Cheapest GPUs to rent — budget picks that still deliver
Budget GPUs on GPUniq rent from about $0.05/hr. The sweet spot is the RTX 3060 12GB: enough VRAM for Stable Diffusion, 7B-parameter LLMs in 4-bit, and most coursework, at rock-bottom prices. Pay a little more for an RTX 3090 (24GB) when model size — not speed — is what blocks you.

| # | GPU | VRAM | Min $/hr | Median $/hr | Available | Why this card |
|---|---|---|---|---|---|---|
| 1 | RTX 3060 | 12GB GDDR6 | $0.05 | $0.09 | 389 | 12GB for pocket change — Stable Diffusion, small LLMs, learning CUDA. |
| 2 | RTX 4060 | 8GB GDDR6 | $0.08 | $0.10 | 35 | Ada efficiency and DLSS-era drivers at entry-level prices; 8GB VRAM. |
| 3 | RTX 3060 Ti | 8GB GDDR6 | $0.07 | $0.13 | 64 | Noticeably faster than the 3060 when 8GB VRAM is enough. |
| 4 | GTX 1660 Super | 6GB GDDR6 | $0.08 | $0.08 | 15 | The absolute floor for CUDA experiments and classic ML. |
| 5 | RTX 3090 | 24GB GDDR6X | $0.15 | $0.22 | 1132 | The "budget 24GB" — when VRAM, not budget, is the real constraint. |

Frequently asked questions
What is the cheapest GPU I can rent for Stable Diffusion?
An RTX 3060 12GB comfortably runs SDXL and Flux-schnell inference. On GPUniq it rents from roughly $0.05–0.10/hr — see the live minimum price in the table above; it refreshes every 5 minutes.
Can I run an LLM on a budget GPU?
Yes — 7B models in 4-bit quantization fit in 6–8GB and run fine on an RTX 3060 or even a GTX 1660 Super. For 13B in 4-bit you want 12GB+ (RTX 3060 12GB), and for 24GB the cheapest ticket is an RTX 3090.
Why are these GPUs so cheap to rent?
GPUniq is a marketplace: thousands of consumer cards compete on price, and per-second billing means you pay only for actual compute. Older and mid-range models are abundant, which keeps their market price near the electricity floor.
