Intel 915P/915G and 925x Chipsets

Intel has just launched its Grantsdale and Alderwood chipsets series for Pentium 4 processors to succeed the current generation 865/875 series. For Intel, the mainstream 915P/915G (Grantsdale) and performance targeted 925x (Alderwood) series chipsets mark many new significant technology conversions.

The new chipsets offer support for DDR2 memory and include support for advanced SATA RAID, Intel's High-Definition Audio technology, PCI-Express, and PCI-Express Graphics (x16)  PCI-Express x16 sets the standard for video performance with dedicated read/write bandwidth, allowing 4GB/sec bandwidth one way and 8GB/sec bandwidth in bidirectional mode. All chipsets are optimized for Pentium 4 Hyperthreading technology and in the future some will support a faster 1066 FSB speed (not yet available). The Intel 915G series will feature integrated graphics (known as Graphics Media Accelerator 900).

With so many new technologies packed into these chipsets it offers a great platform for future growth, higher performance, and acceptance of new standards. Time to upgrade again!
