• iPhone 6 Plus vs Samsung Galaxy note 7 and the Galaxy S7: comparison of characteristics

    In early August, Samsung officially unveiled the Galaxy note 7. Phablet was pretty good, but in the mobile market there are many smartphones with large screens, which is unable to compete with the latest flagship of Samsung. However, the main rivals Galaxy note 7 are considered to be the Galaxy S7 edge and iPhone 6s plus. Which one is better?

    iPhone 6S plus was presented almost a year ago. In a month Apple will show its successor, although at the moment he is still a current flagship with a 5.5-inch full HD display. Samsung Galaxy S7 edge offers the same diagonal display, but with a resolution of Quad HD. A new model of Galaxy note 7 is characterized by the 5.7-inch screen with a Quad HD resolution and a protective glass Corning Gorilla glass 5. The latter, as we have seen, the fall is stronger than its predecessors, but it is much less scratch resistant.

    We have to admit that all three devices have several common traits. For example, 64-bit architecture processor, premium build quality, software flash for the front camera and the function of “live” photos. As Samsung device, so iPhone 6 plus allow you to make contactless payments and have biometric sensors. All three devices are able to recognize fingerprints, but the Galaxy note 7 there is also a retinal scanner.

    Speaking about the performance, Samsung Galaxy note 7 is equipped with a processor Samsung Exynos 8890 with a clock frequency of 2.3 GHz or a Qualcomm Snapdragon 820 with a frequency of 2.15 GHz, depending on the region. In this respect, features of the Galaxy S7 edge does not differ from it. for iPhone 6S plus features an a chip Apple A9, paired with a coprocessor M9, which is in the background and monitors the activity of the owner. the iPhone can only boast 2 GB of RAM at a time as S7 edge and note 7 have 4 GB of RAM. It seemed that the advantage on the side of Samsung, but only on paper: in real usage iPhone is faster.

    Below you can read the full technical specifications for iPhone 6 plus, Samsung Galaxy note 7 and the Galaxy S7 edge.

    Singapore researchers suggest using hard drives in a special composite material based on an alloy of iron and platinum, which will increase storage density informatsii.Spetsialisty of the Singapore Agency for Science, Technology and Research (A * STAR) proposed a technology that can help significantly increase the density of recording information on magnetic plates, and hence – and increase the capacity of hard drives.
    Let us briefly recall the principle of the hard drive. When an alternating electric current to the read / write head occurs alternating magnetic field acts on the ferromagnetic surface of the disc and reverses the direction of the magnetization vector of domains depending on the magnitude of the signal. Thus, the recording of data. When reading the rotation plate alters the magnetic flux in the magnetic head, which results in a variable electric signal due to electromagnetic induction.

    The smaller size of this field are magnetized, the more information can be recorded per unit area of the disc. In this sense, it is considered very promising alloy of iron and platinum (FePt). Due to the nature of its crystal structure dimensions of the domains may be only a few tens of nanometers. Furthermore, the plates of the alloy are resistant to higher temperature.

    However, to change the status of domain FePt-plates require a much more powerful magnetic field than in the case of conventional drives. Singapore researchers seem to have found a way to solve this problem.
    HOW TO IMPROVE PERFORMANCE hard drives 2It is proposed to use a composite material based on FePt alloy and a special “soft” magnetic material. It is argued that such a composite with exchange connections can significantly reduce the amount of energy required to write data. It may be possible to increase the density of information storage and resistance to thermal effects (the last parameter depends on the share of “soft” matter in the overall structure of the coating).

    The study is published in the publication Journal of Magnetism and Magnetic Materials.

    There are other approaches to increase the capacity of hard drives. For example, the company offers HGST drives fill the sealed unit with helium. This gas has seven times less dense than air, due to which decreases the resistance force acting on a rotating plate, and reduced lateral forces. At the same time good thermal conductivity of helium makes it possible to reduce the heating disks and improve acoustic performance. The result is increased storage density, but the plates may be arranged closer to each other, thus increasing the number of dimensions without changing drives.

  • NVIDIA BATTERY BOOST, OR HOW improve battery life gaming notebook

    New technology implemented in the mobile GPU series GeForce 800M, according to the developers, allows you to raise the “life” of the portable computer away from an outlet twice.
    NVidia company introduced a new generation of graphics processors GeForce 800M, designed for use in laptops. The series consists of chips on the architecture of Kepler, and the newest platform Maxwell. In the top models are equipped with innovative technology Battery Boost, about which we’ll talk.
    Technology nVidia Battery Boost can increase the operating time of laptop battery life in half. (Here and below the manufacturer’s image.)

    The main task of Battery Boost – increasing the battery life of a portable computer to the game mode. nVidia says that depending on the type of game settings and hardware laptop can be achieved double gain. That is to say, instead of hours of virtual battles away from an outlet user will receive two hours.
    How functions Battery Boost? The system provides two ways to save energy. When you start the game without the connection to the mains Battery Boost reduces the frame rate to 30 FPS, or to the value set by the user. After accompanying the application can determine the preferred resolution and choose the optimization for maximum battery life and the best possible picture quality.
    In addition, Battery Boost through nVidia driver interacts with other important components of the notebook – the main processor, memory, display, and so forth. For example, it may be trimmed CPU frequency and reduce the brightness of the screen. Everything happens automatically, without user intervention.
    When working with a relatively undemanding applications (eg, word processing) in the case enters power-saving technology nVidia Optimus. It allows laptop to extend battery life by automatically switching between the discrete video card and integrated graphics controller Intel.
    NVIDIA BATTERY BOOST, OR HOW improve battery life gaming notebook 2Another feature of the series chips GeForce 800M – support system ShadowPlay, previously available in graphics accelerators for desktop computers. It is intended to record gameplay. ShadowPlay uses a hardware encoder H.264, built-in video cards GeForce, to record video in the resolution of 1920 × 1080 pixels at up to 60 frames per second. Supports all games using DirectX 9 or later. Compared with the software tools that are used to record gameplay resources CPU, a hardware solution ShadowPlay degrades performance by only 5-10%, fixing the maximum video quality at bit rates of 50 Mbit / s.

    The GeForce 800M line includes accelerators with the number of CUDA cores to 1 536. You can use up to 8 GB of memory GDDR5. GPUs will be used in powerful gaming laptops and computers for the mass market.

Alas, the new product will be able to buy not everyone: GeForce GTX Titan Z is an impressive 3000 dollars.

    GEFORCE GTX TITAN ZJust a few weeks ago, nVidia introduced the first graphics accelerators at the forefront of architecture Maxwell, coming to replace the Kepler. Meanwhile, the company is already making plans to bring to market a successor Maxwell – platform, code-named Pascal. This architecture includes the use of 3D-memory Stacked DRAM, united with the graphics chip: such an approach will improve communication speed and efficiency. The principle of unified storage (Unified Memory) increase the flexibility of the system due to the fact that the CPU can access the memory GPU, and vice versa. Finally, the product Pascal planned to use high-speed interface NVLink.
    In addition, nVidia announced a platform for developers Jetson TK1 processor-based Tegra K1. This product combines the central processing units and graphics. The first contains four main and one auxiliary core, the second core has 192 CUDA (architecture Kepler). Jetson TK1 configuration includes 2GB of RAM, 16GB of storage capacity and a set of interfaces. nVidia calls Jetson TK1 first mobile embedded systems to supercomputers.
