Intel plans to launch its 2nd generation quad-core processors - the Yorkfield series–as replacement parts for the upcoming Core 2 Quad (codenamed Kentsfield) CPUs in the third quarter of 2007. Yorkfield will have one L2 cache shared directly by each pair of chips, enabling more efficient quad-core operation, with less FSB bandwidth. Yorkfield will be paired with the next-generation Bearlake chipset family, which will support a 1333MHz FSB and a PCI Express 2.0 interface. The first Yorkfield-based systems, which will utilize the Bearlake X chipset and DDR3-1333 memory, will target the high-end gaming market.
