The code-named Bearlake-X chipset that will replace the Intel 975X from the top in the Q3 2007 will support PCI Express 2.0 bus with higher – 5.0GHz – clock-speed compared to current 2.5GHz, two PCI Express x16 lanes, dual-channel PC2-6400 (DDR2 800MHz) and PC3-10600 (DDR3 1333MHz) memory. Other members of the Bearlake family will also support central processing units (CPUs) with 1333MHz PSB, but they may not necessarily support multi-GPU capabilities as well as PC3-10600 (DDR3 1333MHz) memory, limiting maximum memory speed to PC3-8500 (DDR3 1066MHz),
The pictures also mention Core 2 Quad Q6600 as well as Core 2 Extreme QX6700 microprocessors with four processing engines. Nevertheless, the slides do not reflect Intel’s “second generation” quad-core CPUs that are due to become available in the second half of 2007.
