Success in hardware industry is greatly relied on the technologies applied by the manufacturers, quality of products and the frequency of new releases. The development of new technologies and quality of the produced items demands sufficient resource base and bright intellectuals who can influence the frequency of new releases. Here everything is interrelated. Arctic Cooling AG company does not sacrifice any of the success aspects and frequently gladdens its clientele with outstanding products. Arctic Accelero Xtreme 7970 is a bright representative of coolers for Accelero graphics cards which is able to offer multiple opportunities.



Framework Peculiarities


The first peculiar feature that might strike the customers’ eyes is that cooler Accelero Xtreme 7970 framework does not differ a lot from its predecessors. It is equipped with three 92 mm fans which go in a plastic cover, and with two radiator sections based on five copper heat tubes. This model claims to endure 300 W of …

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 …

A new graphics card of an average efficiency has appeared in the arsenal of HIS manufacturers. Codenamed HIS 7770 iCooler (H777FN1G), the card is targeted those gamers who would like to receive a dual effect: the possibility to play all up-dated games and to satisfy all other graphics requirements for a reasonable price.



Model 7770 iCooler is based on AMD Cape Verde TX GPU, developed under 28 nm technological process and built on Graphics Core Next micro-architecture. It involves ten computing blocks and 640 current processors. The processing unit is expected to operate at the reference 1000 MHz clock frequency. The integrated GPU is accompanied by 1GB of GDDR5 memory which employs 128 bus; its nominal clock frequency starts at 1125MHz, while its effective frequency might achieve the margin of 4500MHz.


HIS 7770 iCooler employs PCI Express 3.0 x16 internal interface. A set of external video interfaces consists of HDMI, D-Sub and Dual-DVI ports that are able to ensure the …
