The new ‘turbo mode’ will bump up the processor’s frequency to as high as 1GHz as long as the temperature stays below 85°C. The patch would dynamically up the voltage and frequency of the core till the thermals hold. According to the Foundation, users have the option of choosing one of five peak frequencies; the highest being 1GHz. Users may go one step at a time and achieve higher frequencies as long as the board doesn’t start behaving abnormally.
The thing to note here is that all the parts of the Raspberry Pi will have different thermal characteristics meaning that one board may show higher turbo speeds compared to other. The increase in frequency is also dependent on quality of power supply to some extent.
Tests were carried out by the Foundation that show that the ‘turbo’ enabled board is "52 per cent faster on integer, 64 per cent faster on floating point and 55 per cent faster on memory."
Users can get this feature by downloading the new version of the Pi OS. The new OS not only includes the ‘turbo mode’ but, also includes other features like lowering of the USB interrupt rate; improvement in analogue audio quality; and some extra software.
