RTX 5070 for local LLMs — what fits in 12 GB & the real cost

Rent a RTX 5070 from $0.22/hr ($0 markup, as of 2026-07-02). 253 of the 445 models in our catalog fit its 12 GB — plus the honest own-vs-rent-vs-API math, electricity and amortization included.

Three honest ways to run AI on a RTX 5070

• Own it: buy the card and pay electricity + amortization — local is real money, not "$0".
• Rent it: from $0.22/GPU-hr on your own vendor account (as of 2026-07-02, $0 markup — we never resell compute).
• Skip it: run a comparable open model through your own API key, paying per million tokens (prices as of 2026-07-06).

• Vast.ai: $0.22/GPU-hr — vendor's own price as of 2026-07-02; you pay them directly.

Own a RTX 5070 vs rent it — the honest math

• NVIDIA RTX 5070 12GB: street price $636.00 (as of 2026-07-06; videocardprices.com daily retail tracker, retrieved 2026-07-06 — lowest new listing $635.99 (Amazon); launch MSRP $549) → $0.5808/day amortized over 3 years.
• Electricity ≈ $0.1635/1M tokens at 250 W and $0.19/kWh (EIA Electric Power Monthly Table 5.6.A — U.S. residential average, Apr 2026, as of 2026-07-02), assuming ~80 tok/s (8B-class model at Q4).
• vs renting: owning wins above ~3.4 active hours/day at the cheapest logged rate ($0.22/hr).
• vs API: Llama 3.1 8B Instruct at $0.03/1M (as of 2026-07-06) is cheaper than the electricity alone — owning never breaks even at any volume.
