Yorkfield is the code name for some Intel processors sold as Core 2 Quad and Xeon. In Intel's cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23, replacing Kentsfield, the previous model.
Like its predecessor, Yorkfield multi-chip modules come in two sizes. The smaller version is equipped with 6MB L2 cache, and is commonly called Yorkfield-6M. The larger version is equipped with 12 MB L2 cache.
The mobile version of Yorkfield is Penryn-QC and the dual-socket server version is Harpertown. The MP server Dunnington chip is a more distant relative based on a different chip but using the same 45 nm Core microarchitecture. The Wolfdale desktop processor is a dual-core version of Yorkfield.
The successor to Yorkfield is Nehalem based Lynnfield.
Yorkfield (codename for the Core 2 Quad Q9x5x series and Xeon X33x0 series) features a dual-die quad core design with two unified 6 MB L2 caches; their product code is 80569. They also feature 1333 MT/s FSB and are compatible with the Bearlake chipset. These processors were released in late March 2008 beginning with the Q9300 and Q9450. Yorkfield CPUs were expected to be released in January 2008. The release of Yorkfield, however, was delayed to March 15, 2008. Initially this delay was attributed to an error found in the Yorkfield chip, but later reports claimed that the delay was necessary in order to ensure compatibility with the 4-layer printed circuit boards utilized by many mainstream motherboards. At the Intel Developer Forum 2007, a Yorkfield processor was compared with a Kentsfield processor.
