Intel plans to launch two new entry level chipsets in Q3 this year to replace the current 946GZ/PL and 945G chipsets. Intel G31 Express and P31 Express support the current Intel Core 2 Duo and Core 2 Quad processors as well as the upcoming 45nm Yorkfield and Wolfdale. Both chipsets support 1066FSB and 1333FSB subsequently in Q1'08 upon validation, DDR2-800 memories up to 4GB and allow one x16 PCIe slot for discrete graphics. However, the new chipsets are paired with the older ICH7 southbridge. The Intel G31 Express also comes with integrated Intel GMA 3100 graphics like G33, Q33 and Q35 chipsets.
