Scoring Methodology
Overall Score (0-100)
Each CPU receives a composite score from 0-100 based on three weighted factors. Higher scores indicate better QuickSync hardware encoding performance.
Performance
Percentile rank of average FPS across all benchmark tests. Measures raw encoding speed — how quickly the GPU can transcode video.
Efficiency
Percentile rank of FPS per watt consumed during encoding. Rewards CPUs that achieve high performance without excessive power draw.
Codec Support
Percentage of available test types completed. CPUs with broader codec support (H.264, HEVC 8-bit, HEVC 10-bit, etc.) score higher.
Score Calculation
The final score is calculated as:
Score = (Performance × 0.40) + (Efficiency × 0.35) + (Codec Support × 0.25) All sub-scores are normalized to 0-100 using percentile ranking against the entire database. This means scores are relative — as more CPUs are added, rankings may shift.
Data Sources
Benchmark results come from community submissions running the quicksync-benchmark.sh script. Results include FPS, encoding speed, and power consumption (where available) across standardized test files and codec configurations.
