As of 2015, the Intel Core i7-3770K and the Intel Core i5-4570 are both fast processors designed for desktop computers. The Intel Core i7 processor is designed with high-end computing in mind, while the i5 is a more accessible middle class variant with a lower price point.
The i5 and i7 series of processors are largely similar to each other, but the variances that Intel introduces between each model equates to faster speeds and quicker computations. For example, the base frequency of the i5-4570 processor is 3.2 gigahertz, while the i7-3770K manages to increase that speed to 3.5 gigahertz. What this means is that when under a heavy strain, a computer can operate faster if it has a higher processor base frequency because the transistors inside can open and react that much quicker.
The maximum turbo frequency also marks a difference between the two processors. The i5-4570 manages 3.6 gigahertz, while the i7-3770K pulls ahead with a 3.9. This means that when a computer initiates Intel’s Turbo Boost Technology and pushes the processor to run above its base operating frequency, both processors run even faster. However, the i7 still retains the most power.
The Core series of processors by Intel was first introduced in the form of the Intel Core i7 Bloomfield in November 2008. The first i5 processor, the Lynnfield Core i5, was later unveiled in September 2009.
