Which GPU is cost-effective for 3D rendering?

Blender / C4D / Octane rendering: Multi-GPU vs. single-GPU cost efficiency — Data updated: 2026-10-26

⚡ Direct answer: The lowest-priced option for 3D rendering is RTX 3090, minimum ¥0.63/hour(Vast.ai (USA)); Estimated total cost for rendering a batch for a medium-sized project (12 hours) ¥8Prices update hourly; refer to the order page for final pricing.

Recommended models and live prices (sorted by current lowest price)

GPU model	VRAM	Current Lowest Price	Platform	Per day	Rendering a batch for a medium-scale project (12 hours)
RTX 3090 Entry-level training powerhouse: SD image generation, LoRA fine-tuning, 7B–13B inference.	24GB	¥0.63/hour	Vast.ai (USA) Spot	¥15	¥8	Price comparison →
RTX 4090 All-rounder workhorse: Flux image generation, QLoRA fine-tuning of 13B models, video generation.	24GB	¥0.87/hour	Vast.ai (USA) Spot	¥21	¥10	Price comparison →
A6000 48GB Large 48 GB VRAM: 70B quantized inference, QLoRA fine-tuning of 70B models, rendering	48GB	¥2.38/hour	RunPod (USA) Spot	¥57	¥29	Price comparison →
L40S 48GB 48 GB VRAM sweet-spot GPU: ideal for 70B quantized inference and batch inference	48GB	¥5.69/hour	RunPod (USA) Spot	¥137	¥68	Price comparison →

Cost = current lowest hourly rate × duration. This is an estimate of compute rental only — storage, bandwidth and image fees are excluded, and spot prices change at any time. For long runs, compare monthly plans.

How to choose

Rendering scales with CUDA cores and VRAM; a single 4090 usually beats pro cards at the same price
When large scenes overflow VRAM, move up to A6000 48GB / L40S 48GB
Animation is billed by frame — render one frame to measure timing, then estimate the total

FAQ

How much does it cost to rent a GPU for 3D rendering?

On demand it runs a few to around ten-plus yuan per hour; this page shows a 12-hour project total based on the current lowest price.

Do I need multiple GPUs for rendering?

Multi-GPU gains are limited for a single frame; only frame-parallel animation really scales. Check whether your renderer supports multiple GPUs first.
