Can the Radeon RX 7900 XTX run Kimi K2 Instruct?
Does not fit at Q4_K_M.
Kimi K2 Instruct is 1000B parameters (MoE; all experts resident). At Q4_K_M the weights are about 558.8 GiB; with the 1.5 GiB runtime reserve that is 560.3 GiB against the card's 24GB, about 536.3 GiB more than the card has.

Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
Not this card. These fit it comfortably at Q4.
Nothing in the consumer catalog fits Kimi K2 Instruct at Q4 on a single card; this is multi-GPU or datacenter territory, or a job for hosted inference (see PicksByModel for per-token pricing).
