Outstripped Tesla Cybertruck. The first test drives of the electric pickup Rivian R1T appeared

Published

The Rivian R1T is the world’s first all-electric production pickup. Of course, except for the strange micromachines from the Middle Kingdom.

The R1T went into production at the beginning of the month, and now the first test drives have appeared on the web. Thanks to this, we can learn the impressions of journalists from a machine that is actually unique for the market at the moment.

To begin with, the car is almost indistinguishable from the prototype that Rivian showed a few years ago. The changes are generally minimal, although there is one very important thing: the charging power was increased from 160 to 250 kW.

You can evaluate the design and interior in the photographs. Inside you can see a very large display of the infotainment system, which unfortunately does not support CarPlay or Android Auto. There are no third-party apps other than Spotify, but the company is promising a software update soon to expand availability. The reviewer also praised the sound system and the many cameras that make it easier for the driver to work in certain conditions. Off-road, the car showed itself well. Of course, within the framework of the race organized by the manufacturer, no super-extreme situations were encountered, but nevertheless it could not be called an ordinary walk. At the same time, energy consumption amounted to about 4.8 km / kW • h.

One of the interesting features of the pickup is a special compartment behind the cab, located at the bottom. There you can place long items, bags, and a person, if necessary, can fit. And it is also there that a special camping kitchen kit can be located, which will be available as an option for $ 5,000.

But the early announced possibility of turning in place is not yet available and will appear later.

As a result, most of the journalists were delighted with the car, although they noted a number of shortcomings and shortcomings. For example, not the most responsive interface of the multimedia system. It is worth remembering, however, that the Rivian R1T costs around $ 70,000, which automatically makes it not a car for everyone.

Intel introduced Arc Pro A40 and Arc Pro A50 graphics

Everyone is waiting for real gaming graphics cards of the Arc line from Intel, but the company is in no hurry. But today, the range of Intel video cards has been replenished with two discrete models at once – Arc Pro A40 and Arc Pro A50. As the name suggests, they are designed for professional use. However, the characteristics are modest, so this most professional application will be limited.

Intel introduced Arc Pro A40 and Arc Pro A50 graphics cards.  But these are not the models that ordinary users and gamers are waiting for.

Both models have 6GB of GDDR6 memory, support real-time ray tracing and AV1 hardware encoding, and feature four Mini DP 1.4 ports. Arc Pro A40 has a peak consumption of 50 W, this card is a single-slot version, Arc Pro A50 is a dual-slot version, and its peak consumption is 75 W. Performance in the first case is 3.5 TFLOPS with single precision, in the second – 4.8 TFLOPS. For comparison, the performance of the old Radeon HD 6970 (it came out at the end of 2010) is 2.7 TFLOPS.

Together with discrete solutions, the Intel Arc Pro A30M mobile GPU is also presented – it is in many ways similar to the Arc Pro A40, only there is less memory (only 4 GB GDDR) and the power consumption level is adjustable – from 35 to 50 watts. The new Intel GPUs will appear in off-the-shelf products later this year.

Japan has developed the worlds fastest quantum processor

Japanese physicists have created a two-qubit quantum processor with a record high speed. This was reported by the press service of the National Institute of Natural Sciences of Japan (National Institute of Natural Sciences – NINS). A group of scientists led by Professor Kenji Omori has created a processor based on Rydberg atoms. These particles play the role of qubits – quantum analogues of ordinary bits. This development was based on atoms of rubidium-87, cooled to near absolute zero and located at a distance of one micron from each other.

The last electron of such an atom is moved a long distance from the nucleus with the help of special pulses of laser radiation – ultrashort, but very powerful. Such pulses transfer neighboring atoms to the Rydberg state, make them interact and participate in the calculation of logical operations. As a result, the processor spends only 6.5 nanoseconds per operation, which is about a hundred times faster than previously achieved on other quantum computers based on cold atoms.

An important factor is the ability of the Japanese development to circumvent some of the limitations that exist for quantum computers. The accuracy of the calculations of quantum processors reduce noise from the external environment and the operating laser. But in this case, one logical operation is performed approximately two orders of magnitude faster than noise occurs in the operation of qubits. In theory, this allows you to ignore their effect on the computer. According to scientists, the new development will lead to the creation of quantum computers capable of performing hundreds of millions of operations per second.

AsRock recently introduced its new Challenger ITX graphics card based on the Arc A380 graphics chip. And now, without postponing the matter indefinitely, I made a review on it.

According to the manufacturer, this is a factory overclocked card with a GPU clock speed of 2250 MHz. However, in real tests it came out. For example, in the Furmark stress test, it reaches 2300 MHz, and in games – 2450 MHz.

Under full load, the fan speed reaches 1683 rpm and the chip temperature is 85°C. The power of the board, according to Furmark, is 54.9 W, which is less than the reference version of the Arc A380, where the TDP is 75 W.

In addition to benchmarks, ASRock has also tested the performance of several games, including popular AAA titles and modern DirectX12 API games. Testing was conducted at 1080p resolution.
