To the Opteron 6100-series for servers more than twice as fast as its predecessor, with six cores. AMD promotes energy efficiency and low prices. Chips for four-processor systems, there is no extra cost.
AMD has introduced the new Opteron 6000 Series processor with eight or zwolf cores for server systems. The new series, code-named Magny-Cours is that AMD faster, cheaper and more energy efficient, as the competition’s products.
The new processors with the serial number 6100 - the first series of the 6000-series - are in floating-point up to 119 percent faster than their predecessors to work with six cores. The integer performance is supposedly higher by 88 percent. The clock frequencies of the series amount to 1.7 to 2.4 GHz. Various energy saving techniques such as C1E sleep state to minimize power consumption.
The 6100 processors are both two-CPU as well as for four-CPU systems thinking. According to AMD chips for four-processor systems should not be more expensive than those for systems with two CPUs. The cheapest 6100-processor is the AMD Opteron 6128, 2.0 GHz and eight cores for $ 266. The best Zwolfkernprozessoren, the Opteron 6164 HE (low-energy, 1.7 GHz) and Opteron 6168 (1.9 GHz), cost $ 744. For the performance-top model 6176 SE with twelve cores and 2.3 GHz AMD demanded $ 1386.
It is expected that servers offer manufacturers such as Hewlett-Packard, Dell, and Cray systems soon with AMD’s 6100-processor.
Just recently, Intel had introduced a chip with six cores. The top model of server Xeon 5680 costs $ 1663.
So far, mostly spread processors with two and four cores. Chips with six cores are found mainly in expensive high-end servers. The more cores a processor has, the faster it works in theory. However, the software threads can be distributed to multiple cores in order to use them effectively.
The test electrode assembly: acer aspire 5050 battery , acer aspire 5550 battery , acer aspire 5560 battery , acer aspire 5570 battery , acer aspire 5580 battery , acer aspire one battery , etc.
Preparation of working electrode: the line and conductive carbon graphite, PTFE mass ratio of 75 2 20:5 stick together, grinding in agate mortars in even tune into a paste, the paste evenly spread on the radius of a circular 0.4 cm collector (copper foil), the by 15 MPa at 130 °C after 5 min into the suppression of vacuum oven maintained at 120 °C for 24 ho namely the test electrode.
The test electrode into the glove box, glove box placed 2 PO Box solid powder to keep dry, with vacuum pump replacement glove box with hydrogen gas three times, and after standing in the ammonia filled 12h, to ensure that ammonia trace gas in water is PZOS absorbed as much as possible. Self-made two-electrode cell using simulation to test the electrochemical properties of the metal piece to hang on the electrode, the prepared electrode as working electrode, with Celgard 2300 as separator, electrolyte and solvent composition of methyl ester dimethyl carbonate (DMC ) B vinegar carbonate (EMC) ethylene vinegar (EC Pu I: I: I (W / W), the main electrolyte to I mol / L LiPF6. battery assembly 48 h after the balance later use.
Electrochemical experiments
Current charge and discharge experiments Roofer tester on the battery, all experiments were carried out at room temperature about 25 °C, all the experimental three-electrode system are carbon electrode as working electrode wire, metal file film as electrode and reference electrode . All experiments mentioned homogeneous electrode potential for Li / Li -ion.
AC impedance experiments 5208T woP haseL ock-inA nalyzer on with PARCM388 software control.
