Exynos 9820 processor from Samsung

14.11.2018

Samsung has unveiled its new flagship Exynos 9820 processor, which will be the heart of the next generation of the top-end smartphone Galaxy S10. The chip is manufactured using an 8nm LPP FinFET process. According to the developers, this saves 10% of energy compared to products based on a 10-nanometer process.

A three-cluster architecture with six fourth-generation cores was implemented: two specialized, two productive Cortex A75 and four energy-efficient Cortex A55. Chip performance increased by 20% in single-core mode and 15% in multi-core mode.

Overall productivity increased by 40%. The chip is equipped with a Mali-G76 MP12 GPU, also providing 40% more performance. For the first time, Exynos has received a Neural Processing Unit (NPU) that works with artificial intelligence functions seven times more efficiently than its predecessor.

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, ... >>

Mobile phone that works without cellular operators 28.06.2019

Oppo has developed MeshTalk technology that allows you to make calls without using cellular networks. The idea implies decentralized data exchange between Oppo smartphone owners and almost complete independence from mobile operators and their terms of service, including international roaming.

The MeshTalk protocol is a decentralized data transmission system. A key feature of the technology, in addition to working outside cellular networks, is the signal transmission range - users can be up to three kilometers apart, writes The Verge resource. MeshTalk also does not use Bluetooth and Wi-Fi modules in its work. The description of the technology does not provide the frequency of the signal and the list of objects that interfere with its distribution, but, according to Oppo itself, as of June 2019, MeshTalk works at a greater distance compared to other similar technologies.

In fact, MeshTalk is a P2P (peer-to-peer) data exchange network without base stations, servers and other intermediate devices. Turning smartphones into a modern analogue of a walkie-talkie, it provides the interlocutors with maximum confidentiality of conversations.

Hardware technology is implemented in the form of a separate chip located on the motherboard of the smartphone. The module consumes a minimum of energy when transmitting a signal, and when it is activated, the smartphone can last up to three days (72 hours) in standby mode. In this case, the gadget will not spend energy searching for base stations, as is the case with the use of cellular networks.
