Most of the Bridge architecture processor uses locked and designed to enhance performance, which can not through the conventional overclocking. But the processor architecture also joined the Turbo technology-the Turbo Boost is used to boost CPU performance and more scientific management. Mentioned Turbo, I believe a lot of players and friends first impression is the application of turbo technology in the car. Turbo Boost technology and turbo can break through the performance of the CPU limit. Turbo Boost technology uses the means to adjust the CPU frequency to improve its performance. In dealing with complex applications, the processor can automatically increase the frequency to speed, depending on the application needs to maximize performance. In the case of high load, the processor frequency can be frequency raised to the default frequency of 110%. Turbo Boost technology, the essence is: the premise does not exceed the maximum TDP, try to tap the potential of the CPU.
Boost technology based on system load, the processor core intelligent management. Occupy two CPU cores in the Windows system default, the Turbo Boost technology will be the remaining two core shut down, in order to achieve the role of energy-efficient. Game high load applications, the technology depending on the application to decide whether to open the closed core.
Turbo Boost technology of intelligence is not only to automatically enhance the frequency and the core, also has a separate core frequency characteristics. For example, a program only needs to occupy a core, then the technology will be only one core overclocking, the other core is to maintain the usual state. This technique has obvious advantages for CPU energy-saving and efficient, and theoretically have a negative impact on performance is not.
The test used the game Kirin Core i5 3450 processor through SP 2004 software will be a core loaded with its rise to the highest frequency. Ivy Bridge processors support a separate Core Turbo mode, I set in the BIOS settings for all core running at the same frequency. Test software using frequency-sensitive Super PI test, were tested in the open energy-saving mode, and rose to the highest frequency processor performance to prove is there a performance gap.
