PRO W7900 FAQ

What is the largest model the PRO W7900 can run?

Qwen2.5 72B Instruct (72.7B) is the largest at 4-bit or better: at Q4_K_S it uses 46.6 GB of 48 GB, and runs at about 12.4 tok/s.

Can the PRO W7900 run Qwen3.8 27B?

Yes. Qwen3.8 27B fits at Q4_K_M, using 17.9 GB of 48 GB, and it is the best model that runs well on this card.

Can the PRO W7900 run 120B MoE models?

No. GPT OSS 120B needs 70.8 GB at Q4, more than the 48 GB on this card.

How many tokens per second does the PRO W7900 give?

About 29.8 tok/s on Qwen3.8 27B at Q4_K_M, with the first token after 8.4 s on a 4K-token prompt.

What power supply does the PRO W7900 need?

Plan a 600 W PSU (2× the 295 W TDP).

Is 48 GB enough for coding and agents?

Yes for coding: Qwen3.8 27B, the best of the 10 coding models that fit, runs at about 30 tok/s. For agents, not yet: no agent-scored model fits in less than 96 GB.
