Intel core i3-2100 Vs Core i5-2400 comparison and difference

The Intel core i5-2400 is a quad core processor while the core i3-2100 is a dual core processor. But this is not the only reason core i5-2400 is faster than core i3-2100. The presence of the turbo boost, and higher L3 Cache ( Intel Smart Cache) leads to significant performance improvement in core i5-2400 with respect to core i3-2100 even when both of them are clocked same at 3.1 GHz .

The table below captures the feature as well as performance difference between core i5-2400 and core i3-2100

Table : Intel core i3-2100 Vs Core i5-2400

SL. No.
Core i3-2100 Core i5-2400
Clock Frequency 3.1 GHz 3.1 GHz
Number of Cores 2 4
Passmark Score 3817 6100
Turbo Boost None 3.4 GHz
Price $117 $184
Number of (Hyper) Threads 4 4
TDP Rating 65 Watts 95 Watts
Smart Cache ( L3 Cache) 3 MB 6 MB

As is evident from the Passmark score the core i5-2400 is  significantly faster than the core i3-2100 in the performance.

The only question is whether the   higher price of core i5-2400 ( at $184, according to the Intel ) is justified. The price of the i5-2400 is 1.57 times the price of i3-2100. If we rely upon the performance scores from Passmark, the performance of i5-2400 is 1.59  times that of the core i3-2100.

The two processors have therefore be comparatively priced. You need to decide if you need the processing power offered by the core i5-2400. The core i3-2100 is still fast by any standard for most of your home and office computing needs.
