Intel plans on releasing Haswell architecture-based microprocessors, sometime in 2013, these chipsets will replace the existing Sandy Bridge lineup. The upcoming chipset plans have been leaked courtesy a chinese website. The new platform will be based on a new socket the LGA 1150 that will replace the existing LGA 1155 socket. Existing coolers will be compatible with the socket however the pin count will be different. The chipset will now handle only analog video signals, whereas the digital signals, like DisplayPort is moved to the CPU.
The chipset will support six USB 3.0 ports as well as power and performance optimizations for Rapid Storage Technology driver and vPro enhancements. The new design will cause less power consumption and hence less heat.
Intel has not confirmed any of these tidbits, so its safe to say that they can be had with a pick of salt and a late glass of soda to gulp it down, till the official announcement is made.
