The best selling point of the AMD’s Llano A8-3820 is its low price and the fact that it comes with a decent integrated graphics. We have started seeing a lot of desktops with the A8-3820 desktop processor. So if low cost desktop with decent entry level performance is your criteria, A8-3820 is a good processor.
The Intel’s Core i5-2400 is a better alternative in terms of performance. It is clocked higher, and, as you can see from the benchmarks, its CPU performance is significantly better that the AMD’s A8-3820. This is not something you will feel in daily computing, surfing etc., but, if you are compiling a lot of programs and doing really something that takes few seconds ( or few minutes) to execute, you will benefit in terms of efficiency by investing in Core i5-2400 ( or even better – core i5-2500K). If however, a better ( integrated) graphics is your main criteria and you do not need the external graphics card, the AMD’s A8-3820 will turn out to be a better choice.

Some more details of AMD A8-3820
The A8-3820 bumps up the speed of the A8-3800 before the Trinity chips arrive. With Turbo boost feature available, this should give slight bump to the performance but it is still not comparable to the best selling core i5 ( for example core i5-2500K) Sandy Bridge processors.
Some more details of Core i5-2400
The core i5-2400 is 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, mos 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.
