Thermal Velocity Boost
Intel's opportunistic boost feature that gives the CPU a bit of extra clock frequency as long as it's kept below a certain temperature (often ~70 °C). It rewards good cooling directly: the cooler the CPU, the higher it holds the boost clock.
Mechanic: on top of regular Turbo Boost, TVB adds another few hundred MHz when the temperature is below the threshold; if the CPU crosses the temperature limit the extra steps are pulled back automatically. Win: cooling translates directly into performance without manual overclocking — a good cooler gives measurably higher sustained clock. Trade-off: under heavy, prolonged load (or poor cooling) the TVB gain quickly fades, so it shows most in shorter bursts and well-cooled systems. It illustrates the modern trend: CPUs overclock themselves dynamically based on temperature, current, and voltage instead of fixed multipliers. AMD's equivalent is Precision Boost.
