Max core temperature (Tj max):
100 °C
Thermal stability:
74/100
How this metric is calculated
Σ(wᵢ × vᵢ) / Σwᵢ — adaptive renormalization
Почему 10-е поколение грелось сильнее 6-го при том же Tj=100°C: больше ядер при том же TDP → выше thermal density. Tj max слабо дифференцирует (324 CPU на 100°C), поэтому 4-факторный композит.
Factors and weights:
weight 0.3
CPU Tj max
= 100 °C
weight 0.4
CPU ядер/ватт
= 0.2143 ядер/Вт
weight 0.2
CPU современность техпроцесса
= 0.25 1/нм
weight 0.1
CPU обратный TDP
= 0.035714 1/Вт
Adaptive renormalization: weights of missing factors are excluded from the denominator.
Tech modernity:
90/100
How this metric is calculated
Σ(wᵢ × vᵢ) / Σwᵢ — adaptive renormalization
0.4×percentile(normalized_score) + 0.4×percentile(energy_efficiency) + 0.2×percentile(1/tech_process_nm). Унифицированный аналог tech_modernity_index для processors.
Factors and weights:
