it's computationally expensive and can dramatically reduce performance. The importance depends on your priorities: if visual fidelity is paramount and you have a high-end card, ray tracing is worthwhile. For competitive gaming where frame rates matter more, it may be better disabled.
