If you thought that nothing interesting is going to happen on Socket 775 scene after Core i7 was promoted, we can only tell you that you have made a wrong assumption. Core 2 Duo and Core 2 Quad CPUs are still very fast and, to be quite honest, enough for most today tasks. Intel decided to continue with optimizations of Core 2 Quad models and results are presented in form of model Q9400s that we got in our test lab. Intel Core 2 Quad Q9400s is direct descendant of C2Q Q9400 model. Probably you have noticed that only difference is in letter "s" at the end of marking. That suffix means that this is CPU with lower power consumption or smaller TDP (Thermal Design Power).
