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

Frequently asked questions

RTX 4080 Super vs 4080?

Even 16 GB. 4080 Super = +5% performance (~7% CUDA cores, slightly faster GDDR6X). Imperceptible difference for most LLMs. Prefer the cheaper used option. See RTX 4080.

4080 Super vs. 5080?

5080 = ~25% faster (GDDR7 vs. GDDR6X) but ~€600 more when new. Used 4080 Super at ~€700 = better value. See RTX 5080.

Llama 70B on a 4080 Super?

No — Q4 (~40 GB) does not fit in 16 GB. Q2_K (~28 GB) does not fit either. For 70B locally on consumer hardware, target RTX 4090/5090 24+ GB or Mac Studio 64+ GB.

LLM sweet spot on a 4080 Super?

Mistral Small 24B Q4 (~13 GB) at 30 tok/s or Qwen 3 14B Q6 (~12 GB) at 50 tok/s. For code, Qwen 2.5 Coder 14B Q5. See code ranking.
