Why Is There No Turbo Boost in My Intel i3 Processor?

The Intel Core i3 is one of the three divisions that comprise the Core I series, which is the current production cycle of semiconductor company Intel's flagship brand of consumer-oriented processors as of July 2011. Although the dual-core central processing unit division shares many of the technologies of the other two divisions, it lacks one in particular: Intel Turbo Boost.


Intel Turbo Boost is a technology that Intel introduced in 2008 for some of its consumer-oriented central processing units, which go on desktop and laptop personal computers. They're meant to increase the clock speed of the processor -- the rate at which it performs its basic functions -- in situations when the operating system demands optimal performance.


Intel introduced the Intel Turbo Boost technology in November 2008 on Nehalem-codenamed Intel Core i7 processors referred to as the i7-9xx. Within the next two years, Intel applied the Turbo Boost on the rest of the Core i7 chips, as well as the Core i5 entries, all of which consist of dual-, quad- and six-core processors. The second-generation version of the technology, Intel Turbo Boost 2.0, is applied on the second-generational Core i5 and i7 CPUs.


The Intel Core i3, debuting in 2010, is the youngest of the Core i-series CPUs as of 2011. It's also classified as the low-end entry. The Intel Core i5, which was introduced in 2009, serves as the Core brand's mid-range CPU. The top-of-the-line division is the Intel Core i7, which coincidentally came out in 2008, the same year as the clock speed-boosting technology. The Core i3's status as the budget-oriented version of an otherwise premier brand is the main reason why it doesn't have the Intel Turbo Boost.

Clock Speed Results

The Intel Core i3 has a peak clock speed of 3.33 GHz with the i3-560. The Intel Core i5 and the Intel Core i7 have their peak clock speeds with the 3.6-GHz i5-680 and the 3.4-GHz i7-2600, respectively, thus surpassing the i3. The Intel Turbo Boost only increases those speeds to 3.86 GHz and 3.8 GHz, respectively.
