More information on the Intel Lakeport chipset

Posted on Friday, September 19 2003 @ 15:34:22 CEST by

X-bit Labs reports some news about the successor of the Intel Grantsdale chipset. The Grantsdale will be announced in the Q2 of 2004, and the Lakeport will be coming in 2005. The Grantsdale will have a lot of new features and technologies like PCI Express, DDR-II Ram, a Socket T (LGA775), and probably motherboards based on it will be the first BTX motherboards.

The Lakeport chipset will come a year later than the Grantsdale, and will bring some speed improvements.

Traditionally, there will be, at least, two versions of the Lakeport: the Lakeport-G and Lakeport-P with and without integrated graphics core respectively. Both will support LGA775 processors with 800, 1066 or even 1333MHz Quad Pumped Bus as well as DDR-II memory at up to 667MHz clock-speed. Dual-channel PC2-5300 (DDR-II 667MHz) should provide enough bandwidth for CPUs with 1333MHz Quad Pumped Bus, hence, we can suggest that such microprocessors will emerge in 2005.

Surely, Lakeport chipsets will support code-named 90nm Tejas processors with 2MB L2 and some architectural improvements over the Prescott processors, but in case Tejas chips utilizing 65nm fabrication will emerge sometime in late 2005, the chipset should probably support them as well.

One of the very bright features provided by the Lakeport chipsets will be support for FB-DIMM memory modules. The FB-DIMM stands for Fully Buffered DIMM and represents a new approach of making memory modules. Such kind of DDR-II SDRAM devices will have a special hub-buffer onboard that will act as a concentrator for data and commands. This will allow increasing the number of memory modules supported by one channel in addition to overall improvement of peak memory bandwidth. Starting from 667 and 800MHz memory this buffer will be a compulsory part for DIMMs.

As for Lakeport’s integrated graphics core will support Pixel and Vertex Shaders 2.0, but there is also a slight possibility that Intel will integrate Shaders version 3.0 support as well.
