Intel H81 Chipset EOL'd: Long Lived Haswell Chipset to be Retired
 

Intel has announced that it will be discontinuing some of its Lynx Point based chipsets which are most commonly associated with its Haswell processors on socket LGA 1150. Along with the long-standing H81 chipset, other Intel Lynx-point chipsets entering the End-of-Life cycle include Q87, C226, QM87, and HM86.

Originally introduced to the market back in 2013, Intel's H81 chipset is the latest casualty of Intel's product discontinuance strategy. The H81 chipset along with others entering product discontinuance are all based on its 32 nm lithography. The H81 chipset was built for Intel 4th generation Haswell processors and acted as the budget-conscious version of the Z87 chipset, minus some of its premium features including overclocking support.
