AMD has announced the Radeon R7 260 graphics card, which will take an intermediate position between the $140 Radeon R7 260X and the $90 Radeon R7 250. Thus, the cost of new items should not exceed $110.

The presented video adapter belongs to the Bonaire family. It has 768 stream processors and 48 texture units. The core frequency of the chip is 1000 MHz, the frequency of 5 GB GDDR1 memory with a 128-bit bus is 6000 MHz.

For the Radeon R7 260, a 28-nanometer manufacturing technology is provided. Claimed performance reaches 1,54 Tflops (trillion floating point operations per second). DirectX 11.2 and OpenGL 4.3 APIs are supported. The maximum value of dissipated thermal energy is 95 W.

The novelty implements TrueAudio hardware sound processing technology. It takes care of complex audio calculations and subsequent mixing, regardless of the load on the processor or video accelerator. The TrueAudio chip is equipped with a variety of digital signal processors optimized for audio processing, supports the Tensilica HiFi2-EP instruction set and Tensilica Xtensa SP floating point calculations. Each core is equipped with 32 KB of instruction cache and 32 KB of data cache, as well as 8 KB of fast memory to speed up local operations. In addition, there is 384KB of shared cache on the chip, and the processor itself can address up to 64MB of GDDR5 memory.

The Radeon R7 260 graphics card will go on sale in mid-January 2014.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Technique is controlled by thoughts 24.04.2013

A group of scientists and engineers from the University of Minnesota presented new results of their interesting work on the creation of thought control technologies. Previously, they have already demonstrated a virtual helicopter controlled by the power of thought. Now scientists are demonstrating well-mastered control of a real quadcopter, a wheelchair and prostheses. In the future, a new non-invasive brain interface (BCI) will allow you to interact with electronic devices without using buttons.

Until now, the most accurate neural interfaces use chips implanted in the brain. The disadvantages of this approach are clear: a traumatic operation, the risk of rejection and infection, and difficult modernization of the neural interface. Scientists at the University of Minnesota are developing a non-invasive interface that can provide the same clear brain scans as implantable interfaces. Such an interface will undoubtedly become a revolution in many areas of science and technology: from interaction with a smartphone to data exchange with an airliner control system.

Currently, the BCI of American scientists is a cap with electrodes and allows you to confidently control the ARDrone quadrocopter. With BCI, volunteers fly a small aircraft through hovering hoops with little to no error. Experiments show that the accuracy of the neural interface increases with prolonged use.

Also, scientists are testing the effectiveness of a non-invasive neural interface when driving a wheelchair and robotic tools that make life easier for paralyzed people. The developers have no doubt that in the future the neural interface will become one of the main ways to control equipment, with the greatest prospects for simple devices that do not require drilling of the skull.

Interestingly, last fall, Chinese scientists from Zheijiang University presented their own version of a neural interface capable of controlling a quadrocopter. It is capable of transmitting simple commands like "fly right" or "go higher". It is simpler than the Minnesota BCI and is assembled from commercially available components. In fact, it consists of a portable electroencephalograph and a wireless laptop.
