Techopedia explains Sandy Bridge
Sandy Bridge architecture based microprocessors consist of one or more cores that increase the performance of computing using hyperthreading (HT), where each core can be used separately for a specific computing function or process. The Sandy Bridge architecture is composed of 1-2 billion double-gate transistors per processor with a maximum of eight cores on board.
Sandy Bridge consists of processor models such as Core i3, Core i5, and Core i7. Each processor has a clock speed rate of 1.6 Ghz to 3.3 Ghz, L3 Cache, GPU speed of up to 1.3 Ghz and advanced video decoding and encoding features.
