2004-05-10 Intel Dothan 90 nm successor to Banias, and the Centrino / Pentium M line, which will have a 400 MHz bus (533 in 05-Q1) and 2MB of cache. Will be called 735, 745 and 755 for 1.7 to 2.0 GHz processors costing $294, $423 and $637.
Slower (715 and 725) versions launch in Q3, and faster (760, 770: 533 MHz bus, up to 2.13 GHz) in Q4. Consumes 21W in performance mode. Earlier meant to launch in 03-Q3.
2004-06-21 DDR-II Memory technology borrowing both from DDR and RDRAM for improved thoughput. Uses smaller stubs, progammable impedance, etc to accomplish transferring 4 words per clock cycle. First used by GeForce FX (in proprietary version). Will show up in PCs in 2004-Q2, in for example Grantsdale, Via PT890 and ALi M1685.
2004-06-21 Intel ICH6 South bridge including four PCI Express x1 ports, and eight USB 2.0 ports. The ICH6-R (+$3) will support four S-ATA ports, while the normal ICH6 only includes two. There will also be ICH6-W (+$5) and -RW (+$7) versions with wireless capabilities and a ICH6-M for Mobile systems. Uses the new DMI (Direct Media Interface) to connect to the North Bridges.
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:
- 1bit, x1: 250 MB/s (312 MB/s raw), 8 pins. PCI replacement
- 4bit, x4: 1 GB/s, 20 pins
- 8bit, x8: 2 GB/s, 40 pins
- 12bit, x12: ? pins
- 16bit, x16: 4 GB/s, 80 pins. Replacement for AGP and connects to the North Bridge
- 32bit, x32: ? pins
"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.
2004 ExpressCard New expansion module standard replacing PCMCIA, developed by the PCMCIA organization. Communications based on PCI-Express and USB 2.0. Will be available in two sizes, the smaller 34x75 mm, and the larger 54 x 75 mm. Previously known as 3GIO-M or NewCard.
2005-01-19 Intel Alviso Chipset in Napa platform based on Grantsdale, but for notebooks succeeding Montara and Odem from the Centrino line. Likely to be available in several versions with (-GM) and without graphics. Earlier planned for 04-H2. G-version said to include the GMA900 graphics core.
Alviso is part of the Sonoma generation of the Centrino platform.
Napa64 is likely to be a Alviso with support for Merom.
