Best Cloud Rendering for Corona Architecture: CPU Farm vs IaaS Comparison
For Corona architecture rendering, a traditional SaaS CPU farm is usually the better choice over IaaS. Corona is a CPU-only renderer — it doesn’t use GPU acceleration at all. That means SaaS farms like GarageFarm and RebusFarm, which distribute your scene across hundreds of CPU cores automatically, are a natural fit. A 4K arch-viz interior that takes 45–90 minutes locally can finish in 5–15 minutes on a multi-node CPU farm, at roughly $2–6 per image. IaaS farms like iRender (~$8.20/hr) work too — but you’re limited to the CPU cores on a single server, which makes them slower for pure Corona production renders. Where iRender does shine: Corona Interactive rendering, which requires a live 3ds Max session.
| Farm | Model | Corona Support | 4K Interior (est.) | Cost/Image (est.) |
|---|---|---|---|---|
| GarageFarm ⭐ | SaaS — multi-node CPU | ✅ Full (plugin) | ~5–12 min | ~$2–5 |
| RebusFarm | SaaS — multi-node CPU | ✅ Full (plugin) | ~5–15 min | ~$3–6 |
| Fox Renderfarm | SaaS — multi-node CPU | ✅ Supported | ~6–18 min | ~$2–5 |
| iRender | IaaS — single server | ✅ Manual setup | ~20–45 min | ~$3–6 |
| AWS EC2 | IaaS — self-managed | ✅ Manual setup | Varies | ~$12–20/hr |
Why Do CPU Farms Beat IaaS for Corona Production Renders?
It comes down to parallelization. Corona splits each image into “buckets” rendered across all available CPU cores. On GarageFarm, your scene gets distributed across dozens to hundreds of cores — a 4K image that takes 60 minutes on a 16-core workstation finishes in about 8 minutes on 120 cores.
On iRender, you’re limited to one server’s CPU (AMD Threadripper Pro, 256 GB RAM). For batch production of 20–50 images, a SaaS farm is almost always faster and cheaper per image.
When Does iRender Actually Make Sense for Corona Users?
Corona Interactive rendering. If you use Corona IR to preview lighting in real-time inside 3ds Max, you need a live desktop session — only IaaS farms provide this. GarageFarm and RebusFarm are batch-only. On iRender, you open 3ds Max, iterate in Corona IR, then hit final render — all in one session.
The catch: iRender’s billing runs hourly whether you’re rendering or tweaking materials. A 3-hour session costs ~$25. Forget to disconnect overnight — roughly ~$65 wasted.

Frequently Asked Questions
- Is Corona Renderer GPU or CPU based?
Corona is CPU-only — it doesn’t use GPU acceleration for final rendering. Render speed scales with CPU core count, not your graphics card. SaaS farms like GarageFarm and RebusFarm, which distribute across hundreds of cores, are naturally better for Corona than single-server IaaS farms.
2. Can I use iRender for Corona architecture rendering?
Yes, but it’s not ideal for batch production. iRender provides a single server (Threadripper Pro, 256 GB RAM) — powerful, but limited to one machine’s cores. Where iRender shines for Corona: interactive rendering with Corona IR in 3ds Max, which requires a live desktop session that SaaS farms can’t provide.
3. How much does Corona architecture rendering cost on a cloud farm?
On GarageFarm (SaaS), a 4K arch-viz interior costs about $2–5 per image. RebusFarm runs $3–6. On iRender (IaaS, ~$8.20/hr), a single 4K image costs $3–6 depending on render time on the server’s CPU.
