Should You Buy an RTX 3090 or Rent One?

An RTX 3090 costs $1,499 at MSRP. You can also rent one by the hour with no commitment. Which is cheaper depends entirely on how many hours you'll genuinely use it: so rather than pretend we know that, this page gives you the break-even maths, a calculator that takes the rate you were actually quoted, and our measured numbers on what the card really does across 12 AI workloads.

Best for: Sustained Qwen3 32B-class work where you'll keep the card genuinely busy.

The RTX 3090 is one of the few AI-capable GPUs you can genuinely choose between owning and renting. It has a retail price ($1,499 MSRP) and it's stocked by GPU cloud providers by the hour. So the question isn't which card. It's whether to put $1,499 on the table at all. That's arithmetic, not opinion, and it turns on one number nobody can tell you in advance: how many hours you'll actually use it. Below is the maths, and a calculator that takes the rate you were actually quoted rather than one we invented.

Three things the calculator can't price, and you should. Ownership only pays on utilisation. Token generation is bound by memory bandwidth, not compute, so a card running one stream at a time leaves most of what you bought idle, our telemetry shows exactly that across the fleet. If your usage is bursty or exploratory, the break-even hours in the table are hours you'll never actually accumulate. Renting doesn't lock you in. The RTX 3090 is what's current today. Buying it is a bet that it stays appropriate for the break-even period, which, on most of the rates above, is measured in years. Renting lets you move to whatever's current when it arrives, and the rate you pay tracks the market rather than your purchase date. Owning isn't only about money. Data that can't leave your building, latency that can't tolerate a network hop, or simply wanting the thing on your desk: none of that shows up in a break-even calculation, and all of it is legitimate. If one of those applies, the arithmetic is a sanity check rather than a decision.

Our verdict

The RTX 3090 is $1,499 to own. At $0.50/hr that's 2,998 hours of rental, 2.9 years at 20 hours a week. Before buying wins. And it's gated out of 4 of our 12 workloads, including Llama 3.3 70B, so rent one for an hour and confirm your model actually loads before you spend anything. Buy it if your usage is sustained and you'll saturate it. Rent it if you're exploring, bursty, or unsure, the arithmetic almost always favours renting until utilisation is high and steady.

FAQ

Is it cheaper to buy or rent an RTX 3090?

It turns entirely on hours used, and the maths is simple: $1,499 divided by your hourly rate gives the hours of rental you'd have to buy before owning is cheaper. At $0.50/hr that's about 2,998 hours, roughly 2.9 years at 20 hours a week, or 1.0 years at 60. At $1.00/hr it halves to about 1,499 hours. Use the calculator on this page with the rate you were actually quoted; we don't publish rates because they move weekly.

How much does an RTX 3090 cost?

$1,499 at MSRP, which is a published specification rather than a live price. Street prices move constantly and we deliberately don't quote them. Check a retailer for what it costs today. What we can tell you is what the card actually does for that money: 37.95 tok/s on Qwen3 32B, and 8 of our 12 AI workloads running with 4 gated out.

Can an RTX 3090 run Llama 3.3 70B?

No. Llama 3.3 70B needs roughly 42GB at Q4_K_M and the RTX 3090 has 24GB. The weights don't fit, so it doesn't load at all. The biggest model in our LLM ladder it does run is Qwen3 32B at 37.95 tok/s. If a 70B is why you're buying, this isn't the card, and renting one for an hour would have told you that for the price of a coffee.

Can an RTX 3090 run FLUX.1-dev?

No. FLUX.1-dev needs roughly 26GB at BF16 and the RTX 3090 has 24GB. This catches people out constantly, because the card handles SDXL without complaint and feels like plenty right up until you try to load a modern image model.

Is the RTX 3090 worth buying in 2026?

Only if you'll saturate it. Owned hardware pays back on utilisation and nothing else, and our telemetry across the fleet consistently shows single-stream inference leaving these cards mostly idle. Token generation is bandwidth-bound, so the compute you paid for doesn't switch. If you'll run it hard and steadily, $1,499 amortises. If you're exploring, the break-even is years away and you'd be buying depreciation. There's also the harder limit: it can't run Llama 3.3 70B at all.

What does the break-even calculation leave out?

Deliberately quite a lot, and it moves in both directions. It ignores electricity and cooling, any PSU or case upgrade, the rest of the machine you'd need around the card, and resale value, which for a popular GPU can be substantial. It also ignores the value of not being locked to today's hardware for a multi-year break-even period. Treat the number as a floor for the buy case, not a full accounting.

So should I buy or rent this card?

My call on this specific card: BUY it if you can get it at a sane price. It was the no-brainer at ~$700 used; at today's ~$1,100 it's borderline, but 24GB in a gaming-capable card is still the best combo deal going. The bigger principle: you'd have to be running AI agents at a genuinely extreme, always-on level for owning to beat renting in 2026. Compute is being commoditized, what you can access in 2030 won't resemble today and should be much cheaper, so buying locks you into a depreciating slice of that curve while renting rides it.

How we test

Every speed and gate figure here is from our own benchmark runs. Cards marked Measured were rented by the hour and run by us on the GPU Battle AI Suite v2; Estimated cards are interpolated per workload against those anchors and labelled on every row. LLMs run on llama.cpp (llama-bench) at Q4_K_M with -p 512 -n 128. Diffusion and video run on diffusers/ComfyUI at BF16, SDXL at FP16. Warmup plus multiple timed runs each; we publish the mean. Run-to-run variance is under 0.5%. Telemetry is sampled at 1 Hz. Where a model exceeds a card's VRAM we publish a hard won't-fit with the requirement we observed, rather than dropping to a smaller quantisation to manufacture a number. A card that can't run a model scores zero on it. On money: MSRP is a published specification and we show it. We do not publish live retail prices or live rental rates: both move constantly, and a number hardcoded into an evergreen page is wrong within a quarter and misleads whoever reads it later. That is why the calculator asks you for the rate you were actually quoted instead of assuming one. The break-even maths is simple and yours to check: purchase price divided by hourly rate gives the hours of rental you'd have to buy before ownership wins. The calculator deliberately ignores electricity, cooling, a PSU upgrade, the rest of the machine, and resale value. Those move the answer in both directions and none of them are ours to estimate for you. All performance figures are single-GPU, single-stream, batch-size-1, what one card does for one user. Vendor and MLPerf numbers use large batches across many GPUs and will be far higher. Neither is wrong; they answer different questions.
