How much electricity does rendering a Blender animation use?

Energy used in kWh equals the computer's power draw in watts, divided by 1000, multiplied by the total render hours. A 400 watt PC rendering for 8 hours uses 3.2 kWh. At a rate of 0.15 per kWh that is about 0.48 in electricity.

Does Eevee or Cycles render faster in Blender?

Eevee is much faster, often rendering frames in under a few seconds because it is a real-time rasteriser. Cycles is a path tracer that produces physically accurate light and materials but takes far longer per frame, from tens of seconds to many minutes depending on samples and scene complexity.

How can I speed up Cycles render times?

Enable the denoiser and lower your sample count, turn on Adaptive Sampling with a noise threshold around 0.01, render on GPU rather than CPU, reduce light bounces, disable caustics if you do not need them, and turn on Persistent Data for animations so static geometry is not re-synced every frame.

Step by Step

How to Get Your Time Per Frame

The whole estimate depends on one number: how long a single frame takes at your final settings. Here is how to get it accurately.

1Set your final resolution, sample count, and render engine. A test at 50% resolution or half the samples will badly underestimate the real job.
2Pick a frame that represents the heaviest part of your shot, not the simplest. Motion blur, more objects on screen, and volumetrics all push render time up.
3Render it with F12. When it finishes, the time is shown in the header of the render window and in the image title bar.
4For a safer number, render a second, busier frame and average the two. Animation render time is rarely uniform across a shot.
5Turn on Render Properties → Performance → Persistent Data before the real job. It skips re-syncing static geometry every frame and can cut animation render time noticeably.

Ballpark Reference

Typical Render Times Per Frame

Rough time per frame at 1080p on a modern dedicated GPU. Use these only to sanity-check your own test render, not as inputs.

Scene type	Engine	Rough time / frame	Notes
Simple stylised shot	Eevee	0.5 – 3 s	Few lights, no heavy shadows
Complex scene, many lights	Eevee	3 – 15 s	Soft shadows, SSR, bloom
Product or character shot	Cycles (GPU)	30 – 120 s	Denoised, ~128 samples
Interior / archviz	Cycles (GPU)	2 – 10 min	Bounced light, glass, many textures
Volumetrics or caustics	Cycles (GPU)	10 – 60 min	Fog, fire, water, high samples
Any of the above	Cycles (CPU only)	3 – 10× slower	Depends on core count vs GPU

Hardware changes these numbers by an order of magnitude. A laptop iGPU and a workstation with two high-end cards can differ by 20 times or more on the same frame. Always run your own test render.

Cut the Time Down

Ways to Render Faster

Before committing to a long job or paying for a farm, most scenes have easy time to claw back.

1Denoise and drop samples. With the OptiX or OpenImageDenoise denoiser on, many scenes look clean at 64 to 128 samples instead of 512 or more.
2Adaptive Sampling with a noise threshold around 0.01 lets Blender stop early on easy pixels and spend time only where it is needed.
3Render on GPU, not CPU. On NVIDIA cards, choose OptiX in Preferences → System. It is usually the single biggest speedup.
4Lower light bounces. Diffuse 2 to 3, glossy 2, transmission 4 is enough for most shots. Disable caustics unless the scene needs them.
5Use the Simplify panel to cap subdivision levels and particle counts at render time for background detail nobody will inspect frame by frame.
6Consider Eevee for stylised or motion-heavy work. Eevee Next has closed much of the quality gap and renders many times faster.
7Use a render farm for deadlines. SheepIt is a free community farm that works on a credit system. Commercial farms parallelise across hundreds of nodes, so wall-clock time drops from days to minutes.

Common Questions

Render Time: Quick Answers

How long does it take to render a Blender animation?

Total render time equals frames × time per frame. A 10 second clip at 24 fps is 240 frames. At 2 minutes per frame that is 480 minutes, or 8 hours on one machine. Two machines in parallel halves it to 4 hours.

How do I find my render time per frame?

Render one representative frame at final settings with F12. The time is shown in the header of the render window and in the image title bar when it finishes. Average two frames of different complexity for a safer estimate.

How much electricity does rendering use?

Energy in kWh is watts ÷ 1000 × total render hours. A 400 watt PC rendering 8 hours uses 3.2 kWh. At 0.15 per kWh that is about 0.48 in electricity for the whole job.

Is a render farm worth it?

Yes when a job would tie up your machine for many hours or days, when a deadline is close, or when you need your computer free to keep working. Farms render hundreds of frames at once, so a 20 hour local job can finish in under an hour. For short jobs on a flexible timeline, local rendering is cheaper.

Does Eevee or Cycles render faster?

Eevee is far faster, often under a few seconds per frame, because it rasterises in real time. Cycles path traces for physically accurate light and takes tens of seconds to many minutes per frame depending on samples and scene complexity.

Can I use my computer while it renders?

Yes, but it slows the render because the GPU and CPU are shared. For long jobs, render from the command line or use background rendering so the viewport is not also drawing, and avoid other GPU-heavy apps.

How do I speed up Cycles renders?

Turn on the denoiser and lower samples, enable Adaptive Sampling at a noise threshold near 0.01, render on GPU with OptiX, reduce light bounces, disable caustics, and switch on Persistent Data for animations.
