VRAM, or video random access memory, is the dedicated high-speed memory on a graphics processing unit (GPU) used for storing and manipulating visual and computational data. Unlike system RAM, VRAM is optimized for the parallel workloads that GPUs excel at — rendering graphics, running neural network inference, and processing video frames. For AI-powered tools like VidNo, VRAM is the single most important hardware specification. The voice cloning model, TTS synthesis engine, and video processing operations all compete for VRAM during pipeline execution. Models must fit entirely in VRAM to run efficiently; if they exceed available memory, the system falls back to slower system RAM or fails entirely. VidNo's recommended minimum is 8GB of VRAM (NVIDIA RTX 3070 or equivalent), which comfortably handles voice synthesis and standard video rendering. For batch processing or higher-resolution output, 12GB or more (RTX 4070 Ti and above) provides headroom for concurrent operations and faster throughput.
