Intel tapes out high-end desktop chipset for Nehalem core

Posted by Wolfgang Gruener

Chicago (IL) – Industry sources confirmed to TG Daily that Intel has received first silicon of its "Tylersburg" chipset, which will be available for high-end desktop processors built on Intel's new Nehalem architecture due in 2008.

Tylersburg HEDT ("high-end desktop") is a 65 nm chipset that is likely to follow Intel's "Logan" and "Bigby" single- and dual-socket 3-series chipsets (formerly code-named "Bearlake"). The chipset, scheduled for a H2 2008 release for desktop Nehalem processors will be released side-by-side with Thurley, a chipset for DP servers and workstations as well as "Foxhollow", which will be offered for UP servers and workstations.

Information on Tylersburg are scarce at this time, but we hear that the "AO rev" case out after one and a half years of development and exceeded internal expectations in terms of performance and power consumption. Apparently, the chipset will drop power consumption by 2X when compared to its direct predecessor – using features such as packet detect during low power states as well as low-power state support from third party PCI Express (PCIe) vendors and Intel's own PCIe devices.

Among the key additional features of Tylersburg are added PCIe lanes; sources did not indicate how many lanes there will be available in the end, but we know that it will be more than the six PCIe slots offered by the upcoming Bigby (which apparently will be a foundation for "Skulltrail", Intel's high-end enthusiast desktop platform for two quad-core processors.

Our sources indicated that Intel is closely watching AMD's release of the Barcelona processor and is somewhat cautiously optimistic on how its current Clovertown processor will compete with the CPU. The company believes that its upcoming 45 nm Core 2 Duo product line will keep a "broad leadership" position in the industry, Intel told employees that Barcelona "may challenge us on specific server/workstation benchmarks."

Intel aims to regain "clear performance and energy-efficiency leadership" with Nehalem in 2008. The company believes that the architecture will "provide the performance leading energy-efficient CPU cores" to stay ahead in the desktop and mobile segment in 2009.

Following Tylersburg, Thurley and Capella, Intel will be moving Nehalem processors into the "Capella" mobile platform, "Piketon" business desktops and "Kingscreek" consumer desktops in 2009.
