Core i3-2100 Vs Core i5-2500K Comparison

Core i3-2100 Vs  Core i5-2500K Comparison , by starred reviews

The core i5-2500K is clocked 200 MHz higher than the Core i3-2100, but, this is not the real charm of the core i5-2500K. The suffix K in the core i5-2500K indicates that it is an overclockable part. If you use a decent cooling, it is very easy to shoot the clock speed in the core i5-2500K from its nominal 3.3 GHz clock frequency to the over 4.0 GHz and beyond.

The next important aspect is the turbo boost. While the core i5-2500K supports turbo boost, the core i3-2100 does not has any.  The base clock frequency of Core i5-2500K is 3.3 GHz while its turbo frequency is 3.7 GHz ( of course when single core is active). Now if you overclock the base clock to 4 GHz, the turbo frequency rises to 4.48 Now that further increases the lead of the core i5-2500K over Core i3-2100.

As you increase the clock frequency, you also add the chance the the processor may shut down in the middle of of something. This is fine if you are not doing something mission critical. But if you wish to have a stable system, you may like to test the system for an overnight under a stress test.

Some more details of Core i3-2100

The Core i3-2100 is the second generation Intel Core i3 processor imroving significantly upon the architecture that evolved from Arrandale. Although turbo boost is not available in the core i3-2100 ( The newer turbo 2.0 technology, that increases the time for which processor can be in the boosted state, is available only on the second generation core i5 and i7 processors), the processor still shows significant performance improvement over similarly clocked 1st generation core i3 processor. The more significant improvement has been in the area of integrated graphics unit.

Some more details of Core i5-2500K

The core i5-2500K is the overclockable version of the core i5-2500. It belongs to the second generation Core i5 processor, more popularly known as the Sandy bridge Processor. There have been several improvement over the previous generation core i5 processor, most notable among them is the improvement in the integrated graphics ( x2 performance improvement). The new Turbo 2.0 further boosts the performance. In the lithography improvement the we now have a unified 32 nm die having everything on a single die. The higher passmark score of core i5-2500K with respect to the core i5-2500 only indicates that more samples sent the overclocked 2500K scores
