Sapphire Presents New Graphics Card HD 7870 Flex with Dual-X Cooler

Sapphire Technology has officially presented a new model of its graphics card with the implemented unique Flex solution. Codenamed HD 7870 Flex Edition, this card is based on Graphics Core Next architecture developed by AMD. One of the peculiarities observed in this model is the integration of a high-end cooling system Dual-X that is called to ensure efficient cooling down and practically silent work. Dual-X system consists of heat pipes and two fans, the bearings of which accommodate dirt-repellent coverage.

All models of Sapphire Flex series are able to support three DVI monitors in Eyefinity mode and create SLS conditions without the employment of active adapters. Two monitors are connected to the DVI ports, while the third one – to the HDMI to DVI connector. In addition, customers have got real opportunity to connect up to five monitors simultaneously due to the availability of two DisplayPort sockets. This might serve a good background for the creation of solutions for …

Promising Speed Forecasts for AMD Radeon 8000 Sea Islands

AMD is continuing its work on the new GPU generation codenamed ‘Sea Islands’. The new series is prognosticated to be released in the coming winter. All the products with this GPU will be branded Radeon 8000. AMD manufacturers claim that their new graphic processing units will be 40% more efficient due to the implemented advanced technologies. There is not so much news about the future GPU architecture, although cardinal changes are barely possible.

Sea Islands chips will be equipped with 5.1 billion transistors as compared with the current 4.3 billion items applied in the products. This augmentation will facilitate the increment of efficiency. The chips will be developed according to the already tried-and-proven 28 nm technological requirements. The increase of transistors is not as large due to the adherence to the ascribed norms. It should be underlined that the implementation of the old technologies does not imply the considerable warming up of the chips; the developments …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.

The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.

As the advantages of such solution can immediately be noted a lower price, due to less stringent …
