About the RTX 4090

The RTX 4090 is the quickest card in the 24 GB class: it runs 27–31B and 35B MoE models well. It is power-hungry for its speed, and pricier per token than most of the cards compared at ≈$3,000 used. Ada Lovelace generation, released 2022.

RTX 4090 strengths and weaknesses

Strengths

  • Runs 35B MoE models: Qwen3.6 35B A3B at 151 tok/s in 22 GB
  • Room for long context: Qwen3.8 27B at Q4 uses 17.9 GB, leaving 6.1 GB free

Weaknesses

  • 70B models don't fit: Llama 3.3 70B Instruct needs 51.3 GB at Q4 vs 24 GB here
  • 450 W under load: Plan a 900 W PSU; ≈$99 a year at 4 h a day
  • Used prices above MSRP: ≈$3,000 used vs its $1,599 MSRP (+88%)

Speed per dollar and per watt

On Qwen3.5 9B (9B params) at Q4_K_M. New prices are compared with new, used with used. The last two columns are the speed you get per $100 of price and per 100 W of board power; higher is better. The RTX 4090 has no new price, so the New view shows it at its MSRP.

RTX 4090 FAQ

Is the RTX 4090 still worth it in 2026?

At ≈$3,000 used you get 3.4 tok/s per $100 on Qwen3.5 9B, which ranks 7th of the 8 cards compared here; it is also the fastest out of 5 cards with 24 GB. It runs 27–31B and 35B MoE models well; 70B doesn't fit in 24 GB.

What is the largest model the RTX 4090 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 24 GB, and runs at about 151 tok/s.

Can the RTX 4090 run Qwen3.8 27B?

Yes. Qwen3.8 27B fits at Q4_K_M, using 17.9 GB of 24 GB, and it is the best model that runs well on this card.

Can the RTX 4090 run 70B models?

No. Llama 3.3 70B Instruct needs 51.3 GB at Q4, more than the 24 GB on this card.

How many tokens per second does the RTX 4090 give?

About 37.6 tok/s on Qwen3.8 27B at Q4_K_M, with the first token after 3.1 s on a 4K-token prompt.

What power supply does the RTX 4090 need?

Plan a 900 W PSU (2× the 450 W TDP).

Is 24 GB enough for coding and agents?

Yes for coding: Qwen3.8 27B, the best of the 9 coding models that fit, runs at about 38 tok/s. For agents, not yet: no agent-scored model fits in less than 96 GB.

Is renting cheaper than buying an RTX 4090?

Rent from $0.34/hr. Renting costs as much as buying after ≈8,800 hours (≈6.0 years at 4 h a day).
