VIA Technologies Inc., a global manufacturer of power-efficient processor platforms, has recently announced the release of its peculiar motherboard, codenamed VAB-800. The major peculiarity of these motherboards is that they will be delivered in two variants: with chips of VIA personal production, WonderMedia (800 MHz), and with Freescale ARM Cortex-A8 1 GHz chips. The volume capacities of DDR3 memory in either variant will equal to 1 GB. VAB-800 is developed in piro-ITX form-factor but is also compatible with blocks of ATX form-factor.



Motherboard VAB-800 accommodates flash-memory of eMMC type with the integrated SATA 3 Gbit/sec sockets. The total volume capacity of flash-memory equals to 64 GB. This model can boast a large number of internal sockets, including a couple of RS-232, two LVDS (to enable the connection with the up-to-date monitors), SATA, JTAG, SDIO, RTC, and a slot for the activation of the external power supply.

Sapphire Technology Ltd. is going to release a new graphics card on Tahiti LE chip. Codenamed Radeon HD 7870 GHz Edition Toxic, the card is one of the first models to use the newest GPU, developed under 28 nm technological process. The suffix 'GHz Edition' in the model's name witnesses that the nominal GPU clock frequency exceeds the index of 1 GHz.



The core of Sapphire Radeon HD 7870 GHz Edition Toxic is based on Graphics Core Next architecture and contains 1536 current processors. The card's inventory involves 2GB of GDDR5 memory with 256-bit bus interface. The memory modules are known to operate at 6000 MHz frequency. GPU operational frequencies are still not clarified, but it's possible to assume that on activation of AMD PowerTune option the card will demonstrate some outstanding performance. In fact, analysts dare saying that this model is the most efficient one among all other solutions based on Tahiti LE chip.

A new PSU series, codenamed GS (Green Star), has replenished a line of products designed by Huntkey. This series is particularly targeting gamers, providing for the prime facilities and reliability. The models included into the lineup (GS550 and GS450) are equipped with two +12V buses and exclusively high-quality components that promote for the 82% PSU efficiency level. Both models house a 120 mm low-noise fan which is notable by the variable rotational speed.



Upon the whole, Huntkey GS series corresponds to ATX12V V2.3 standard and supports AMD and Intel CPUs. Both models are compatible with graphics adapters designed by Nvidia and AMD. They feature Active PFC which ensures true reliability on different loading conditions. The average time period of foolproof work is estimated at fifty thousand hours. Besides, both units have undergone two types of testing: high voltage and forced failure tests.


GS450 model operates at 200-240VA (50-60Hz) voltage and at nominal 350W. The …
