AMD Readies Dual-Core CPU

Advanced Micro Devices will release dual-core Opteron processors for servers and workstations in 2005, the same time frame that Intel plans for its first dual-core products, an AMD executive says.

The Direct Connect architecture used to build the Opteron processor makes it easy for AMD's designers to place two processor cores on the same silicon die, says Ben Williams, vice president of AMD's server and workstation business. Opteron features an integrated memory controller and Hypertransport interconnects that can connect the processor to the I/O port or directly to another processor, he says.

AMD will release more details about its dual-core processors as it approaches their release in 2005, Williams says.



Several chip makers are looking to dual-core designs as a way to increase the performance of next-generation processors without the constraints imposed by rising levels of power consumption in single-core processors. Two common methods of improving the performance of a single-core chip are increasing clock speed or adding cache memory, both of which require more power.

A dual-core chip is basically two separate processors on a single chip. Those two processors can outperform single-core processors on most multithreaded applications while running at lower clock speeds and consuming less power.

An application with multiple software threads will run faster on a dual-core processor because the operating system can assign an individual thread to its own processor core. Multithreaded applications running on a single-core processor must wait for one thread to finish before another thread can be processed.



IBM and Sun Microsystems have already released dual-core chips for high-end servers. The server world is especially primed to take advantage of multicore technology because so many applications for servers are already multithreaded, Williams said.

Earlier in May, Intel announced that it would shift all of its future server, desktop, and notebook processor development projects to dual-core designs. By 2005 Intel expects to have a dual-core chip available for each of those three segments, said Intel President and Chief Operating Officer Paul Otellini last week during the company's biannual financial analyst meeting in New York.

Williams was unable to comment on AMD's plans for dual-core PC processors. However, as more client applications become multithreaded, dual-core processors will make sense in all product lines, he says.

ATXA Main Board central quite empty

Standard ATXA structure box, right beside the power switch interface can be seen through a mini-Main Board on the Main Board received ATXA 256MB PC3200 memory, the following are covered by the heatsink to the CPU. . Minière can see the Main Board and the "Dragon Dream computer" on the Main Board are not the same.

ATXA Main Board central quite empty, and most are concentrated in mini circuits and components on the main board. These are photographs Godson desktop (Note : No photo model for the development of September 10, The models were displayed at the site the day of Jiangsu Ltd. Kelong dream of the "Dragon Dream computers." also known as the "Godson box" model, as common Godson processors on the 2nd. mix related chipsets designed to store and display flexibility Peripherals), Sina Tech SHLUG exclusive authorized release. SHLUG while more than three hours of live video are being processed.

MIPS similar structure

Although it is 95% compatible with the MIPS systems in order. Godson he would not mention the "MIPS similar structure." 16. Godson debut in the PC, Novell Suse Linux Desktop 10.1 done a 3D display Xgl hardware acceleration using the operating system, Linux system can truly realize the significance of 3D graphics effects. Sina Xgl integration technology in the last month have tried Suse Linux, with transparent objects, 3D effects and zooming function even more than WinXP and MacOS desktop graphics. Xgl framework made from the most beautiful, the circle of the most respected. Shanghai Linux User Group (SHLUG) in the Shanghai region is a focus on GNU and free / open source software community activities. its Linux community technology exchange has organized four.

Godson on the 2nd of the 64-bit processor

Godson MIPS64 not fully compatible with the instruction set, a number of additional multimedia instructions. Subsequently, the CPU Info Sunchunyang for everyone to see, is shown in the frequency of 439MHz processors. said actual frequency is 439MHz × 1.5. uname - MIPS64 is 2.4.22. According to him, after the framework Godson an independent named GodSun2, instead of MIPS64. MIPS RISC processor technology companies in the United States occupy an important position, MIPS Processor delegated many manufacturers, the distribution of a wide range of products. Godson last year accusing the company structure on the 2nd MIPS intellectual property violations. Godson on the 2nd of the 64-bit processor design to manufacturers of integrated circuits, Divine Godson Ltd. Chinese Academy of Sciences to calculate its design unit. Wei - Godson CPU chief designer said that China's own intellectual property rights is fully developed Godson on the 2nd.

AMD to be in the lead in progress

HT 3.0 support for Opteron 12XX and A64 models listed. First half of 2008, code-named Shanghai (Shanghai) will be published by the four core processors. Budapest 22XX and 82XX version of the form to the stage. Is designed to meet the Olympic Games? Why not for the code to Beijing? Intel at the end of 2006 will be issued against the four core processor for desktop and server market. AMD to be in the lead in progress. However, the latter's four core processor in the system will be fully up to date, there may be a very good performance.
