The Haswell architecture is specifically designed to optimize the power savings and performance benefits from the move to FinFet (non-planar, "3D") transistors on the improved 22 nm process node.
Haswell has been launched in three major forms:

1. Desktop version (LGA1150 socket): Haswell-DT
2. Mobile/Laptop version (PGA socket): Haswell-MB
3. BGA version:
   • 47 W and 57 W TDP classes: Haswell-H (For "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.)
   • 13.5 W and 15 W TDP classes (MCP): Haswell-ULT (For Intel's UltraBook platform.)
   • 10 W TDP class (SoC): Haswell-ULX (For tablets and certain UltraBook-class implementations.
     
     
     

     Performance

     Compared to Ivy Bridge:

     • Approximately 8% better vector processing performance.
     • Up to 6% faster single-threaded performance.
     • 6% faster multi-threaded performance.
     • Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.
     • A 6% increase in sequential CPU performance (eight execution ports per core versus six).
     • Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000.
     • Total performance improvement on average is about 3%^.
     • Wider Core: fourth ALU, third AGU, second branch prediction unit, deeper buffers, higher cache bandwidth, improved front-end.
     • ^[HNI, includes Advanced Vector Extensions 2 (AVX2), gather, BMI1+BMI2, LZCNT and FMA3 support).
     • The instruction decode queue, which holds instructions after they have been decoded, is no longer statically partitioned between the two threads that each core can service.
     • New sockets – LGA 1150 for desktops and rPGA947 & BGA1364.
     • New socket –LGA 2011-3 for the Enthusiast-Class Desktop Platform Haswell-E
     • Intel  Transactional Synchronization Extensions (TSX), on selected models.
     • Graphics support in hardware for Direct3D 11.1 and OpenGL 4.0
     • DDR4 for the enterprise/server variant (Haswell-EX)
     • DDR4 for the Enthusiast-Class Desktop Platform Haswell-E
     • Variable Base clock BClk
     • There are four versions of the integrated GPU: GT1, GT2, GT3 and GT3e, where GT3 version has 40 execution units (EUs). Haswell's predecessor, Ivy Bridge, has a maximum of 16 EUs. GT3e version with 40 EUs and on-package 128 MB of embedded DRAM (eDRAM), called Crystal Well, is available only in mobile H-SKUs and desktop (BGA-only) R-SKUs. Effectively, this eDRAM is a Level 4 cache — shared dynamically between the on-die GPU and CPU, and serving as a victim cache to the CPU's L3 cache.
