Pentium E5800 Vs Core i3-2120

A lot of water has flowed under the bridge since the launch of the Wolfdale Pentium E5800 processor. Intel made a complete revamp in the processor architecture with the Arrandale that succeeded Wolfdale. It brought in an Integrated memory controller and an Integrated graphics Unit. The Sandy Bridge further improved upon the architecture by unifying the Graphics and the processor core in a single die besides improving the processor performance for a given clock.

The final result is that, the core i3- 2120 is way faster than the Pentium E5800 even when its clock frequency in only 100 MHz higher (3.30 GHz Vs 3.20 GHz). In addition, you get an integrated graphics and you don’t have to put in an extra graphics card ( provided you are not into cutting edge gaming).

The table below lists out the feature differences. We have also listed out some benchmarking comparison in the table below that.

Some more details of Pentium E5800

Intel’s Pentium E5800 is a dual core desktop processor with moderate performance. Some of its architectural shortcomings leads to inferior performance as compared to the Core i3 processors. It has proportionally better performance compared to E5700. The E5800 is priced competitively at $64 ( according to Intel).

Some more details of Core i3-2120

The Core i3-2120 is the second generation Intel Core i3 processor ( Also called Sandy Bridge Processor) improving significantly upon the architecture that evolved from Arrandale. Although turbo boost is not available in the core i3-2120 ( 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.
