Core i5-480M Vs Core i5-2540M Comparison, difference, benchmark
Core i5-480M Vs Core i5-2540M by Starred Reviews
The second generation core i5 Sandy Bridge Core processors have outsmarted the 1st generation Nehalem and Clarkdale processors.
Though the improvement is evolutionary rather than revolutionary, it is significant. Intel has merged the two dies into a single 32 nm Fabrication process. The performance of the integrated graphics has seen a significant improvement. The newer Turbo 2.0 further improves the performance, increasing Intel’s lead over AMD.

Some more details of Core i5-2540M
The core i5-25400M is a relatively fast processor belonging to the 2nd generation Intel Core i5 processor. The most characteristic improvement as compared to the 1st generation Intel Sandy Bridge processors is in the area of Integrated graphics powered by the Intel HD Graphics 3000 core. Integrated graphics is a part of the silicon and not a separate discrete component or a card. The Integrated graphics and the processor cores are all in one die unlike the earlier 1st generation processors, in which the processor and the integrated graphics were on separate die. The base frequency of the graphics runs at 650 MHz that can extend to 1.20 GHz depending upon the demand. The new Turbo boost 2.0 in the core i5-2520M significantly improves the performance of the processor. Communication with the chipset is using fast differential DMI Bus.
