quad-core amd barcelona

Within the framework of measure international solid state circuits conference (ISSCC) took place the presentation, in the course of which AMD yesterday reported a certain new information relative to the native four core processor opteron under the code name barcelona.
Quad-Core AMD opteron, on the concept and expectations of company, must exceed to 40% competitive decisions (Intel xeon 5300 series), and its micro-architecture will improve the indices of heat emission and energy consumption. Among the improvements and technology AMD powerNow!, which is called dynamically to controle the frequency separately taken by the core of processor.

Direct connect architecture and built-in processor memory controller will allow the processor barcelona to decrease the supply voltage, even if controller works on the total power. The memory controller in this case can produce the independent variables from the core of servicing queries to the memory, reaching energy savings of . For achievement of even larger savings in the processor barcelona is used the technology of automatic swithing off of part from logic elements.

The futures Of quad-Core AMD opteron barcelona will preserve the thermal pack, utilized in processors AMD today: 68, 95 and 120 W.

Besides the allotment of attention to questions of reduction in energy consumption and increase in the energy-effectiveness, in processors quad-Core AMD opteron in the company AMD they thought also about the improvements in performance. Servers and desktop applications must prove to be in the gain from the used improvements core and the work of the cache in processor Barcelona. In particular, this concerns the Web- applications, which actively load cache. The discussion deals with Web servers, bases , mail servers, who will obtain serious addition in performance from the 2 mb of divided cache L3.

The tests, excuted in the laboratories AMD, showed 70% increase in performance (in comparison with todays dual core AMD opteron) in some applications of data bases also to 40% in applications, connected with the floating-point calculations. Some applications will also obtain addition in performance with the work on new processors because of the use technology AMD virtualization (AMD- V).

Appearance on the market for processors quad-Core AMD opteron barcelona is expected in the middle of this year (tentatively, at the end of second quarter). Arrival in the market For barcelona must help AMD to strengthen the positions of company on market 2P and 4P+ servers, and also powerful work stations and to slow down the drop in prices on it is 2 core opteron processors .
