New Gigabyte Radeon HD 7970 operates at a frequency of 1100 MHz

Gigabyte presented a new overclocking model of video card Tahiti XT, designated as GV-R797TO-3GD. In comparison to the current Radeon HD 7970 OC (GV-797OC-3GD), the newcomer has some advantages. In particular, it is known that the graphic adapter is based on the graphics chip Radeon HD 7970 GHz Edition that is selected. The clock frequency of the accelerator is increased from 1000/5500 MHz (core / memory) to the 1100/6000 MHz, comparing GV-797OC-3GD. Standard values, recall — 925 MHz GPU with chip and 5500 MHz with GDDR5 microchip.



Externally the video adapter has no changes: the PCB soldered 3 GB of memory, which combines with the GPU on a 384-bit brace. The number of stream processors is unchanged — 2048 units. The design of printed circuit board includes electrical components Ultra Durable VGA. High-effective WindForce 3X cooler consists of a copper base, a few copper heat pipes and three 80-mm fans.


Unlike its predecessor, Gigabyte GV-R797TO-3GD has a gold plated …

Biostar Launches High-Performance Motherboards TZ77B

Biostar has recently introduced its new series of motherboards, codenamed Biostar TZ77B, and is currently starting mass delivery of them to the market. TZ77B model is developed on Intel Z77 logics kit and goes in ATX form-factor. Manufacturers claim that the new series is able to ensure high performance and stability of operation at moderate price. These motherboards support all LGA1155 processors Intel Core (i3, i5 and i7) of the 2nd and 3rd generation.



Powerful graphics core DirectX 11, integrated into Intel Core processors (of the third generation), enables the compatibility with the majority of up-dated 3D games and HDMI 3D Visual technology.

Biostar TZ77B proves to demonstrate up to 95W TDP level, including unblocked CPU with K index. The motherboard …

Cougar Vortex Fans: the Secret of Success

Nowadays a lot of hardware developers employ Vortex fans from Cougar in the design of various PC components, including CPU coolers and graphics cards. Such demand is primarily explained by an elaborate approach to the fans' framework construction. Profound testing is not the last thing to contribute to the company's success. Indeed, since the launch date in 2011, Vortex line has been enjoying great popularity throughout the world and, especially, on American and European markets.



Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.


All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …
