Operators stop giving out gift SIM cards

Published

on

Vimpelcom (Beeline brand) refused to distribute free SIM-cards as a gift when concluding a contract or when purchasing devices at the operator’s retail. MegaFon has reduced the number of such SIM-cards.

Operators are saving on the background of rising cost of SIM-cards due to a shortage of chips. It is believed that this may have a negative impact on the growth statistics of subscriber bases. Market participants admit that the measure will be temporary and companies will return to the practice of distributing SIM cards when they become more available.

MTS says that “it has long abandoned the extensive increase in the subscriber base, focusing on customer loyalty and reducing their outflow.” Tele2 declined to comment.

Operators stop giving out gift SIM cards

The prime cost of SIM-cards for operators has increased 2.5 times over the past six months, and the cost of logistics has also increased. “The rise in prices for SIM cards occurred during the pandemic against the backdrop of a global shortage of chips,” said one of the sources.

Operators purchased SIM cards from foreign suppliers (Gemalto, Giesecke + Devrient and GigSky), and now the logistics of purchases have become more complicated, which has led to an increase in their cost. There is a shortage of SIM-cards, as well as their rise in price. Under the conditions of the economic crisis, operators are not ready to spend a lot of money to attract new subscribers.

According to estimates, the number of gift SIM cards in 2021 amounted to approximately 10-20% of the total sales.

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 tested its own Arc A380 graphics card and boasted

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.

AsRock tested its own Arc A380 graphics card and boasted the results

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.
