DigiTimes
reports that Intel will officially start delivering its X38 chipsets in
mid-September, enabling motherboard makers to begin volume production of
X38-based motherboards by the end of this month, according to sources at the
makers. The official launch of the X38 chipsets will also come in time to
compete with AMD's forthcoming RD790 chipsets scheduled in November. In addition to supporting 1333MHz FSB, DDR3-1333 memory, PCI Express 2.0 (PCIe) and dual PCIe x16 graphics slots, the X38 will also be the first core logic chipset using ISH (integrated heat spreader) technology, the sources noted.
While barely beginning shipments of the X38, however, Intel also plans to launch
an upgrade version of the chipset, the X48, by the end of the year with
motherboard makers to begin delivering X48 motherboards to shelves in the first
quarter of 2008, according to sources close to Intel's roadmap. The X48
eventually will come with the same chip design as the X38 but will support
1600MHz FSB and DDR3-1600 memory, the sources stated. Board makers will not be
required to change any design work of X38-based motherboards since the X38 and
X48 chipsets will use the same PCB (printed circuit board), said the sources,
noting that the X38 could also support 1600MHz FSB and DDR3-1600 memory after
overclocking.
