2004-06-21 Intel Prescott LGA775 Prescott using the LGA775 socket is launched. 64-bits (EM64T, CT Technology) for the desktop is slated for 05-Q2. EM64T chips will be called 'F' after the clock speed.

2004-06-21 Intel Alderwood 925X High-end chipset, succeeding Canterwood for Prescott and Tejas, while Grantsdale handles the "mid-end". ECC support was present, but has been removed from roadmaps. Priced at $50.
A faster version called i925XE with 1066 MHz will be launched in Q3/Q4.

2004-06-21 Intel Grantsdale 910/915 Desktop chipset for Prescott and Tejas (the Socket T or LGA775 processors). Supports DDR-II SDRAM (400/533) and the ICH6 south bridge. Graphics is enhanced with DX9 and DVI support, dual displays, faster graphics access etc and is called "Graphics Media Accelerator 900" (or GMA900), formerly known as "Intel Extreme Graphics 3". Will be launched as

2004-06-21 PCI Express PC interconnect formerly known as 3GIO. Evolved from PCI and the physical interface of InfiniBand to a serial high bandwidth interface which will be used both as a PCI / AGP replacement and for chip to chip communications. Runs at 2.5 GHz and 0.8 V today, but will move to 5 GHz in PCI Express 2 in 2007-2008, and later to 10 GHz. Provides independent channels for each direction. Multiple bus widths are available:

From PCISIG:
"PCI Express currently runs at 2.5Gtps, or 250MBps per lane in each direction, providing a total bandwidth of 16GBps in a 32-lane configuration. Future frequency increases will scale up total bandwidth to the limits of copper and significantly beyond that via other media without impacting any layers above the Physical Layer in the protocol stack."

Will also spawn a successor to the PCMCIA (PC-Card, CardBus) slot, 3GIO-M, Newcard or ExpressCard, which includes both PCI Express and USB 2.0 interfaces.
