Intel Sandy Bridge to Introduce New Sockets, Chipsets, Reorganize Platform Further
Intel plans a pair of new sockets for launch with its new processor architecture that succeeds Westmere, codenamed "Sandy Bridge", which are due for 2011. As part of its "tick-tock" product launch strategy, the company is currently transitioning between the 45 nm "tock" (Nehalem architecture), and 32 nm "tick" (Westmere architecture). In 2011, it will transition from the 32 nm "tick" (Westmere architecture), to the 32 nm "tock" (Sandy Bridge architecture). The company uses a "tick-tock" model of process development, where each processor architecture gets to be made in two successive manufacturing processes, while each process gets to build two succeeding architectures. It seems to have become clear that with Sandy Bridge, Intel will also switch to new socket designs, making existing motherboards obsolete then. Architecturally, Sandy Bridge will introduce new feature-sets that make the CPU more powerful, clock-to-clock, such as AVX - Advanced Vector Extensions, an evolution of the SSE instruction set, native AES engine which has been introduced with Westmere, and so on.
The present LGA-1156 package on which Intel builds value-through-performance processors including a bulk of mainstream processors, will be succeeded with the LGA-1155 package. Though similar, LGA-1155 and LGA-1156 are not inter-compatible, meaning that LGA-1155 processors will not work on existing LGA-1156 motherboards, and LGA-1156 processors will not work on LGA-1155 motherboards, either. For these processors, the arrangement of vital components is similar to the LGA-1156 package, except that every LGA-1155 processor - dual-core or quad-core - will feature an on-die display controller.
