Throttling

Technology that allows the CPU to slow down if thermal output reaches a critical level or to improve power performance.

The Explain card

Plain English: Throttling is a hardware mechanism that deliberately slows a CPU (or GPU) when it gets too hot or when the system wants to save power. Less speed, less heat, less risk of damage.
Example: A GPU cluster serving a large language model hits its thermal ceiling during a spike in inference traffic. The chips reduce their clock speed, latency climbs, and requests time out, though nothing was attacked in the usual sense.
Why it matters: Throttling is a silent availability limiter. Attackers who trigger sustained heavy compute, through long prompts or adversarial inputs, can degrade service without ever breaching it. Watch thermal and clock metrics too.
Hook: The chip's own fever response: slow down before you burn out.

In a sentence

When the CPU package on the inference node crossed the thermal trip point, firmware began throttling and request latency on the model endpoint rose.

How it is built

Where it came from

Origin: English gerund of throttle, from Middle English throtele, probably a diminutive of throte (throat), from Old English throte, plus the native -ing suffix
Entered the language: c. 1400
What changed: The noun named a throat. The verb named the squeeze that closed one. Nineteenth-century engine rooms hung the same word on a valve that choked steam or fuel. Aviation of the 1930s said throttle back for cutting power. Computing kept the choke picture for a processor clock or a network link that is held down on purpose.

How it is spelled

Pattern: A silent e drops before a vowel suffix: throttle becomes throttling, never throttleing
Pattern: th spells /θ/ at the start of a syllable, as in throat
Pattern: Double t after a short vowel, as in bottle and settle
Breaks the pattern: Middle English wrote throtele and throtle before the modern double-t form settled
Breaks the pattern: the related body-part noun is throat, with oa and a single t, not thrott
