One of the primary tasks, which stood before Intel engineers with the development of sandy bridge design, there was to integrate graphic core in one crystal with the processor. For this reason graphic core was completely rebuild-ed and from the processor design side it is simply some more processor core. For connection and interaction of processor core, graphic core and caches is created the new internal bus ring, which works at the fixed frequency : 3 GHz.
Caches for each processor core now are called Last level cache (LLC). In Sandy bridge the cache of last level (LLC) works at a constant fixed frequency. In this case the latency with the work of cache are reduced and the second port for the data load is introduced.
Separately instructions and addresses go from data.
In Sandy bridge was realized a new generation of turbo boost technology, which ensures the acceleration of processor core or graphic core depending on the needs of usable applications. In this case it can overclock to the maximum immediately all processor core, including graphic, but not like the previous generation:
At peak load exceeding max TDP is allowed.
Approximately for 20-25 seconds system will be overclocked over the permissible limit.
Four core processor from default 3,4 GHz can reach in peak load 4,9 GHz. We do not forget also about the presence of hyper threading technology
