Haswell is the codename of a CPU (central processing unit) architecture developed by Intel, first announced to the public on June 4, 2013. They are part of the Intel series 8 and series 9 chipsets. The Haswell architecture uses the FinFET ("3D" or non-planar) transistor design with the 22 nanometer manufacturing process. The FinFET manufacturing process produces processors with both improved performance and increased power efficiency.
Haswell processors use the following types of sockets.
- LGA (land grid array) 1150 and LGA 2011-v3 for desktop machines.
- PGA for some mobile devices and laptops.
- BGA (ball grid array) for all-in-one PCs, Mini-ITX motherboards, tablets, and Ultrabook laptops.
