Graphics Card Sapphire Toxic HD 7970 GHz Edition Review

Up-to-date facilities provided by graphics cards manufacturers allow customers to create various graphic configurations, including the activation of several monitors within a single card. Indeed, contemporary technical approaches transform traditional video adapters into video gurus. The latest development of Sapphire, a flagship model Toxic HD 7970 GHz Edition, offers up to 6 GB of GDDR5 memory and promotes for the activation of six monitors in Eyefinity. Such options exceed those integrated into a reference model, AMD Radeon HD 7970 GHz Edition, and are able to ensure a dramatic increase in performance.



Technical Peculiarities


Sapphire decided to base its flagship model on GPU AMD Tahiti with an integrated delimiter which lowers the clock frequency on the overshoot of thermal threshold. Its standard frequency equals to 1050 MHz, nominal frequency – 1100 MHz; sill, this GPU features Lethal Boost options that increase the frequencies up to 1200 MHz. This graphics card is …

Zalman Intros Three New Graphics Cards with VF1500 Cooler

Zalman, a well-known manufacturer of CPU coolers, PC cases and graphics solutions, introduces three new graphics card models, codenamed GeForce GTX 600 D5 OC VF1500, GeForce GTX 660 Ti D5 VF1500 and GeForce GTX 660 Ti D5 OC VF1500. All three models are equipped with a brand two-slot VF1500 cooler. Its framework consists of four heatpipes which transfer heat from GPU surface to an aluminum heatsink. This heatsink is accompanied by a couple of 92 mm fans, the maximal rotational speed of which achieves 1500 RPM. If compared with a reference cooler, VF1500 reduces GPU operational temperature at 25 degrees (from 81 to 56 degrees), producing 10 dB less noise (26 dB vs 36 dB).



The first model is based on Nvidia GK106 processor, designed under 28 nm technological process. It is characterized by heightened clock frequencies: nominal 1006 MHz against reference 980 MHz, and dynamic 1059 MHz against reference 1033 MHz.


The other two models, GeForce GTX 660 Ti D5 VF1500 and GeForce GTX …

Xigmatek Intros New CPU Cooler Gaia II

Xigmatek, an outstanding manufacturer of cutting-edge PC components, announces the release of a new CPU cooler, entitled Gaia II. The model is developed in accordance with a traditional tower-like framework and might be truly called a universal cooling solution. It supports a large variety of platforms for processors with TDP level of not higher than 150 W: Intel Socket LGA 775/1366/1156 and AMD Socket AM2(+)/AM3(+)/FM2/FM1.



Cooler Gaia II is designed with the direct implementation of H.D.T. technology (Heat Pipe Direct Touch). This implies that all three copper heatpipes, which stem from the heatsink base, come into direct contact with the CPU surface. The heatpipes themselves have got U-shape structure and 8 mm dimensions. They pierce ‘multi-plate’ aluminum heatsink to provide for a better heat dissipation.


The model is delivered with a pre-installed 120 mm fan with bright orange blades; it is fixed to one of the heatsink sides and housed in a black frame. The fan is …
