Ivy Bridge: successor to Sandy Bridge, using 22 nm process, released in April 2012. Haswell 22 nm microarchitecture, released June 3, 2013. Added a number of new instructions, including AVX2 and FMA. Broadwell: 14 nm derivative of the Haswell microarchitecture, released in September 2014. Three-cycle FMUL latency, 64 entry scheduler.
Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture). [1]
Sandy Bridge is the codename for Intel's 32 nm microarchitecture used in the second generation of the Intel Core processors (Core i7, i5, i3). The Sandy Bridge microarchitecture is the successor to Nehalem and Westmere microarchitecture .

NOTE : This reference number 4 is on X79, which is a Sandy bridge -E, not Sandy Bridge, and PCIe 3.0 only is enabled when an Ivy Bridge-E CPU or Xeon E-5 series is used. 4 For Haswell enthusiast desktop platform. Haswell CPUs will provide up to 40 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes.
The chipsets contain a 'memory controller hub' and an 'I/O controller hub', which tend to be called 'north bridge' and 'south bridge' respectively. The memory controller hub connects to the processors, memory, high-speed I/O such as PCI Express, and to the I/O controller hub by a proprietary link.
Sandy Bridge-EP branded as Xeon E5 models aimed at high-end servers and workstations. It supported motherboards equipped with up to 4 sockets. It supported motherboards equipped with up to 4 sockets. Sandy Bridge-EN ( LGA 1356 ) uses a smaller socket for low-end and dual-processor servers on certain Xeon E5 and Pentium branded models.
