Q4_K_M vs Q5_K_M vs Q6_K vs Q8_0. A practical decision guide for picking the right GGUF quant on consumer GPUs.
VRAM decides your GGUF quant, not vibes. How I assign Q4, Q5, Q8 across an 8GB 3070, 16GB 5070 Ti, and 32GB 5090.
Given your GPU, which GGUF quant do you actually pick? The VRAM math, a card-by-card table, and the quality tradeoff in plain terms.
Q4_K_M cuts model size 75% with barely any quality loss — but Q5, Q6, and Q8 each win in specific cases. We benchmarked every quant level on real hardware. Here's which to pick. (2026)
Real costs, real tools, no fluff. M-F when I ship, publish, or learn something worth sending.
