Review of Headphones AKG K451

Traditional headphones do not lose their topicality even with the development of high technologies and with the emergence of ever newer gadgets. This fact can be easily explained by their comfort in usage and portability. Headphones are designated for usage in home conditions as well as outdoors or in transport. This accessory is usually bantam, and can be, with certainty, attributed to the class of universal devices. Headphones AKG K451 may be connected practically with any device, starting from MP3 stereo, audio system, and finishing with PC, laptop or iPad.


Basic Features of AKG K451


Headphones AKG K451 are accredited to the class of wired accessories with the bandwidth from 11 to 29000 Hz. Heightened susceptibility of headphones, which reaches up to 126 dB/mW, is considered to be quite an attractive peculiarity. Such susceptibility means that the sounding will be played back with the optimal legibility and volume even if the volume button at the device is set for …

ARM Readies Cortex-A72 and Mali-T880 for Mobile Devices

ARM has just announced a series of solutions for the upcoming next-generation mobile SoC. The most notable developments are Cortex-A72 processor and Mali-T880 graphics. According to the manufacturer, both components will be interconnected within SoC by means of CoreLink – CCI-500. The launch of new items is scheduled for 2016. Rockchip, MediaTek and HiSilicon are among the companies to integrate both elaborations into their products.



It should be noted that Cortex- A72 is a successor of Cortex-A57, taking analogous 64-bit operations but demonstrating three times higher performance. The new-comer will be designed under 16 nm FinFET+ technological process. Its layout corresponds to big.LITTLE framework requirements; this promotes for its combination with other ARM cores.


As far as Mali-T880 GPU is concerned, it provides for 1.8 response time increase if compared with the Mali-T760 model. Herewith, its power consumption is reduced by 40%. Moreover, this GPU might support 4K …

Gigabyte Shows Off a Bespoke GTX 970 Graphics Card

Gigabyte has intrigued its fans by the design of an unusual videocard – the GeForce GTX 970 (GV-N970TTOC-4GD). It is based on Nvidia GM-204-200-A1 GPU (Maxwell) but with overclocked frequencies. The core operates at 1101 MHz/1241 MHz instead of etalon 1050 MHz/1178 MHz. The GPU is accompanied with 4 GB of GDDR5 memory (256-bit bus) that runs at 7010 MHz efficient clock frequency.



Gigabyte GeForce GTX 970 is distinguished by the implementation of Twin Turbo Fan cooling system. It consists of three copper heatpipes with direct touch technology, an aluminum heatsink, and a radial-flow fan; the latter grasps air from both sides of the adapter due to the shortened PCB design.


As a result, the airflow increases by 24%, whereas the cooling effect enhances by 29%. Thanks to this, the card is thought to be an optimal solution for Nvidia SLI configurations.


It should be noted that this graphics card boasts a high-quality hardware base – Ultra Durable VGA. A set of external …
