Sandy Bridge E - Line-Up

At launch Intel presents three new Sandy Bridge E CPUs. There is a Core i7-3960X, a Core i7-3930K and a Core i7-3820. The first is the extreme model which comes with 15 Megabyte of shared L3-Cache and an open multiplyer. The K-Model ships with twelve Megabyte of cache and also an open multiplyer. The Core i7-3820 will ship with 10 Megabyte of shared L3-Cache and no open multiplyer. Within most line-ups that have been launched in the past years, Intel did vary with the clock speeds but not with the cache size. It is new that they equip CPUs with more L3-Cache in order to make them slower or faster.

Intels Sandy Bridge E CPUs also ship with a fantastic transistor count of 2.27 billion and they need almost one Billion as L3-Cache. Because Intels communicates the same amount of transistors for every CPU we were thinking if they produce all the news chips in one production line and simply deactivate parts of the L3-Cache on the 3930K and 3820.
