Sometimes, parallelized code can run slower than its sequential version because Intel Turbo Boost Technology can make the latter run at faster clock frequencies than the former. Therefore, if you work with a microprocessor with Intel Turbo Boost Technology enabled, you will have to pay attention to the changes introduced by this technology.

The easiest way to understand the changes introduced by microprocessors with Intel Turbo Boost Technology is working with a very simple code snippet as an example of the situation that could happen in more complex applications.
