Intel announced last week that it had begun production of its next generation of microprocessors (code named Haswell) in the last quarter of 2012. The new hardware comes with 22nm technology that will bring lower power consumption and increased performance that make them an idea candidate for notebooks, desktop systems and especially Ultrabooks.
This is the 4th generation of the Intel Core i product range and one that should offer some big changes in the way we use our computers, most notably due to the massively reduced power consumption that should allow for all-day battery life, the biggest improvement in battery life in Intel's history. Intel have already said they expect this to make as bigger or bigger a splash than Centrino did years ago, I personally expect this to be a huge product for Intel and can't wait to get my hands on the next generation of Ultrabooks and desktops that feature the new range of CPU's.
Expect to see these new processors on the market mid 2013.
