NVIDIA · Blackwell · 16 GB · Qwen3.8 27B · Q4_K_M: ~12 tok/s with RAM offload

NVIDIA GeForce RTX 5080 16GB

A gaming flagship with only 16 GB: a little faster than the 5070 Ti and no bigger, so for local models it is mostly a premium for the same capacity. Worth it only if the card does double duty for games.

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.
