HIS Adds 7770 iCooler to Its Graphics Cards Arsenal

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 …

Kimdecent created a computer Droid Stick T4 for lovers of small devices

Personal computer — this has long been not only a cumbersome system unit and monitor, as this phrase is now called nettops and more compact devices of class «micro-PC.» For public discussion was presented the computer Droid Stick T4 from a Chinese company Kimdecent, barely surpassing dimensions of a standard USB-stick with its size.

Initially, the micro-PC Kimdecent Droid Stick T4 comes with preinstalled Google Android, updated to version 4.0.4 Ice Cream Sandwich, but the manufacturer provides the ability to install any other distro. The only requirement is to it — the support of processors with the architecture of ARM. By the way, a modification of Linux Ubuntu can work with it.

The system in this case is on the internal flash memory of 4 GB, which can be increased through the use of cards microSD. Supported capacity — 32 gigabytes. Kimdecent Droid Stick T4 is based on the processor Allwinner A10 dual-core and 1.5 GHz. Full-time package includes a 1-gigabyte memory …

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 …
