The best reason why you would prefer the AMD’s A6-3670K APU over the Intel’s Core i3-2100 is that it has a much better integrated graphics in the form of Radeon HD 6530D. The Core i3-2100 comes with HD Graphics 2000 ( not the HD Graphics 3000).
In CPU performance that two are about equal, with Core i3-2100 scoring better in lightly threaded applications. In cases where all 4 cores of the A6-3670K can be utilized, the AMD’s A6-3670K catches up the i3-2100 performance.

Some more details of AMD A6-3670K
The A6-3670K is the overclockable quad core Llano processor. It provides more value than the Core i3 Sandy Bridge processor by being cheaper and by having a better integrated graphics.
Some more details of Core i3-2100
The Core i3-2100 is the second generation Intel Core i3 processor improving 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.
