Intel Readies New Memory Controller for Nehalem Chips

By

Intels code-named Nehalem processors have been discussed for nearly five years now, but Intel was tight-lipped enough in order not to disclose details of the new micro-architecture itself as well as implementation peculiarities. Nevertheless, recently Intel started to inform its partners about the future platforms, which means that at least some peculiarities of the new chips have come to light.

Three memory channels supporting PC3-12800 (DDR3 1600MHz) memory would provide approximately 38.4GB/s memory bandwidth, up significantly from about 21.3GB/s memory bandwidth available today. Given that in 2009 Intel plans to release Nehalem processor with built-in graphics core, triple-channel memory controller may help to keep performance in 3D games on relatively high level.
