Can Used AMD Radeon RX 7900 XT 20GB run Llama, Qwen & DeepSeek? 339 models that fit
339 of the 493 models in the Spanvero catalog fit Used AMD Radeon RX 7900 XT 20GB's 20 GB VRAM (at a sensible quant, 16k context). For each: run it locally ($0 compute + electricity), rent an equivalent GPU ($0 markup, as of 2026-07-09), or pay per-token via your own API key (as of 2026-08-17).
Three honest ways to run each model on Used AMD Radeon RX 7900 XT 20GB
Run it locally: $0 in compute — you pay only electricity (~315 W under load on this card). Local is real money, never a fake "$0".
Rent an equivalent GPU: from a $0-markup vendor rate (as of 2026-07-09) — you rent on your own account and pay the vendor directly; we never resell compute.
Skip the box: run the same model through your own API key, paying per million tokens (prices as of 2026-08-17).

The honest cost of owning Used AMD Radeon RX 7900 XT 20GB
Street price $535.00 (as of 2026-07-04; BestValueGPU eBay used-price tracker, Jul 2026 (~$534.99)) — amortized over 3 years that's ~$0.4886/day whether or not you're generating.
Electricity: ~315 W under sustained inference at $0.1883/kWh (EIA Electric Power Monthly Table 5.6.A — U.S. residential average, Apr 2026, as of 2026-07-02) — the per-1M-token figures above already include this at each model's speed.
Straight talk: for the small models a 20 GB VRAM box runs, hosted APIs are often cheaper per token. Own local for privacy, offline use, and unlimited runs — not to save money on tokens.
Too big for Used AMD Radeon RX 7900 XT 20GB — rent or use an API instead
