Browse all terms →GPU (Graphics Processing Unit)
A specialized processor designed for parallel computation, primarily used for rendering graphics but increasingly important for AI and compute workloads.
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.
Ray Tracing
A rendering technique that simulates how light physically behaves — bouncing, reflecting, and refracting — to produce photorealistic lighting, shadows, and reflections in games.
DLSS (Deep Learning Super Sampling)
NVIDIA's AI-powered upscaling technology that renders games at lower resolution and uses neural networks to reconstruct near-native image quality at much higher frame rates.
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.
CUDA Cores
NVIDIA's term for the parallel processing units in their GPUs. More CUDA cores generally means more rendering and compute power. AMD's equivalent are Stream Processors.
