The 8GB VRAM Tier List

Constrained to roughly 5.5GB weight limits, S-Tier models include Qwen 2.5 Coder 7B (Q5_K_M) hitting 75 tokens/sec, and DeepSeek-R1-Distill-Llama-8B for offline chain-of-thought mathematical reasoning.

02

The 12GB Sweet Spot: Running 14B Weights

The 12GB VRAM buffer on the RTX 3060 comfortably houses Qwen 2.5 Coder 14B in Q4_K_M quantization, achieving commercial-grade code generation locally.
