Sandy Bridge-E is the codename of an eight-core Intel processor based on the Sandy Bridge microarchitecture. It follows the six-core Gulftown/Westmere-EP processor that used the older LGA 1366 package, which is replaced with LGA 2011 starting with Sandy Bridge-EP. The CPUID extended model number is 45 (2Dh) and four product codes are used, 80619 for the UP Core i7 models and the higher numbers for the various Xeon E5 DP server models. In some models, only four or six of the physically present eight cores are enabled.
