Original: Benchmark NVENC vs CPU transcoding (and find your real break-even) with FFmpeg

Short summary

Learn to measure GPU (NVENC) vs CPU transcoding cost-effectiveness using FFmpeg, VMAF quality metrics, and a cost-per-encoded-minute formula. GPU is cheaper only when saturated with parallel streams—use the provided benchmarking scripts to find your real break-even instead of trusting generic benchmarks. Covers preset tuning, quality measurement, parallel throughput testing, and rate-control modes.

  • •Quantify GPU vs CPU transcoding costs using a cost-per-encoded-minute formula
  • •VMAF quality metrics show software x264 edges NVENC by ~2-3 points at similar sizes
  • •GPU wins only at high parallelism (8+ streams); single-stream workloads favor CPU
