In Kita, a vehicle-mounted maglev technology was successfully tested, during which a 2.8-ton vehicle rose to a height of 35 mm and flew over the road.

The vehicle, developed by Southwestern Jiaotong University in Chengdu, has been heavily modified. For levitation, a permanent magnet structure was installed, and a track was laid along the road that allows the car to levitate.

Maglev machines have been successfully tested in China.  They are already moving at over 200 km/h.

The development of maglev vehicles will be in the spotlight in the coming years, according to Professor Dan Zigang, who hopes the technology can help reduce energy consumption and increase the range of cars in the future.

On the same day, another road test was carried out, this time at 200 km/h. In total, eight vehicles were tested on a 7.9 km section of the route, including five vehicles powered by new energy sources, the maximum speed of which approached 230 km/h.

The tests were organized by the local transport authorities and aimed at studying the design of roads and safety measures for high-speed driving.

Google expects excellent sales of Pixel 7 smartphones

Google expects excellent sales of Pixel 7 smartphones

It seems that despite the fact that the line of smartphones Pixel 7 is not very different from its predecessors, Google believes that they will sell very well.

Google expects excellent sales of Pixel 7 smartphones

The search giant has reportedly ordered 8 million new-generation devices and expects to double sales of new models relative to the Pixel 6 line.

At the same time, we recall that just the other day we learned that in six years Google has sold only 27.6 million Pixel smartphones. That is, the company intends to sell almost 30% of the total number of smartphones sold over six years only for older Pixel 7 devices.

It is also reported that the company has ordered 4 million lower class models, i.e. Pixel 7a models. In total, it turns out 12 million smartphones per year, or almost 45% of the total number of smartphones sold in six years.

We’ll find out how Google’s forecasts come true in about a year, but we can recall that at one time the models of the Pixel 6 line showed a multiple increase in sales relative to their predecessors.

The era of crazy CPU overclocking is back. Core i9-13900K already overclocked to 8.2 GHz

The era of crazy CPU overclocking is back Core i9 13900K

The new Intel Raptor Lake processors, like the GeForce RTX 40 graphics cards, clearly have impressive frequency potential.

The era of crazy CPU overclocking is back.  Core i9-13900K already overclocked to 8.2 GHz

We’ve already seen how the Core i9-13900K can hit 8GHz, and now it’s hitting the 8.2GHz mark. Of course, this is when using liquid nitrogen.

This frequency was achieved only on one core, while the rest worked in the frequency range of 5.7-6.3 GHz.

Judging by the results, the Core i9-13900K is still unlikely to outperform the AMD FX-8370/8150, which top the table of records in terms of frequency with a result of over 8.7 GHz. And even the result of Celeron B 352 at 8543 MHz is unlikely to be beaten, but the Core i9-13900K has definitely already broken all other records among Intel processors, that is, in terms of overclocking, this is the company’s best CPU in almost 20 years.

The GeForce RTX 4080 16GB video card has already shown what it is capable of in 3DMark, but now we can evaluate other features of the adapter.

It turns out that in the same benchmark, the GPU of this video card worked at a frequency of 3 GHz! The card at the same time consumed 333 watts, but surprisingly, the core temperature was only 61 degrees.

True, we do not have exact data on whether the native cooling system was used or, for example, liquid. There is also no data on whether GPU overclocking took place, although the memory frequency corresponds to the reference value. This fact may indirectly speak in favor of the lack of overclocking, but this is not at all necessary.

In any case, what matters to us is that the GPUs on the RTX 4080 and RTX 4090 can run at 3GHz without extreme overclocking.
