Introduction & Specifications
It was not too long ago that the web was buzzing with dual-core versus quad-core debates. Sides were taken and lines were drawn. At that time, one of the main arguments against quad-core processors was their high asking price. But as time passed and manufacturing refinements were made, costs steadily decreased and quad-cores found their way into the more mainstream market segments. And before you knew it, a price war was imminent.
Intel and AMD have been going at one another for years. With AMD unable to compete well at the ultra high-end of the market, however, their focus shifted towards the mainstream market segments. As always, Intel responded and their most recent salvo comes in the form the affordable Core 2 Quad Q8400 processor. Since the Q9400, a 2.66GHz Yorkfield quad-core, was already on the market, why did Intel feel the need to release another, affordable quad-core model? One reason could be to increase yield and utilize dies that would otherwise be discarded. Another reason would be to position another product at the same price point as AMD's. Whatever the case may be, competition is always good for the consumer as it usually drives prices lower and provides more options to choose from. With that in mind, let's take a look at the Intel Core 2 Quad 8400 to see if it's worthy of consideration for your next build...

45nm Yorkfield Quad-Core
There isn't a shortage of options for those on the market for a 45nm Intel quad-core CPU. From the 3.2GHz Extreme Edition QX9770 to the 2.33GHz Q8200, Intel has the entire price spectrum covered. Those looking for a low power option can also choose from the S-series processors, which sport lower 65W TDPs. Where exactly does the Q8400 fit in to the mix? Let's find out...
