NVIDIA · Ampere · 12 GB · Qwen3.8 27B · Q4_K_M at 8K context: ~5.6 tok/s with RAM offload

NVIDIA GeForce RTX 3080 Ti 12GB

Nearly a 3090's bandwidth with half its memory: 12 GB at 912 GB/s. An 8B model at Q8 or a 14B at Q4 runs fast, and anything bigger does not fit. Cheap because gamers moved on.

At $0.12 an hour on Vast.ai, the $595 a used one costs on eBay buys about 4,900 hours of rental: 7 months around the clock, or 20 months at 8 hours a day. Use it more than that and buying comes out ahead; your power bill pushes that point later, resale value pulls it earlier.

What it runs

For each model, grouped by vendor with the newest first: the largest quant that fits with 8K of context and the estimated speed for one user, at 8K and at 32K of context. On a card, a model too big for its memory can still run with part of the weights in system RAM; we assume 64 GB, and the speed shown accounts for it. The model you picked on the ladder is highlighted. Estimates from the spec sheet, not measurements: see how we estimate.
