RTX 5090 FAQ

Is the RTX 5090 still worth it in 2026?

At ≈$5,376 you get 3.4 tok/s per $100 on Qwen3.5 9B, which ranks 7th of the 7 cards compared here; it is also the fastest out of 6 cards with 24–32 GB. It runs 27–31B and 35B MoE models well; 70B doesn't fit in 32 GB.

What is the largest model the RTX 5090 can run?

Qwen3.6 35B A3B (36.0B) is the largest at 4-bit or better: at Q4_K_M it uses 22.0 GB of 32 GB, and runs at about 213 tok/s.

Can the RTX 5090 run Qwen3.8 27B?

Yes. Qwen3.8 27B fits at Q4_K_M, using 17.9 GB of 32 GB, and it is the best model that runs well on this card.

Can the RTX 5090 run 70B models?

No. Llama 3.3 70B Instruct needs 51.3 GB at Q4, more than the 32 GB on this card.

How many tokens per second does the RTX 5090 give?

About 66.9 tok/s on Qwen3.8 27B at Q4_K_M, with the first token after 2.4 s on a 4K-token prompt.

What power supply does the RTX 5090 need?

Plan a 1150 W PSU (2× the 575 W TDP).

Is 32 GB enough for coding and agents?

Yes for coding: Qwen3.8 27B, the best of the 10 coding models that fit, runs at about 67 tok/s. For agents, not yet: no agent-scored model fits in less than 96 GB.

Is renting cheaper than buying an RTX 5090?

Rent from $0.50/hr. Renting costs as much as buying after ≈10,800 hours (≈7.4 years at 4 h a day).
