Like-new condition, has had a screen protector on and case since it was opened. Has been barely used.

Pulled from a working multi-GPU inference box. I ran a full validation pass before listing. All measured on this exact card, benchmarks below.

VRAM integrity: Wrote and verified unique patterns across 14GB of the 16GB — 0 mismatched words, no bad memory.

Compute: FP32 12.4 / TF32 31.2 / FP16 62.8 / BF16 61.7 TFLOPS · 390 GB/s bandwidth · PCIe 23.7 GB/s up, 27.1 GB/s down at full x16

12-min sustained load: Held 56.6 TFLOPS FP16 for the full run, 37,080 iterations, zero errors. Power pinned at 139-140W (full TDP) throughout. Temp plateaued at 90-91C with 0.0C drift over the final 8 min. Under load: SW Power Cap active, thermal slowdown NOT active — it's power-limited, not heat-limited. Lifetime firmware counters read 0us thermal slowdown and 0us power braking, so it has never thermally throttled in its life. Known-answer matmul recomputed correctly while fully heat-soaked.

LLM inference (vLLM, Qwen2.5-7B AWQ, 4096 ctx): 78.8 tok/s single stream · 484 tok/s at 8 concurrent · 920 tok/s at 16 · 1,964 tok/s at 32. Loads in 36s, 14.2GB resident, 73-80C.
