Score = average of 6 normalized CPU+GPU benchmark scores (CB R23 ×2, GB6 ×2, FireStrike, Time Spy; each normalized to dataset max = 100). Eff. = Score ÷ Watts × 10. HB = HandBrake encode time (s). Idle W = power at desktop idle. Idle/Load/Perf dB = fan noise at idle, load (default), and load (performance) profiles, measured at 30 cm. All ↓ columns: lower is better. Noise and power metrics are not included in Score.
