 Intel released a new Itanium 2 family member , codenamed Madison , in 2003 . Madison used a 130 nm process and was the basis of all new Itanium processors until Montecito was released in June 2006 .

 In 2006 , Intel delivered Montecito ( marketed as the Itanium 2 9000 series ) , a dual @-@ core processor that roughly doubled performance and decreased energy consumption by about 20 percent .

 Intel released the Itanium 2 9100 series , codenamed Montvale , in November 2007 . In May 2009 , the schedule for Tukwila , its follow @-@ on , was revised again , with release to OEMs planned for the first quarter of 2010 .

 The Itanium processors show a progression in capability . Merced was a proof of concept . McKinley dramatically improved the memory hierarchy and allowed Itanium to become reasonably competitive . Madison , with the shift to a 130 nm process , allowed for enough cache space to overcome the major performance bottlenecks . Montecito , with a 90 nm process , allowed for a dual @-@ core implementation and a major improvement in performance per watt . Montvale added three new features : core @-@ level lockstep , demand @-@ based switching and front @-@ side bus frequency of up to 667 MHz .

 The Fastra II was determined to be over three times faster than the Fastra I , which in turn was slightly faster than a 512 @-@ core cluster . However , because of the number of GPUs in the computer , the system initially suffered from several issues , like the system refusing to reboot and overheating due to a lack of space between the video cards .
