"VFX workstation" covers two genuinely different machines, and studios often spec the wrong one for the job: a render node that needs to sustain full GPU load for hours without throttling, and a grading/compositing station that needs a fast single-GPU pipeline, colour-accurate output and low-latency scrubbing through large timelines. Building one machine to do both usually means it's mediocre at each.
A render node in Blender, Octane, Redshift or V-Ray often runs unattended for hours. The number that matters isn't the GPU's rated boost clock — it's whether the machine holds that clock for the full duration. That comes down to case airflow, fan curve tuning and power delivery headroom, not just buying a faster card. A render node that throttles 20 minutes into an overnight job effectively becomes a slower, more expensive GPU.
DaVinci Resolve grading and compositing work is more sensitive to storage latency and RAM headroom than to GPU count — scrubbing a high-resolution timeline needs fast NVMe and enough system memory to hold caches without dropping to disk. A single strong GPU with a colour-accurate display pipeline typically serves a grading artist better than splitting a budget across multiple GPUs meant for rendering.
| Data | What it needs |
|---|---|
| Active project / timeline files being edited | Fast NVMe, low latency |
| Render output / cache | High-capacity storage, sequential speed matters more than latency |
| Delivered client masters | Backed up off the workstation, not just stored locally |
Mixing these roles onto one drive is a common cause of a workstation feeling slow under load even when the GPU is fast — the drive is doing two jobs with conflicting access patterns.
Studios buying multiple machines for a pipeline get better value speccing render nodes and grading stations differently rather than buying identical "do everything" boxes for both roles. A render farm of 3-4 nodes plus 1-2 grading stations, each spec'd for its actual job, usually costs about the same as uniform high-end boxes across the board — and performs better at both jobs.
ProStation Systems builds both kinds of machines to order — multi-GPU render nodes validated under 48-hour burn-in so they hold clocks for real production loads, and single-GPU grading workstations tuned for Resolve.
