AMD Launches Opteron Quad-Core Server Processor
The release of the quad-core AMD Opteron quad-core line, previously known under the code name Barcelona, has finally taken place. The manufacturer, extolling the merits of the new chip, notes that it is “the most advanced x86 processor ever created and produced, and the first true quad-core x86 microprocessor”. The fact is that the new Opteron is truly a quad core (and does not consist of two dual cores in the same package) and features an efficient architecture, built using some innovative energy saving solutions.
The two main advantages of the new chip are energy-saving technologies and improved support for virtualization. As for the first, excellent results were achieved by using AMD CoolCore Technology (reducing power consumption by turning off unused parts of the processor), Independent Dynamic Core Technology (changing the clock frequency of each core depending on specific application performance requirements) and Dual Dynamic Power Management (DDPM), which provides independent power to the cores and the memory controller.
The power consumption of AMD's new processors is measured according to Average CPU Power (ACP), an indicator that gives an idea of the total power consumption of the processor, including the cores, the integrated memory controller and the HyperTransport lines, under a load that corresponds to the typical application set. AMD Opteron Quad-Core processors have ACP values of 55 and 75 watts. Nevertheless, AMD continues to specify the TDP (thermal design power) values in the processor specifications.
The second key advantage, improved support for virtualization, is realized through the Direct Connect Architecture architecture and the Rapid Virtualization Indexing function, which work at the hardware level. Previously, the functionality implemented by Rapid Virtualization Indexing was implemented at the software level. Transferring them to the hardware of the platform allowed us to drastically increase the speed of work.

As for performance, the new processors are 50% superior to their dual-core predecessors, the AMD Opteron Dual-Core processors. These data were obtained by comparing the results of the SPECint_rate2006 and SPECfp_rate2006 tests for the Dual-Core AMD Opteron Model 2222 and the Quad-Core AMD Opteron Model 2350. You can see the test results here .
The Quad-Core AMD Opteron line consists of nine processors. All models have the same cache sizes: L1 - 64/64 Kb (commands / data), L2 - 512 Kb per core, L3 - 2 Mb. Processors support SSE, SSE2, SSE3, SSE4 command set extensions. The integrated memory controller has a 128-bit data bus, supports ECC and Advanced ECC, and is designed to work with buffered DDR2-667 memory. The maximum number of DDR2 modules is eight (in this case, the maximum frequency is limited to 533 MHz).
The cost of chips, the first of which will be on sale already this month, will be determined in the region from $ 316 for the 1.9-GHz model 2347 and $ 873 for the 8347 HE model with the same clock frequency, but with reduced power consumption and designed to work in eight-processor servers.
