The new server processor architecture-based AMD Bulldozer

server CPU. Interlagos with the number of nuclei from 12 to 16, which will be released in 2011.

AMD introduced some details of the processor architecture of the new generation, under the project name Bulldozer. The architecture will be the basis for the upcoming production of high-power 16-core server processor.

' Processors, based on this architecture will have more cores and run 50% faster than the chips in existing architectures ' - said Dina McKinney, vice president of AMD's processor architecture design. Increased productivity is achieved through greater flexibility in the distribution of computational tasks across multiple cores of the processor.

Bulldozer CPU architecture will be installed in different computers - from servers to laptops. The first chip is based on the new architecture will be the server processor, code-named Interlagos, having from 12 to 16 cores. He is scheduled for release next year.

Until now, the main developers of processors, Intel and AMD, achieved better performance by adding more cores, increasing the clock frequency, or by improving the ability to handle multiple streams of commands (threading) while. Innovation Bulldozer architecture will be an opportunity to increase productivity by combining execution cores in a pair (pairing) and the joint use of components of the CPU.

The increase in speed is achieved by separating the functions of individual components, such as a device floating -point between the two cores, which makes it possible to perform more operations per clock cycle.

Dedicated core are mainly used for common tasks, while the shared components - only if necessary. If processors have fewer components, they can be made smaller in size, and due to the greater efficiency of energy consumption is reduced.

According to test results AMD, processors based on the Bulldozer architecture are 50% more performance than AMD is now produced by 12-core CPU family Opteron Magny Cours.

' Earlier in the development of processor designers put at the heart of the performance as such, but times are changing ', - said Jim McGregor, chief research firm In-Stat.

Now the development of processors taking into account the requirements of new computer architectures aimed at applications such as databases or Web services, said McGregor. Applications have different hardware requirements, for example high performance with floating point calculations and high speed data exchange with memory.

The new processors will allow AMD to expand the range of proposals for the server market and successfully compete with Intel, which dominates in this segment.

' How successful is opposed to AMD Intel? .

In the second quarter, the share accounted for 93.5% of the Intel processor market for servers, while the share of AMD - only 6.5 %.

However, many manufacturers. servers. acknowledge that they are impressed by the cooperation with AMD, so the new processors will find supporters, says McGregor.

Now the family of servers based on Opteron processors produce such. server giants like Dell. , IBM and Hewlett-Packard.
