NVIDIA GeForce RTX 3080, AI & Machine Learning Benchmarks & Specs

10GB · AI Score 2.3/100 · first-party measured on 12 AI workloads

2.3 AI Score ✓ Measured

Every number on this page is first-party: NVIDIA GeForce RTX 3080 was run on our pinned 12-workload AI suite on 2026-07-11, with under 0.5% run-to-run variance. On Llama 3.1 8B (Q4_K_M) NVIDIA GeForce RTX 3080 delivers about 125.85 tokens/sec. Llama 3.3 70B does not fit. It needs roughly 42GB and this card has 10GB. For image generation, SDXL runs at 2.38 it/s, while FLUX.1-dev won't fit at BF16 (needs ~26GB). 9 of the 12 workloads won't fit on 10GB at the tested precision, Qwen2.5-Coder 14B, Qwen3 32B, Llama 3.3 70B, Z-Image Turbo and others. We publish those as hard gates rather than quietly dropping to a smaller quant.

Bench notes: from the person who ran it

The 3080 sat at exactly its 320W limit on Llama 8B, it uses everything it's given. The thing that surprised me is how little the 10GB buys you over the 8GB cards for AI: still 8 of 12 workloads gated. One run (Qwen2.5-Coder 14B) came back as a fail that shouldn't have been, so that one's flagged until I re-run it. Quick note on the setup: all my AI benchmarking was done on rented cloud GPUs, I used all three of Vast.ai, RunPod and Modal depending on which had the card, and they all have their pros and cons. Same pinned harness on every run, and everything here got double-checked before it went up.

How we measured this. Every result comes from our own pinned, reproducible AI suite, 12 workloads: the Qwen3-4B to Llama-70B LLM ladder (llama.cpp, Q4_K_M), SDXL / Z-Image / FLUX-dev generation, FLUX-Kontext / Qwen-Edit editing, and LTX / Wan video, run first-party on rented hardware with under 0.5% run-to-run variance. Peak VRAM, power draw, temperature and tokens-per-watt are captured per workload. “Won’t fit” rows are real data: where a model exceeds the card’s VRAM at the tested precision we record a hard gate rather than silently dropping to a smaller quant.

The silicon

Transistor density45 million per mm²

Denser than 49% of the 76 cards we have silicon data for. Density is the clearest measure of what a process node bought: a card that gained it without growing the die got its speed from the fab rather than the architecture.

Rent or buy?

This card is $699 to buy. The cheapest listed rate on Vast.ai is $0.029/hour, but that is the floor: we budget $0.035/hour, a 20% premium, because idle time, storage and unavailable cheap instances all land on the same bill. At that rate buying wins after 20,086 GPU-hours. Below it you are paying for idle silicon.

At hobby usage this card is very unlikely to pay for itself before it is superseded. Rent it. Rental figures include a 20% premium over the cheapest listed rate. Ignores electricity, resale and the fact that a rented card can be a newer one tomorrow.
