Intel Core 2 Quad Q9400
Released March, 2008
The Pros:Highly stable when overclocking, supports over 1 GHz of additional clock speed. Idles at very low temperatures, 25-30 degrees. Stock cooling is more than sufficient, even for some overclocking.
The Cons:Some detectable slowdown doing complex multi-tasking applications. Some other Intel chips (i5) with higher clock speeds can be found for lower or the same price.
The Intel Core 2 Quad Q9400 is a 45nm, ‘Yorkfield’ quad-core 2.66GHz microprocessor featuring a dual-die quad core design with two unified 6 MB L2 caches. Essentially a little brother to the Q9450, the Intel Core 2 Quad Q9400 runs on 45nm architecture with a 1333FSB and 6MB (versus 12MB) of L2 Cache.
