AMD Graphics Cards Buyers Guide

What is an AMD Radeon GPU / Graphics Card?

Though many modern CPUs are equipped with integrated graphics, these are only really suitable for gaming at low quality settings at 1080p. In contrast, AMD Radeon graphics cards are far more powerful, providing a far superior gaming experience with high resolution eye-popping graphics.

The GPU (Graphics Processing Unit) and is the main ingredient of a graphics card, the most important component in a gaming PC. A key supplier of graphics cards is AMD, and its range of Radeon GPUs offer something at every imaginable price point. The key specs to look out for when choosing a Radeon graphics card are the number of stream processors, ray accelerators, AI accelerators and amount of memory, with more powerful cards having more of all four.

AMD-GPU-Family

A more powerful graphics card will enable your PC to run games at higher quality settings at a smooth frame rate for a superior gaming experience. The first question you should therefore ask yourself is what monitor do you have or intend to buy so you can choose a graphics card suitable for it. To make this process easier this buyers guide recommends the optimum monitor resolution for each graphics card.

AMD Radeon Special Features

Ray Tracing

The ray accelerators enable real time ray traced graphics in games. Unlike traditional rasterised graphics, ray tracing simulates how light beams and shadows actually work, providing far more rich and realistic graphics.

FidelityFX Super Resolution

FidelityFX Super Resolution is an advanced upscaling technology that increases the frame rate in games. It enables you to ramp up the resolution to enjoy higher quality graphics, without sacrificing performance.

Adrenalin Edition

Adrenalin Edition is a collection of tools that enhance your gaming experience, including performance optimisation, system monitoring and streaming.

Noise Suppression

Noise Suppression technology provides extra clarity when streaming or in a meeting, removing unwanted background noise.
