Buy vs rent · measured first-party · Updated October 2026
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.

Watch: Is the RTX 3090 Still Worth It for AI in 2026?

$1,499 MSRP, 24GB, 350W. AI Score 7.7/100. Runs 8 of our 12 workloads, gated out of 4. Every figure measured on our own bench.
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.
Rent or buy the RTX 3090: your numbers
Renting the NVIDIA GeForce RTX 3090 on RunPod costs about $0.264/hr (the listed $0.220 plus 20% for idle time and storage); owning it costs about $0.053/hr in electricity at 350W and $0.15/kWh.
| If you paid | Hours until owning wins | At 4 h/day | At 8 h/day |
|---|---|---|---|
| $500 | 2,364 | 1.6 years | 0.8 years |
| $1,000 | 4,728 | 3.2 years | 1.6 years |
| $1,500 | 7,092 | 4.9 years | 2.4 years |
| $2,000 | 9,456 | 6.5 years | 3.2 years |
| $3,000 | 14,184 | 9.7 years | 4.9 years |
The interactive version takes your own price; launch MSRP is not used, since 2026 street prices sit far from it.
Break-even at a few illustrative rates, $1,499 RTX 3090
| If you're quoted | Hours before buying wins | Years at 20 hrs/week | Years at 60 hrs/week |
|---|---|---|---|
| $0.25/hr | 5,996 | 5.8 | 1.9 |
| $0.50/hr | 2,998 | 2.9 | 1.0 |
| $1.00/hr | 1,499 | 1.4 | 0.5 |
| $2.00/hr | 750 | 0.7 | 0.2 |
Purchase price ÷ hourly rate = hours of rental you'd buy before ownership pays. Use the calculator above with your actual quote. These rates are illustrative, not offers.
What you'd be buying, RTX 3090, measured, single stream
Q4_K_M on our bench. The largest model in our LLM ladder the RTX 3090 can hold is Qwen3 32B.
What I learned running three of them. I had a triple RTX 3090 rig, about $2,400 all in, as my entry-level AI setup. What I didn't plan for was power. Three 3090s are a literal heater in your house, and my energy bill went up 50% in one month. All the savings I thought I was making over renting mostly disappeared, and I sold them about a year ago.
Rental prices haven't helped the buy side either. The cheapest 3090 we track was about $0.07 an hour in August and is $0.22 now. Even at that higher rate, the $1,499 launch price buys 6,814 rented hours, which is 9 years at two hours a day of batch work.
RTX 3090 vs 4090 vs 5090, measured on our bench
| Model | Unit | RTX 3090 | RTX 4090 | RTX 5090 | 4090 vs 3090 |
|---|---|---|---|---|---|
| Qwen3 32B | tok/s | 37.95 | 44.28 | 71.15 | 1.17x |
| Qwen3 8B | tok/s | 137.59 | 164.32 | 243.91 | 1.19x |
| Stable Diffusion XL | images/min | 7.46 | 16.28 | 21.08 | 2.18x |
| Z-Image Turbo | images/min | 3.83 | 7.42 | 10.72 | 1.94x |
| LTX-Video (distilled) | frames/s | 2.17 | 4.7 | 10.45 | 2.17x |
| Stable Video Diffusion | clips/min | 1.06 | 2.23 | 2.84 | 2.10x |
Across all 21 language models we measured on all three cards, the 4090 is a median 1.19x the 3090 and the 5090 1.80x. Across 17 image and video models it's 2.01x and 2.75x.
Text vs image and video. For language models the 3090 still holds up: the 4090 is only about 19% faster on text across the 21 models we ran on both, because token generation leans on memory bandwidth and the two cards are close there. For image and video it's a different card: the 4090 is about 2.0x the 3090 and the 5090 about 2.8x, because the newer architectures do the diffusion math far faster.
So for chat and code, a subscription is usually the better deal, since they're subsidizing you. For image and video, the 3090 is the slow option at a premium price, and the models that don't fit in 24GB need a 48GB card you can rent by the hour. If you already own a 3090, hold on to it. If you don't, rent for batch jobs until prices come back to earth.
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.
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.
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.
