Best Cloud Rendering for V-Ray Architecture: GPU vs CPU Cost on Cloud
V-Ray for architecture supports both GPU and CPU rendering on cloud — and the cost difference is significant. V-Ray GPU on iRender (RTX 4090, ~$8.20/hr) renders a 4K arch-viz interior in roughly 8–15 minutes, costing about $1–2 per image. V-Ray CPU on GarageFarm or RebusFarm can finish similar scenes in 5–12 minutes, but per-image cost lands at $2–5. The short version: GPU is cheaper per image for most arch-viz. CPU is better if your scenes rely on features V-Ray GPU doesn’t fully support yet.
| Farm | V-Ray Mode | Model | 4K Interior (est.) | Cost/Image (est.) |
|---|---|---|---|---|
| iRender ⭐ | GPU (V-Ray GPU) | IaaS — RTX 4090 | ~8–15 min | ~$1–2 |
| GarageFarm | CPU (V-Ray) | SaaS — multi-node | ~5–12 min | ~$2–5 |
| RebusFarm | CPU (V-Ray) | SaaS — multi-node | ~5–15 min | ~$2–6 |
| Xesktop | GPU (V-Ray GPU) | IaaS — RTX 3080/4090 | ~10–18 min | ~$2–3 |
| AWS EC2 | Both | IaaS — self-managed | Varies | ~$12–20/hr |
When Should You Choose V-Ray GPU vs CPU for Architecture on Cloud?
V-Ray GPU on a cloud RTX 4090 is faster and cheaper per image for most standard arch-viz — interiors, exteriors, product shots. The 24 GB VRAM handles complex materials and high-poly furniture without issues. For batch renders of 20–50 angles on a residential project, GPU mode on iRender saves money vs CPU farms.
But V-Ray CPU still has its place. Certain features — volumetric fog, some procedural textures, specific light cache settings — only work reliably in CPU mode. If your workflow depends on these, a SaaS farm like GarageFarm gives you hundreds of CPU cores without server management. RebusFarm has a particularly smooth plugin workflow that some studios prefer.
What’s the Catch with V-Ray GPU Rendering on iRender?
iRender is IaaS — you get a remote desktop, install V-Ray yourself, and configure your scene. First-time setup: 15–30 minutes. Billing is hourly and doesn’t stop when your render finishes. Leave it running overnight and you’re out roughly ~$65.
Compare that to GarageFarm or RebusFarm: install a plugin, upload your scene, get results back. No server management, no billing timer anxiety. Per-image cost is higher, but the workflow is genuinely easier. For a solo architect doing occasional renders, that simplicity might be worth it.

Frequently Asked Questions
- Is V-Ray GPU or CPU cheaper for architecture rendering on cloud?
For most arch-viz, V-Ray GPU is cheaper per image. On iRender’s RTX 4090 (~$8.20/hr), a 4K interior costs $1–2. V-Ray CPU on GarageFarm or RebusFarm runs $2–6 per image. The gap widens on batch renders — 30 images on GPU: $30–60 total vs $60–150 on CPU farms.
2. Can I use GarageFarm or RebusFarm for V-Ray architecture rendering?
Yes — both are strong for V-Ray CPU rendering. GarageFarm offers hundreds of CPU cores with a simple plugin workflow. RebusFarm has one of the smoothest upload-and-render experiences available. Both handle V-Ray for 3ds Max, SketchUp, and Revit with zero server management.
3. What are the downsides of using iRender for V-Ray architecture?
iRender is IaaS — you manage the server yourself. Setup takes 15–30 minutes the first time. Billing runs hourly and doesn’t stop when rendering finishes — an idle overnight session wastes ~$65. No plugin integration like GarageFarm or RebusFarm. The upside: significantly cheaper per-image cost for GPU batch work.
