Tukwila is the code-name for the generation of Intel's Itanium processor family following Itanium 2 and Montecito. It was released on 8 February 2010 as the Itanium 9300 Series. While its features have not been publicly disclosed in detail, it utilizes both multiple processor cores (multi-core) and SMT techniques. The engineers said to be working on this project are from the Alpha project, specifically those who worked on the Alpha 21464 (EV8), which was focused on SMT. Named for the city of Tukwila, Washington,〔(【引用サイトリンク】 title=Intel changes code name of future Itanium )〕 Tukwila was previously code-named ''Tanglewood''. However the name coincides with the Tanglewood music festival, and Intel renamed the project in late 2003. The processor has two to four cores per die and up to 24 MB L3 of on-die cache. They are the first batch of processors to contain more than 2 billion transistors on a single die.〔(【引用サイトリンク】 title=Chips pass two billion milestone )〕 This total is made up as follows:〔(Intel shows off Tukwila, first 2 billion transistor CPU )〕 * core logic — 430 million. * system interface — 157 million * L3 cache — 1,420 million * I/O logic — 39 million * chip total — 2.046 billion Die size is 21.5×32.5 mm or 698.75 mm². ==Xeon compatibility== It has been publicly disclosed that Tukwila and its associated chipset would bring socket compatibility between Intel's Xeon and Itanium processors, by introducing a new interconnect called Intel QuickPath Interconnect (QuickPath, previously known as Common System Interface or CSI). This ultimate endeavor would help reduce product development costs for both Intel and its partners, by allowing for greater reuse of components and manufacturing processes.〔(【引用サイトリンク】 title=Intel Changes CPU Road Map )〕 Tukwila is reported to have four "full" QuickPath links and two "half" links.〔(【引用サイトリンク】 title=Intel’s Tukwila Confirmed to be Quad Core )〕 Whitefield, the first Xeon processor to feature QuickPath, suffered significant project delays and was cancelled.〔(【引用サイトリンク】 title=Intel's CSI to outperform AMD's Hypertransport )〕 Currently, the first Xeon MP processor to feature QuickPath is Beckton. The released Itanium 9300-series processors are using a separate socket, LGA 1248, which is incompatible with Xeon processors and motherboards. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tukwila (processor)」の詳細全文を読む スポンサード リンク
