Instructions & virtualization

For Docker/AI/ML scenarios.

AVX AES-NI VT-x
Max core temperature (Tj max): 69 °C
Thermal stability: 6/100
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 = 69 °C
weight 0.4
CPU ядер/ватт = 0.0308 ядер/Вт
weight 0.2
CPU современность техпроцесса = 0.03125 1/нм
weight 0.1
CPU обратный TDP = 0.015385 1/Вт

Adaptive renormalization: weights of missing factors are excluded from the denominator.

Tech modernity: 7/100
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:
weight 0.4
CPU normalized_score = 2.16
weight 0.4
CPU энергоэффективность = 0.54
weight 0.2
CPU современность техпроцесса = 0.03125 1/нм

Adaptive renormalization: weights of missing factors are excluded from the denominator.
