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.
2004-03-11 Intel Yamhill The Intel 64-bit technology is called Intel Extended Memory 64 Technology (EM64T), 'CT' or IA32e and was previewed at IDF 2004.
Project was said to have been called *T ("star-T"?). IA32e is said to be largely compatible with AMD64, which is probably connected to the rumour that Microsoft is quoted as saying that they "will not support more than one 64-bit extension to the x86 platform" or something similar.
Will be launched for Nocona and Prescott LGA775.
2004-06-11 IBM Power5 Successor to Power4 built in 0.13 um technology. The MCM (Multi Chip Module) includes 4 chips with two MultiThreaded cores each presenting a total of 16 virtual cores on the MCM. Each chip also has a 36 MB L3 cache attached for a total of 144 MB of L3 cache on the MCM. Each MCM can be connected to other MCMs through a 4GB/s bus for up to 128-way multiprocessing.
A single core version, also with Simultaneous MultiThreading, may also be launched. Each core includes 120 registers (80 on the Power4) and is said to have 40% to 100% better performance. Will later move to 90 nm with the Power5+ version.
Will be available 2004-06-11.
