Intel CPUs, such as the Core i7 adopted by VAIO, have "Intel® Turbo Boost Technology 2.0" installed, which enhances performance at peak usage. However, the period during which maximum performance can be maintained is limited by power consumption and temperature, and the performance will degrade. "VAIO TruePerformance" is technology designed to maintain higher performance for a longer period of time by increasing CPU power limits and more efficiently eliminating heat.
