Ranking methodology

Filter: models whose Q4_K_M fits under 14 GB. Bonus: 7–14B (peak 5080) and 13–24B at the limit. GDDR7 bandwidth of 960 GB/s = ~30% gain vs 4080.

Criteria considered:

  • Q4_K_M ≤ 14 GB
  • 13–14B smoothly in Q5/Q6
  • Tokens/sec ≥ 50 on 7B
  • GDDR7 boost vs. 4080

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

Frequently asked questions

RTX 5080 vs. RTX 4080?

Same 16 GB of VRAM. The 5080 is 25–30% faster on the same models thanks to GDDR7 (960 vs 736 GB/s) + the Blackwell Neural Engine. Mistral Small 24B Q4: 5080 ~38 tok/s vs 4080 ~28 tok/s. See RTX 4080.

Can you run 30B on a 5080?

Mistral Small 24B Q4 (~13 GB) works at 35-40 tok/s. Qwen 3 32B Q3_K_M (~14 GB) is borderline, with degraded quality. For 30-32B in comfortable Q4, target RTX 5090 32 GB. See RTX 5090.

Which quantization on 5080?

Q5_K_M for 7–9B (maximum quality, ~7 GB). Q4_K_M for 13–24B (Mistral Small 24B). Q6_K for 13–14B (Qwen 3 14B ~12 GB) is ideal.

RTX 5080 or Mac Studio M4 Max 64 GB?

M4 Max Studio = silence + 64 GB (smooth 70B Q4). 5080 = pure speed on 7-24B (35-50 tok/s). If you want 70B locally, Mac Studio. For speed on 7-24B, RTX 5080. See Mac Studio.
