The "Sandy Bridge" processors we are seeing here today are Intel's second generation of "Core" processor that will be represented under the brand names of Intel Core i3, Core i5, and Core i7.
Sandy Bridge however represents mostly Intel's mainstream line of processors with the Sandy Bridge Core i7 moving somewhat into Intel's Performance processor lineup. The current LGA 1366/X58 platform will remain at the top of the stack throughout 2011.
Like the previous Westmere generation of processor, Sandy Bridge will too be a 32nm process part. It does however have a very new microarchitecture that builds on the previous Nehalem and Pentium 4 architectures. Big gains in Instruction Per Clock and energy efficiency will be obvious once you see our application benchmarks and power testing.
