AMD A8-3820 Vs Core i5-2500K

- The AMD’s A8-3820 is clocked slower than the Core i5-2500K and its CPU performance is slower than the Intel’s Core i5-2500K.

- The A8-3820′s integrated graphics (Radeon HD 6550D)  is however, significantly better than the Intel’s HD Graphics 3000.

- The A8-3820 is cheaper and has started appearing in newer desktops  ( as we write this on Feb 9, 2011). The Core i5-2500K is the Intel’s best seller processor for $229.

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 i5-2500K

The core i5-2500K is the overclockable version of the core i5-2500. It belongs to 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, most 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. The higher passmark score of core i5-2500K with respect to the core i5-2500 only indicates that more samples sent the overclocked 2500K scores
