Intel recently launched its high-end 3 series chipset X38 in the market, however with details of a chip revision, the X48 chipset, exposed, some motherboard makers are concerned that the X48 may hurt demand for motherboards based on the X38 chipset. Intel recently delivered X48 A0 test samples to motherboard makers. The chipset is expected to launch between the end of 2007 and January 2008 after testing, while motherboards should start appear on the market in the first quarter of 2008. With the X48's launch expected to come only three months later than X38, it could lead to a short life cycle for the X38, causing a delay in market demand.
