An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.



Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD …

For the first time the LEPA NEOllusion CPU Cooler was demonstrated during the Computex 2016 exhibition. And the WOW moment is in its unique backlighting: LEDs are located not on the fan, but on the sides of the construction. Besides, their colour and work mode can be modified with the help of the control unit, which can be attached to the metal framework by magnetically charged legs.



The LEPA NEOllusion cooling system features the base, four 6 mm copper heat pipes with a direct contact to the CPU heat dissipation lid, the aluminum radiator and the 120 mm fan (its rotative speed range is 600–1800 rpm or 400–1000 rpm with a set adapter). With the special blades shape and excellent aerodynamic qualities it can pump the air flow of up to 128.12 m3/hr (up to 78.31 m3/hr with an adapter) at the static pressure of 2.41 mm H2O (0.9 mm H2O) and the noise grade of 33 dBA (19 dBA).


LEPA NEOllusion dimensions are 161.7 х 126 х 40 mm, and its weight is 645 g. It is compatible with …

Scythe Co. Ltd., an award-winning Japanese designer of enthusiast-level cooling solutions, has expanded its Ninja series of CPU coolers with another model – Ninja 4. The new-comer boasts 130x155x153 mm dimensions and supports all updated platforms developed by AMD and Intel, including Intel LGA 2011-3. Currently, pricing info and release date remain undefined.



Scythe Ninja 4 consists of a huge aluminum cross-type heatsink with a copper footing, a nickel-plated base, and six nickel-plated U-shape heatpipes. The framework is designed according to M.A.P.S. technology that ensures the maximum airflow; besides, air is able to circulate through the tiniest heatsink ribs.


The mission to provide an efficient airflow is entitled to a single 120 mm fan with texturized blades which reduce turbulence and, correspondingly, the vibration between the heatsink and the frame. The fan, fixed by Back-Plate 2 clamp, is capable to produce up to 84.6 CFM airflow at the maximal noise level of …
