Fit the working scene
Textures, geometry, acceleration structures and renderer overhead all affect memory. Record the renderer and supported device configuration. A scene that fits on one device does not establish how another engine or scene will behave.
Plan the movement
Asset upload, shared storage and output download can change the turnaround time. Include software and licence costs when comparing a local farm with remote infrastructure. Data locality and rights to the assets also matter.
Measure a representative queue
Use a mix of difficult and ordinary frames. Count accepted frames, re-renders and artist iteration time. Compare total deadline risk and operating support alongside the per-hour compute cost.
Prepare a comparable test
Keep the workload, software version, data path, service objective and cost boundary attached to the result. Changing these assumptions changes what a comparison means.
