A higher end Clarkdale hyperthreaded dual core processor. Came with similar amount of cores as i3-540 but comes with performance boosting features such as turbo which boost operating frequency to determined clock. For most users might worth looking to spend $30 more for more powerful i5-750 which comes with 4 core and 4 thread. Still worth it for today albeit for light gaming and modern basic tasks.
