tdp nedir?

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.

Bu eşleşmeRadeon RX 9070 XT's 304W is roughly 16% more than Radeon RX 7800 XT's 263W (a 41W gap). Lower is better here, so Radeon RX 7800 XT takes the lead in real use.

Sözlük

tdp nedir?

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.
