Ranking updated on 09/10/2026

The RTX 3080 10 GB (GDDR6X, 760 GB/s) remains highly capable in 2026. 10 GB limits 13B models in Q4 (~8 GB leaves little room for context), but 7–9B Q5 and Mistral 7B FP16 run excellently.

Ranking methodology

Filter: Q4_K_M ≤ 9 GB. Bonus: 7–9B (10 GB peak). 760 GB/s = solid.

Criteria considered:

  • Q4_K_M ≤ 9 GB
  • 10 GB soft limit
  • Mistral 7B FP16 or Q8
  • GDDR6X 760 GB/s

The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.

Frequently asked questions

RTX 3080 10 GB in 2026: still relevant?

Yes for 7-9B in Q5/Q8 (Mistral 7B Q8 = ~7.5 GB) at 50+ tok/s. For 13-14B, you need Q4 with little headroom. See guide.

3080 10 GB vs. 4070 12 GB?

3080 = 760 GB/s, 4070 = 504 GB/s. 3080 ~50% faster. But the 4070 has 12 GB (Qwen 3 14B Q4 OK). Depending on whether speed or VRAM is the priority. See RTX 4070.

Which quantization for a 3080 10 GB?

Q8 for 7B (near-FP16 quality, ~7.5 GB). Q5_K_M for 8–9B (~6–7 GB). Avoid Q4 unless you want to attempt a 13B (~8 GB, little headroom).

Used 3080 10 GB: how much?

~€350-400 in France. For LLMs, a used 3090 (~€650) remains better if you're on a budget. See RTX 3090.
