Local LLM performance hinges on VRAM, not compute power

Running large language models locally is primarily constrained by VRAM capacity rather than raw compute power. The key factors consuming VRAM are the model's weights and the KV cache, which scales with context length and batch size. Quantization methods like 4-bit GGUF significantly reduce weight memory but have a less proportional impact on the KV cache, making context length crucial for VRAM planning. For hardware, a 24 GB card like the RTX 3090 is recommended for 7B-14B models and comfortably handles 32B models with sufficient context, while larger models may require multiple GPUs or specialized solutions.
