- Physical factors
- PC cooling is very complex and PCBS 2’s simulation uses a simplified model.
- The silicon lottery in real life can, on rare occasions, be very large. In PCBS 2 we use a smaller differential in order to avoid creating game-breaking job objectives.
- Software factors
- PCBS 2 uses manufacturer-stated clock speeds to run components in a default (non-overclocked) situation. Drivers are now becoming very sophisticated in auto-overclocking components to give users improved performance. PCBS 2 does not simulate this.
- PCBS 2 will always give the same benchmark score for the exact same PC in game. In real life, scores can differ each time on the same PC owing to many factors.
- Mathematical factors
- PCBS 2 uses a statistical model based on thousands of benchmark runs. While this is great for broad accuracy, it doesn’t represent any single PC configuration, and so can never be 100% accurate.
