AMD Radeon RX 9070 XT

VRAM (Video RAM)

Dedicated memory on a graphics card used to store textures, frame buffers, and render data. More VRAM allows higher resolutions and more detailed textures.

GPU (Graphics Processing Unit)

A specialized processor designed for parallel computation, primarily used for rendering graphics but increasingly important for AI and compute workloads.

Ray Tracing

A rendering technique that simulates how light physically behaves — bouncing, reflecting, and refracting — to produce photorealistic lighting, shadows, and reflections in games.

FSR (FidelityFX Super Resolution)

AMD's upscaling technology that boosts frame rates by rendering at lower resolution and reconstructing detail. FSR 4 uses AI on RDNA 4 hardware; older versions work on any GPU.

PCIe (PCI Express)

The high-speed interface connecting GPUs, SSDs, and expansion cards to your CPU and motherboard. Each generation doubles bandwidth per lane.

Memory Bandwidth

The rate at which data can be read from or written to memory, measured in GB/s. Critical for GPU performance and AI workloads. Determined by memory type, bus width, and clock speed.
