The X38 And G35 Chipsets
Below we have a quick-take of Intel's 12 month chipset roadmap. Here we see where each variant is to be positioned in the desktop market, both mainstream and high-end.
Notable data-points on this slide are the future G35, X38 and Eaglelake family of chipsets. The X38 specifically will usher in PCI Express 2.0 serial technology with its bi-directional 5Gb/s SerDes (serializer/de-serializer) technology, essentially doubling available bandwidth over PCI Express 1.0a and 1.1 standards-based products. These 32 PCI Express 2.0 lanes, will also be backwards compatible, auto-negotiating down to PCI Express 1.1 data-rates as needed. When this chipset hits the market, it is bound to be potent. Beyond the X38, Eaglelake, slated for sometime in Q2'08, will bring forth Intel's ICH10 Southbridge and support for HD-DVD/Blu-Ray processing, among other enhancements.
Much like the dynamic duo of the P35 and G33, the X38 chipset will have an integrated graphics empowered counterpart, namely G35. G35 will mark Intel's first DX10 compliant graphics core, with full support for SM4.0 rendering. Note the emblazoned Windows Vista logo of course, which will be prominent branding we are sure, on the retail shelves and case badge artwork. The G35 will also have support for HDCP over what Intel calls "SDVO" or Intel's Serial Digital Video Out technology. SVDO is an Intel proprietary mechanism for transfering digital display CODEC functions over the PCI Express interface. The technology has actually been around since the 945G series chipset was introduced.
