ThinkCentre M90q Gen 5 vs Mac mini M2
Une lecture côte à côte pour tdp.
Comprendre tdp
TDP is a thermal design specification. Coolers and chassis are designed to dissipate the TDP figure indefinitely without throttling.
Why it's not power consumption
Modern CPUs and GPUs can briefly exceed TDP during boost (Intel's PL2, AMD's PPT, NVIDIA's power limit). They also dip below TDP at idle. The TDP figure is the sustained-load expectation, not a constant draw.
Why it matters
- Laptops. Lower-TDP chips fit in thinner chassis with longer battery; higher-TDP chips need beefier cooling.
- Mini PCs. A 65 W chip in a 0.8 L chassis will throttle. A 35 W chip will not.
- Desktops. Drives PSU sizing and case fan choice.
In comparisons
Two CPUs with the same TDP and similar specs will usually feel similar in real-world use. Big TDP gaps (35 W vs 125 W) reliably predict large performance gaps under sustained load.
Ce duelThinkCentre M90q Gen 5's 85W is roughly 325% more than Mac mini M2's 20W (a 65W gap). Lower is better here, so Mac mini M2 takes the lead in real use.
Qu'est-ce que tdp ?
Thermal Design Power — the maximum sustained heat output a CPU or GPU is designed to dissipate, measured in watts. A guide for cooler sizing, not an absolute power consumption number.
