2001-09-10 Intel 845 Chip set for Willamette first launched with SDRAM support. Includes the new ICH-3 hub featuring two ATA-100 ports and six USB 2.0 ports. DDR support added in Q1-02. Formerly known as Brookdale.
2002-01-07 Intel Pentium 4 2.2 Willamette core shrunk to 0.13 um starting at 2.2 GHz introduced at $562. Uses the 478 pin socket and the Tehama or Brookdale North Bridge. Includes 512 kB cache.
2002-05-06 Intel 850E High-end chip set for Northwood, previously known as Tehama-E, using the 533 MHz front side bus. Still uses the ICH2 south bridge with 4 USB 1.1 ports. PC1066 RDRAM is now (Oct -02) even offically supported...
2003-04-22 AMD Opteron AMD's 64 bit extension to IA-32 aka Sledgehammer or Hammer. 0.13 micron chip using "HyperTransport" for internal data traffic, a NUMA (Non-Uniform Memory Access) bus to speed up large multiprocessor systems. The version with 1 MB of L2 cache includes 100 million transistors on an area of around 180 mm2.
Starts at 1.8 GHz and consumes about 70W of power. Later, 1.8 and 2 GHz chips will be released, followed by 2.2 GHz, 2.4 and 2.6 GHz. Server prices are rumoured to start at $3000 to $6000.
Three types available: 8xx, for up to eight-way servers, 2xx for dual servers and 1xx for single processor systems. The xx is a subjective performance number.
In April, Opteron 240 ($283), 242 ($690), and 244 ($794) was launched.
On 03-06-30 the 840, 842, 844 ($749-$2149), 140, 142 and 144 ($229-669) were released.
On 03-09-09 the 146 and 846 were released.
