Spring has come and Intel thinks it's time to do a bit of cleaning before moving on, so the Santa Clara based company decided to retire eight mobile 32nm processors from its lineup to make room for new and improved models based on the Sandy Bridge architecture. This decision affects eight of the company's Arrandale processors that were launched a little more than a year ago and includes the Core i7-640UM, i7-640LM, i7-620UM, i7-620LM, i7-620M, i5-540M, i5-520UM and i5-520M. All these processors were built using the 32nm manufacturing process, used a dual-core design and their frequencies range between 1.2GHz and 2.66GHz. As mentioned earlier, these chips are based on the Arrendale architecture that is basically a 32nm die-shrink of Nehalem with integrated graphics and an integrated PCI Express controller. The chips will be replaced by processors based on Intel's current Sandy Bridge architecture. In addition to these CPUs, Intel also plans to retire the Celeron SU2300 processor which should be replaced by the upcoming Celeron B847 chip that is built using the Sandy Bridge architecture and packs integrated graphics. Just as Intel has done every time it has retired a product from its lineup, the chips will still be available for ordering a little more than six months from now and delivery is expected to end in April 2012. Ever since the year has started, Intel has announced that it will retire a large number of processors including the Core i7-980X Extreme Edition and almost all of its LGA 775 chips. This was done in order to make room for the company's new Sandy Bridge chips as well as for the upcoming high-performance LGA 2011 CPUs. Sometime during this quarter or early Q3, Intel will also add to its lineup a series of Pentium processors built on the Sandy Bridge core. (via ComputerBase)
